Figure 18 and Figure 19 shows the detailed configuration of the auxiliary-blade 14 set on the rear portion of razor head 2.As described above, auxiliary-blade 14 movable blade 29 is made of the comb for having cutting blade 29a in front and back, and fixed blade 31 is formed by slit blade, But in order to effectively by frizzle, becoming mildewed imports the inside of fixed blade 31, following to constitute fixed blade 31.Fixed blade 31 is by hanging down Straight longitudinal wall and continuous with longitudinal wall and bend backwards upper wall at an acute angle and be formed as the shape of falling V, the blade face of upper wall be equipped with The cutting region R1 of 29 sliding contact of movable blade and not with the fluffing region R2 of 29 sliding contact of movable blade.Also, it is rising Fixed blade 31 in the R2 of hair-fields domain is equipped with locally in arc-shaped and in the fluffing promotion division (outwardly projecting portion) 123 of evagination shape, can Tighten skin surface on one side concave while come effectively make frizzle, fluffing of becoming mildewed.Fluff promotion division 123 from movable blade 29 The curved base of the adjacent upside in inclination lower end rise and be bent to semicircle shape throughout vertical longitudinal wall.

As shown in figure 18, in cutting region R1, the small blade 31a and slit (knife of rib shape are formed with separating certain intervals Film perforation) 31b, fluffing region R2, be also formed with identical small blade 31c and slit 31d.Cut off the small blade in the R1 of region 31a and slit 31b to deviate the state tiled serpentine of a spacing size of the cutting blade 29a of movable blade 29 to the left, Fluff region R2 in small blade 31c and slit 31d with complications after small blade 31a and slit 31b it is continuous.In this way, if rising Be formed with slit 31d in the R2 of hair-fields domain, then it can be by the frizzle after being fluffed by fluffing promotion division 123, becoming mildewed imports in slit 31d And it prevents from falling down to skin surface.If also, cutting off in the small blade 31a in the R1 of region and slit 31b and fluffing region R2 Small blade 31c and slit 31d are continuous in the longitudinal direction, then can by by fluff region R2 slit 31d capture frizzle, It becomes mildewed in the state of keeping fluffing towards the slit 31b guidance of cutting region R1, is made so as to be assuredly shut off Undercoat.

In Figure 19, when the thickness of fixed blade 31 is set as T1, by fluff region R2 in fluffing promotion division 123 with Protrusion size on the orthogonal direction of inclined upper wall (inclined surface) is set as T2, the promotion division 123 that will fluff in vertical direction Protrusion size be set as T3 and by from fluffing promotion division 123 flexure plane to the slanted upper end of fixed blade 31 until hang down When the upward protrusion size of histogram is set as T4, each size T1~T4 is preferably set to meet inequality below.(R1 < R2) (T1 < T2) (T2 < R2) (T4 < T3) (T1 < T4 < T2 < T3).

As described above, small blade 31a, 31c's is complete if continuous before and after making small blade 31a, 31c and slit 31b, 31d Length is elongated, is become easy correspondingly to inside and outside deformation.But obliquely due to the bridge 124 in cutting region R1 Complications, in addition obliquely the part of the small blade 31a of complications is accepted by movable blade 29, so even if to fluffing promotion division In the case where the pushing reaction force of 123 effect skin surfaces, the concave change of small blade 31a in cutting region R1 can be also prevented Shape, so as to be assuredly shut off frizzle, become mildewed.As shown in figure 19, in the sliding of the small blade 31a accepted by movable blade 29 Face is equipped with through the bridge 124 of the concave formation of half-etching, by by the bridge 124 by adjacent small blade 31a, 31c Bridging is formed as one them each other, the upward intensity of Lai Tigao small blade 31a, 31c, to prevent from deforming.

If also, part is set as the inclination from fixed blade 31 in the forming position of the fluffing promotion division 123 of arc-shaped Upper end can then mitigate the skin feel of fluffing promotion division 123 downward away from the position of size T4.

If the size relationship of the protrusion size T2 and fluffing region R2 from inclined surface of fluffing promotion division 123 are set as full Sufficient inequality (T2 < R2) can be improved the structural strength of fluffing promotion division 123, then so as to substantially ensure fluffing promotion division 123 intensity.

The curved base of the forming region for promotion division 123 of fluffing from the upside adjacent with the inclination lower end of movable blade 29 is straight To the vertical longitudinal wall of rear side.Also, it cuts off region R1 to be formed before lower from the upper front end of the cutting blade 29a of movable blade 29 End.In addition, the size relationship of cutting region R1 and the region R2 that fluffs are (R1 < R2).It is constructed according to such fluffing, due to energy It is enough that fluffing promotion division 123 is set as the biggish curved shape of radius of curvature, so skin feel can be made to become good.

If the size relationship of prominent size T3 and prominent size T4 are set as meeting inequality (T4 < T3), promote fluffing It is suitably prominent from the inclined surface of fixed blade 31 into portion 123, can be effectively performed become mildewed, the fluffing of frizzle.

When the thickness of fixed blade 31 is set as T1, by fluff promotion division 123 with fixed blade 31 it is inclined on When prominent size outstanding is set as T2 on the orthogonal direction of wall, if its size relationship is set as meeting inequality (T1 < T2), It can be improved the hairy effect of fluffing promotion division 123.

If the size relationship of each section is set as meeting inequality (T1 < T4 < T2 < T3), can on one side effectively into Row becomes mildewed, the fluffing of frizzle, and the skin feel for the promotion division 123 that makes to fluff on one side is soft and good.

Using following reciprocating motion type electric shaver as object: razor head 2 be equipped with have movable blade 21,22 and Front and back a pair of cutter blades 11,12 of fixed blade 23,24 drive a pair of of oscillator 16,17 of each movable blade 21,22 to configure Set on the inside of the head shell 15 of razor head 2, it is equipped between motor 6 and a pair of of oscillator 16,17 and moves the rotation of motor 6 Power-supply change-over mechanism of the force transformation at reciprocating power, the reciprocating power drive that a pair of of oscillator 16,17 is exported by driven force transforming mechanism It moves and mutually oppositely moves back and forth.And, which is characterized in that at least one oscillator 16,17 is by being set to another oscillator 16,17 Guide seat 51,52 support.

It is constructed according to above-mentioned oscillator, even if negative via 11,12 pairs of stronger pressings of the effect of oscillator 16,17 of cutter blades In the case where lotus (skin reaction force), an oscillator 16,17 can also be undertaken support by another oscillator 17,16.Therefore, energy Enough a part deformations or damaged for preventing oscillator 16,17 well.

A kind of reciprocating motion type electric shaver is equipped in razor head 2 and has movable blade 21,22 and fixed blade 23,24 front and back a pair of cutter blades 11,12, drive each movable blade 21,22 a pair of of oscillator 16,17 configure be set to shave The inside of the head shell 15 of cutter head 2 is equipped between motor 6 and a pair of of oscillator 16,17 and is transformed into the rotary power of motor 6 The power-supply change-over mechanism of reciprocating power, a pair of of oscillator 16,17 are mutual by the reciprocating power driving that driven force transforming mechanism exports Oppositely moving back and forth, which is characterized in that an oscillator 17 is supported by the first guide seat 51 for being set to head shell 15, another Oscillator 16 is supported by the second guide seat 52 for being set to said one oscillator 17.

According to the electric shaver of above structure, even if stronger via 11,12 pairs of effects of oscillator 16,17 of cutter blades In the case where pressing load (skin reaction force), since an oscillator 17 is accepted by the first guide seat 51 of head portion shell 37 Support is sunk so being also reliably prevented from the oscillator 17 to pressing load direction.Similarly, since another oscillator 16 is by upper The second guide seat 52 for stating an oscillator 17 receives, so can prevent the oscillator 16 from sinking to pressing load direction.Therefore, energy Enough a part deformations or damaged for preventing oscillator 16,17 well.Also, since an oscillator 17 is by being set to head portion shell 37 the first guide seat 51 undertakes support, so the support becomes firm, can prevent deformation, the breakage of oscillator 17 well. In addition, another oscillator 16 for being supported in an oscillator 17 is also stably supported.

Power-supply change-over mechanism have the output shaft for being fixed on motor 6 eccentric cam 54 and be set to an oscillator 17 and by The operand 53 that above-mentioned eccentric cam 54 is back and forth driven.Being equipped between an oscillator 17 and another oscillator 16 will be above-mentioned The reciprocating action of one oscillator 17 is transferred to the transmission body 38 of another oscillator 16.

According to above-mentioned drive structure, it will reliably can be driven by power-supply change-over mechanism via transmission body 38 and back and forth be moved The reciprocating action of dynamic oscillator 17 is transferred to another oscillator 16, so as to drive it is corresponding with each oscillator 16,17 can moving knife Piece 21,22 is allowed to mutually oppositely move back and forth.Also, due to providing at least one oscillator 16 by guide seat 52 and transmission body 38 Reciprocating action cut so always can suitably make oscillator 16 reciprocatingly slide so as to effectively further carry out beard It is disconnected.

Head shell 15 has head shell 36 and head portion shell 37.Between the upper surface of a pair of of oscillator 16,17 The central portion of kinematic link 38 be pivotally supported by the swing axis body 56 for being downwardly projected setting from head portion shell 36 as can be reciprocal It swings.The pressing body 62 of the upward movement of limitation kinematic link 38 is equipped in head portion shell 36.

According to above-mentioned drive structure, due in addition being set with axis body 56 and pressing body 62 will be swung as independent component The case where setting is compared, and number of components can be reduced, and does not in addition need to be pivotally supported kinematic link 38 using stopping wheel etc. For that can swing, so the support structure of kinematic link 38 can be simplified to reduce cost.Also, due to being set to oscillator 16,17 Upper surface between kinematic link 38 by pressing body 62 press keep, so kinematic link 38 from each oscillator 16,17 float The leeway left is acted, therefore further can reliably carry out the transmission of the reciprocating action of kinematic link 38.

Pressing body 62 is made of the limitation protrusion being formed as one with head portion shell 36.

In this way, if pressing body 62 is made of the limitation protrusion being formed as one with head portion shell 36, with pressing body 62 It is compared the case where formation as independent component, the support structure of kinematic link 38 can be simplified to reduce cost.Also there is energy Enough the advantages of reducing the labour assembled and time.

It swings axis body 56 and has the axle portion 60 for being pivotally supported kinematic link 38 and the step being formed in around the upper end of axle portion 60 Portion 61.Stage portion 61 abuts to limit the upward movement of kinematic link 38 with the upper surface of kinematic link 38.

As described above, if the oscillation center of kinematic link 38 is accepted to limit the upward shifting of the connecting rod 38 by stage portion 61 It is dynamic, then it can make the swing resistance minimum limit for acting on kinematic link 38, so as to keep kinematic link 38 smooth and proper Local reciprocally swinging.Therefore, the transmission of the reciprocating action between adjacent oscillator 16,17 further can accurately be carried out.

It is energy that an oscillator 17 for having operand 53 is supported by the first guide seat 51 guidance for being set to head portion shell 37 Enough horizontally slip.Another oscillator 16 can be horizontally slipped by being set to the second guide seat 52 guidance support an of oscillator 17.

It is constructed according to such oscillator, since a pair of of oscillator 16,17 is respectively by the first guide seat 51 and the second guide seat 52 Guidance support, so even if (skin is counter to be made having stronger pressing load via 11,12 pairs of effects of oscillator 16,17 of cutter blades In the case where firmly), it also can further be reliably prevented a part deformation or damaged of oscillator 16,17.Further, it is possible to disappear The case where becoming smaller except the driving trip of the transmission loss of motor power, movable blade 21,22, so as to effectively further into The cutting of row beard.

Sliding frame portion 16b, 17b is respectively formed in a pair of of oscillator 16,17.By a pair of of the guiding axis for being assemblied in head shell 15 48,50 pairs of sliding frame portions 16b, 17b carry out sliding guidance, to the guidance of each oscillator 16,17 be supported can only to horizontally slip.
