Disclosure of Invention

Problems to be solved by the invention

However, in the device disclosed in patent document 1, since the lamp unit is attached to the mirror housing only by the engagement between the engaging claw and the locking portion without the need of screw fastening, when an impact is applied to the mirror housing from the outside, the engagement between the engaging claw and the locking portion is released, and the lamp unit may fall off from the mirror housing.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a door mirror device capable of preventing a lamp unit from falling off a mirror housing even when an impact or the like from the outside is applied to the mirror housing.

Means for solving the problems

In order to achieve the above object, the present invention is a door mirror device including: a mirror case having a mirror housing recess for housing a mirror; and a lamp unit having a side turn lamp with a part facing a slit formed in the mirror housing, wherein an engaging claw provided on one of the lamp unit and the mirror housing is engaged with an engaging portion provided on the other of the lamp unit and the mirror housing, and the mirror housing includes: a case main body having the mirror housing recess and supported to be rotatable by a base member attached to a side door of a vehicle; and a cover attached to the housing main body so as to cover the housing main body from a side opposite to an opening direction of the mirror housing recess, the cover having the slit formed therein, the cover being provided with a restricting portion that restricts displacement of the engagement claw from the engagement portion in an engagement/disengagement direction.

In addition to the configuration of the first aspect, the present invention is characterized in claim 2 in that the engaging claw is integrally provided on the case main body, and the restricting portion is integrally provided on the cover so as to protrude in a rib shape toward the case main body so as to be close to and opposed to the engaging claw when the cover is attached to the case main body.

In addition to the configuration of the second aspect, the present invention is characterized in that in the third aspect, the restricting portion has a guide portion that guides the attachment of the cover to the housing body by coming into contact with a distal end portion of the engaging claw when the cover is attached to the housing body.

Effects of the invention

According to the first aspect of the present invention, since the displacement of the engagement claw from the locking portion in the engagement releasing direction is restricted by the restricting portion, the lamp unit can be attached to the housing main body of the mirror housing by the engagement of the engagement claw with the locking portion, so that the cost can be reduced, and the lamp unit can be prevented from falling off from the housing main body of the mirror housing even if an impact or the like from the outside is applied to the mirror housing.

Further, according to the 2 nd aspect of the present invention, since the engaging claw is integrally provided in the case main body and the restricting portion that is adjacent to and faces the engaging claw is integrally provided in the cover so as to protrude in a rib shape toward the case main body when the cover is attached to the case main body, the displacement of the engaging claw in the engagement releasing direction can be restricted only by attaching the cover to the case main body.

Further, according to the 3 rd aspect of the present invention, when the cover is attached to the housing main body, the guide portion of the restricting portion comes into contact with the distal end portion of the engaging claw, thereby guiding the attachment of the cover to the housing main body side.
