Referring also to fig. 5, the bottom wall 20a of the electrical component housing box 20 is formed to support substantially a half of the outer circumference of the lower end wall 28c of the canister 28, and a discharge connection pipe 41 and an atmosphere introduction connection pipe 42 are provided to protrude from the lower end wall 28c at a portion not covered by the bottom wall 20 a. A discharge hose 43 having one end connected to the discharge connection pipe 41 extends rearward through a lower portion of the electrical component housing box 20.

Further, one end of an atmosphere opening tube 44 that is an atmosphere opening tube for introducing atmosphere into the canister 28 is connected to the atmosphere introduction connection tube 42, a distal end opening 44a of the atmosphere opening tube 44 extending below the electrical component housing box 20 is held by a tube holding portion 45 in order to prevent water from entering the electrical component housing box 20, and the tube holding portion 45 is formed at a lower portion of the electrical component housing box 20 so as to be disposed above a crankcase 59 of the engine body 11 and below the battery 24 in a side view.

The pipe holding portion 45 is constituted by a holding wall 47 and a pair of restricting ribs 48, the holding wall 47 protrudes downward from the bottom wall 20a in the vicinity of the boundary between the battery housing portion 21 and the canister housing portion 22 and has a holding hole 46 through which the atmosphere opening hose 44 is inserted and held, the pair of restricting ribs 48 abuts on a front end opening portion 44a of the atmosphere opening hose 44 at a position spaced rearward in the vehicle width direction from the holding wall 47, and the restricting ribs 48 protrude from an enclosing wall 49 provided to be continuous with the bottom wall 20a so as to enclose the front end portion of the atmosphere opening hose 44 penetrating through the holding wall 47 from below and forward.

An atmosphere opening hose housing portion 58 that is separated from the battery housing portion 21 is formed below the battery housing portion 21 by the holding wall 47 and the surrounding wall 49, and the distal end opening portion 44a of the atmosphere opening hose 44 is housed in the atmosphere opening hose housing portion 58. Thus, even if foreign matter such as condensed fuel leaks from the atmosphere opening hose storage portion 58, the liquid does not enter the battery storage portion 21.

In fig. 2 again, a starter electromagnetic switch 50 is housed in the switch housing portion 23 of the electrical component housing box 20, and the starter electromagnetic switch 50 is disposed at a position where the canister 28 is sandwiched between the starter electromagnetic switch 50 and the battery 24. The rubber-made switch holder 51 attached to the starter electromagnetic switch 50 has a pair of second latching holes 52 in a slit shape, and the starter electromagnetic switch 50 accommodated in the switch accommodating portion 23 is fixedly held in the electrical component accommodating box 20 by inserting a pair of second holding ribs 53 provided in the electrical component accommodating box 20 so as to protrude from both front and rear end portions of the switch accommodating portion 23 in the vehicle front-rear direction into the second latching holes 52.

The second holding rib 53 is formed to extend in the vehicle width direction, and by moving the switch holder 51 in the vehicle width direction, the insertion and removal of the second holding rib 53 into and from the second locking hole 52 can be switched, and the starter electromagnetic switch 50 can be inserted and removed from the switch housing portion 23 from the outside in the vehicle width direction.

In addition, the battery 24, the canister 28, and the starter solenoid switch 50 in the state of being housed in the electrical component housing box 20 are covered with a side cover 54 (see fig. 1) that is detachable together with the control valve 36.

Next, the operation of the embodiment will be described, and since the battery 24 having the front side wall 24b inclined rearward and upward and the canister 28 disposed along the front side wall 24b are housed in the electrical component housing box 20 attached to the vehicle body frame, the battery 24 and the canister 28 can be disposed compactly. Further, since both the battery housing portion 21 housing the battery 24 and the canister housing portion 21 housing the canister 28 have a shape that is open to the outside in the vehicle width direction, the battery 24 is housed in the battery housing portion 21 so as to be able to be inserted and removed from the outside in the vehicle width direction, and the canister 28 is housed in the canister housing portion 21 so as to be able to be inserted and removed from the outside in the vehicle width direction, it is possible to improve the positioning property, improve the maintainability, and improve the assemblability.

Further, since the first holding rib 31 is provided so as to protrude from the electrical component storage box 20, and the first holding rib 31 is inserted in the vehicle width direction through the first locking hole 30 of the canister holder 29 that holds the canister 28, the canister 28 can be inserted into and removed from the canister storage portion 22 from the outside in the vehicle width direction, and the canister 28 can be reliably positioned and easily mounted to the electrical component storage box 20.

Further, since the duct holding portion 45 that holds the distal end opening portion of the atmosphere opening hose 44 connected to the canister 28 is formed in the lower portion of the electrical component housing box 20 so as to be disposed below the battery 24 in a side view, even if foreign matter such as condensed fuel is discharged from the atmosphere opening hose 44, the foreign matter does not affect the battery 24.

In addition, since the canister 28 has: a cylindrical side wall 28a facing the front side wall 24b of the battery 24; and an upper end wall 28b and a lower end wall 28c which are connected to the upper and lower end portions of the side wall 28a at right angles and inclined upward and forward, wherein the upper end portion 24ba of the front side wall 24b is disposed above the rear end portion 28ba of the upper end wall 28b, and the terminal 27 disposed above the rear end portion 28ba of the upper end wall 28b in a side view is disposed on the upper front side of the battery 24, so that even if a liquid dripping onto the upper end wall 28b of the carbon canister 28 flows rearward for some reason, the liquid can be prevented from adversely affecting the terminal 27. For example, the supply connection pipe 32 is provided above the terminal 27 on the upper end wall 28b of the canister 28 in a side view, and even if liquid should leak from the connection portion between the supply connection pipe 32 and the supply hose 34, the leaked liquid does not adversely affect the terminal 27.

Further, since the electrical component housing box 20 has a bottom wall 20a that constitutes the bottom of the battery housing portion 21 and the canister housing portion 22 and is inclined upward and forward, and the length direction of the battery 24 housed in the battery housing portion 21 and the canister 28 housed in the canister housing portion 22 are set orthogonal to and parallel to the bottom wall 20a, the battery 24 and the canister 28 can be housed in the electrical component housing box 20 with good space efficiency.

Further, since the canister 28 is disposed between the engine body 11 and the fuel tank 13 in a side view, the supply hose 34, which is a pipe between the fuel tank and the canister 28, can be shortened.

Further, since the switch housing portion 23 for housing the starter electromagnetic switch 50 is formed in the electrical component housing box 20, and the starter electromagnetic switch 50 is disposed at a position where the canister 28 is sandwiched between the starter electromagnetic switch 50 and the battery 24, the electrical components can be more compactly disposed in the electrical component housing box 20, and the starter electromagnetic switch 50 is disposed diagonally forward of the canister 28, whereby it is possible to prevent dripping from the canister 28 from falling onto the starter electromagnetic switch 50.

While the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various design changes can be made without departing from the gist thereof.
