  By the way, in assembling the storage box 31 to the vehicle body frame F, first, the step of fixing the box constituting member 33 to the vehicle body frame F, the rear part of the pair of left and right upper down frames 15. And a step of assembling the storage box 31 by attaching a box component member 33 from the side to the box main body 32 disposed between the pair of left and right rear frames 20... The step of attaching to F is sequentially executed. When the step of attaching the box constituent member 33 to the box main body 32 is executed, the electric wire 67 connected to the battery 36 and the fuse box 37 to be accommodated in the electrical component storage chamber 35. ... is inserted through the notch 66 of the box component 33. In the electric wire 67 ... a to sandwich between the cutout portion 66 and the box body 32 so as mounting the box constituent member 33 to the box body 32.

  Next, the operation of this embodiment will be described. The storage box 31 includes a box body 32 disposed between the upper down frame 15, the seat rail 17, and the rear frame 19 that are paired on the left and right sides of the storage box 31. A box constituent member 33 detachably attached to the box main body 32 so as to constitute a part of the wall portion, and the box constituent member 33 is a plan view in a state of being attached to the box main body 32, The box body 32 overlaps with the right upper down frame 15 and the right seat rail 17 which are at least a part of the upper down frame 15, the seat rail 17, and the rear frame 19 on both sides of the box body 32. It is formed to bulge from. Therefore, regardless of the shape of the vehicle body frame F, the degree of freedom of the overall shape of the storage box 31 can be increased and the storage capacity can be increased.

  The box component 33 is attached to the lower part of the box body 32 so as to form the electrical component storage chamber 35 in cooperation with the hanging part 32a of the box body 32, so that the opening width of the upper opening end of the storage box 31 is increased. It is possible to increase the storage capacity without increasing the size of the vehicle, and it is not necessary to increase the width of the riding seat 21 above the storage box 31, thereby reducing the footing of the passenger sitting on the riding seat 21. There is nothing.

  A box component 33 is attached to the lower part of the box body 32 from one side of the motorcycle in the left-right direction (right side in this embodiment), and the battery 36 and the fuse box 37 are stored in the left-right direction side by side. Since the electrical component storage chamber 35 is accommodated in the chamber 35, the width of the electrical component storage chamber 35 is expanded without being restricted by the upper and lower frames 15 and the seat rails 17 that are paired on the left and right sides, and the battery 36 and the fuse box 37 are arranged side by side. It is possible to store in the electrical component storage chamber 35, and it becomes unnecessary to secure an empty space in the front-rear direction between the pair of left and right upper down frames 15 and the seat rails 17, so that the degree of layout freedom can be increased.

  Further, the passenger seat 21 is rotatably supported by the storage box 31 via a hinge 40, and an opening 42 through which the damper rod 41 provided between the vehicle body frame F and the front seat 21a of the passenger seat 21 passes is provided. Since the box body 32 is provided at a position separated from the electrical component storage chamber 35, the damper rod 41 has a larger storage capacity than the case where the damper rod 41 is disposed in the electrical component storage chamber 35. The influence which 41 gives can be suppressed.

  Further, a protruding portion 33a that protrudes to the side of the mounting portion of the box component member 33 to the box body 32 is provided on the box component member 33, and a lid portion 33b that forms a small storage chamber 45 between the protruding portion 33a. Since it is formed integrally with the protruding portion 33a so as to be openable and closable, the box constituent member 33 can form the small storage chamber 45 alone, increasing the storage capacity without increasing the number of parts, and the storage box The degree of freedom of the overall shape of 31 can be increased.

  A first leg 58 is provided at the bottom of the box body 32 and extends toward a second cross member 56 that forms a part of the body frame F and is disposed below the storage box 31. A second leg 59 that houses 58 and extends toward the second cross member 56 is provided at the bottom of the box constituting member 33, and the second leg 59 is placed on the stay 57 of the second cross member 56. Since the box body 32 and the box component member 33 are supported by the second cross member 56 at the same location, the number of parts can be reduced as compared with the case where they are supported at positions separated from each other. .

  Further, when the storage box 31 is assembled and assembled to the vehicle body frame F, a step of fixing the box component member 33 to the vehicle body frame F, a rear portion of the pair of left and right upper down frames 15, a pair of left and right seat rails 17,. And a step of assembling the storage box 31 by attaching a box component 33 to the box main body 32 disposed between the pair of left and right rear frames 20 from the side, and the box main body 32 of the storage box 31 after assembly to the vehicle body frame F. The box mounting member 33 is attached to the box body in spite of the fact that the box structural member 33 overlaps with the upper down frame 15 and the seat rail 17 paired on the left and right in plan view. 32 and the storage box 31 is configured. Can be assembled to pay box 31 to the vehicle body frame F, it is possible to improve the assembling workability.

  In addition, the box component member 33 is provided with a notch 66, and when executing the step of attaching the box component member 33 to the box body 32, the battery 36 and the fuse box 37 to be accommodated in the electrical component storage chamber 35. The box constituent member 33 is attached to the box body 32 so that the electric wires 67 are sandwiched between the notch portion 66 and the box body 32 in a state where the electric wires 67. Compared with the case where a through hole through which the electric wires 67 are passed is provided in either the box body 32 or the box component 33, the operation of leading the electric wires 67 from the storage box 31 is facilitated and the arrangement layout of the electric wires 67 is increased. Can increase the degree of freedom.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the present invention described in the claims. It is.

For example , in the above-described embodiment, the box component member 33 is attached to the box body 32 after the box component member 33 is fixed to the vehicle body frame F. On the contrary, after the box body 32 is fixed to the vehicle body frame F, The box component 33 can be attached to the box body 32.
