[0021]
The rear frame 20 is a pipe having a rectangular cross section, and a box-shaped connecting block 201 is fixed to the rear end thereof by welding. The connecting block 201 has an upper mounting plate 201a and a lower mounting plate 201b. Each mounting plate 201a, 201b has a bolt hole (described later) and nuts 201c, 201d welded to positions corresponding to the bolt hole. Is provided. Further, on the lower mounting plate 201b, corresponding to the bolt holes, a sleeve (described later with reference to FIG. 3) for guiding the bolts 48 passed through the bolt holes is integrally formed by welding or the like.
[0022]
A second rear fender 46 that covers the upper portion of the rear wheel 37 is disposed along with the first rear fender 41 at the lower portion of the rear frame 20. The rear end of the rear fender 46 is formed horizontally to constitute a mounting portion 461.
[0023]
The reflector 401, the rear frame 20, and the second rear fender 46 are covered with a rear body cover 7, and mounting portions 71 and 72 are formed on the rear body cover 7 so as to project inwardly. .
[0024]
The members configured as described above are coupled to each other by fastening with bolts and nuts. That is, the mounting portion 71, the horizontal member 404, and the upper mounting plate 201a are coupled to each other by fastening the bolt 47 and the nut 201c, and the lower mounting plate 201b, the mounting portions 461, 411, and the mounting portion 72 are connected to the bolt 48. And the nut 201d are coupled to each other by fastening. In addition, buffer members 49 and 50 made of an elastic material such as rubber are interposed between the members connected by bolts and nuts.
[0025]
FIG. 3 is a cross-sectional view showing details of the connecting portion by the bolt and nut, particularly the connecting portion by the bolt 48 and the nut 201d. A sleeve 51 is formed integrally with the lower mounting plate 201b. The sleeve 51 guides the bolt 48 to the nut 201d on the inner surface, and guides or holds the buffer member 50 on the outer surface. The length of the sleeve 51 is determined so that at least the tip of the sleeve 51 is not exposed from the buffer member 50 when the buffer member 50 is passed through the sleeve 51.
[0026]
On the other hand, a sleeve 52 with a flange is fitted on the mounting portion 72 side of the rear body cover 7. Unlike the sleeve 51, the sleeve 52 is not fixed to the rear body cover 7 in advance, but after the rear body cover 7 is positioned at a predetermined position with respect to the buffer member 50 so that the bolts 48 pass, The mounting portion 72 is inserted and inserted into the buffer member 50.
[0027]
The buffer member 50 is fitted in advance to the mounting portion 411 of the first rear fender 41, that is, the member 411 protruding horizontally. Thus, when the bolt 48 is screwed into the nut 201d and fastened, the ends of the sleeves 51 and 52 abut against each other, and the interval between the flange portion of the sleeve 52 and the lower mounting plate 201b is fixed. On the other hand, the mounting portions 461, 72, and 411 can move along the outer periphery of the sleeves 51 and 52 within the range of elastic deformation of the buffer member 50.
[0028]
Next, the operation by limiting the length of the sleeve 51 so that the tip is not exposed from the buffer member 50 will be described. 5A shows the case where the tip of the sleeve 51 is not exposed from the buffer member 50. FIG. 5B shows the tip of the sleeve 51 protruding from the buffer member 50, and the outer periphery of the sleeve 51 is connected to the mounting portion 72. It is a figure which shows the case where it was made to engage. When the sleeve 51 is shortened, first, the attachment portion 461 is attached along the outer periphery of the sleeve 51, and then the buffer member 50 integrated with the protruding portion 411 is attached along the outer periphery of the sleeve 51. Next, the mounting portion 72 of the rear body guard 7 is moved in the direction of arrow h, and the sleeve 52 is fitted in the direction of arrow v with the hole 72a aligned with the hole 50a of the buffer member 50.
[0029]
In contrast, in the example of FIG. 5B, when the rear body cover 7 is moved in the direction of the arrow h and the attachment portion 72 is assembled, the attachment portion 72 is attached to the tip of the sleeve 51 protruding from the buffer member 50. Will hit. Therefore, in order to avoid this, it is necessary to bend the mounting portion 72 in the direction of the arrow b as shown by the dotted line in FIG.
[0030]
As shown in FIG. 5A, when the sleeve 51 and the sleeve 52 are divided, the mounting portion 461 and the buffer member 50 can be easily assembled to the lower mounting plate 201b using the sleeve 51 as a guide means. Can do. Since the rear body cover 7 can be mounted without bending, the operation is simple. In the above, one side surface of the vehicle body has been described, but the structure of the connecting portion is common to the left and right sides of the vehicle body.
[0031]
As described above, in the present embodiment, the first rear fender 41, the second rear fender 46, the rear frame 20, and the rear body cover 7 that are molded integrally with the reflector 401 are provided on the left, right, and top of the vehicle body. The four joints were joined by fastening bolts 47 and 48 and welding nuts 201c and 201d provided on the rear frame 20. That is, a plurality of members can be assembled together with a small number of coupling portions by so-called co-fastening. Further, by combining a sleeve 51 formed integrally with the rear frame 20 and a sleeve 52 attached separately, the assembly can be advanced while each member is sequentially temporarily assembled around the sleeve 51.
[0032]
