  According to the above configuration, in the model without the rear grip 22, the tail cover 20 of FIG. 1 is supported on the rear frame 2 via the bracket 24 that is detachably attached to the rear frame 2 of FIG. On the other hand, in the model with the rear grip 22 in FIG. 2, the rear grip 22 in FIG. 2 is attached to the rear frame 2 with the bracket 24 and the tail cover 20 in FIG. 1 removed. Thus, in the model with the rear grip 22, the tail cover 20 is unnecessary, and therefore it is not necessary to prepare separate tail covers for the model with the rear grip 22 and the model without the rear grip 22. Further, in the model having the rear grip 22, the tail cover 20 is not required, and thus the visibility of the rear grip 22 from the passenger is good.

  When the tail cover 20 is directly attached without using the bracket 24 of FIG. 1, it is necessary to provide an attachment portion (locking portion) on the rear cover body 14. In that case, when the tail cover 20 is removed, in the model with the rear grip 22, the mounting portion is exposed outward, which is not preferable in appearance. Further, if the tail cover 20 is bolted to the rear frame 2 without using the bracket 24, the bolt is exposed to the outside of the tail cover 20, which is not preferable in terms of appearance. In the above configuration, the tail cover 20 is attached to the rear frame 2 via the bracket 24, and the bracket 24 and the rear grip 22 shown in FIG. The tail cover 20 can be dispensed with in a model having the rear grip 22.

  Further, the bracket 24 and the grip 22 are attached to the rear frame 2 by a first screw body 46 penetrating the rear cover body 14. Thereby, the bracket 24, the tail cover 20 (FIG. 1), and the grip 22 can be attached and detached without removing the rear cover body 14.

  The fitting protrusion 40 of the tail cover 20 shown in FIG. 6 is fitted in the fitting hole 28a (FIG. 4) of the bracket 24. With such a fitting structure, the tail cover 20 can be easily attached to the bracket 24, and the bolts are prevented from being exposed to the outside of the tail cover 20, thereby improving the appearance of the motorcycle.

  Further, the insertion piece 32 at the rear end of the bracket 24 is inserted into the insertion recess 38 of the tail cover 20. As a result, the position of the tail cover 20 with respect to the bracket 24 is restricted, and the attachment of the tail cover 20 to the bracket 24 is further facilitated.

  Since the tail cover 20 is attached to the bracket 24 by the second screw body 54 shown in FIG. 7, the tail cover 20 is combined with the fitting structure of the fitting protrusion 40 and the fitting hole 28a shown in FIG. The support to the bracket 24 becomes strong.

  The present invention is not limited to the above-described embodiment, and various additions, modifications, or deletions can be made without departing from the gist of the present invention. Therefore, such a thing is also included in the scope of the present invention.
