As a prior art, there is Jitsukai Sho 61-25292.

(Object of the Invention) An object of the present invention is to enable the lower part of the side cover to be fixed by a key lock device using a step supporting stay, thereby reducing the number of parts and facilitating assembly.

(Technical Means for Achieving the Purpose) In order to achieve the above-mentioned object, the present invention has a step support stay fixed to a vehicle body frame, in which a lock shaft insertion hole is formed, and a key lock device main body is provided under a side cover. The lock lever is attached to the lock shaft that is rotatably supported by the main body of the key lock device, the lock lever is inserted into the insertion hole, and the lock lever is engaged with the back surface of the step support stay to open the side cover. It is fixed to the step support stay.

(Embodiment) FIG. 1 is a partial left side view of a motorcycle to which the present invention is applied. In FIG. 1, a lower frame 2 extending downward and frontward is provided at a rear end portion of a rear frame 1. They are welded, and the front end portions of the rear frame 1 and the lower frame 2 are fixed to a front frame (not shown). Rear frame 1
The seat 3 is supported on the upper part of the rear part, the lower frame 1,
A rear cover 6 is fixed to the rear part of the bolt 2 by bolts 9 and the like, and a rear fender 7 extending rearward and downward is also fixed. A bracket 15 is welded to the front portion of the lower frame 2, and an aluminum alloy step support stay 12 is fixed to the bracket 15 by a pair of front and rear bolts 16.
A step 13 is supported at the lower end of the support stay 12 so as to be stored (rotatable).

A pair of left and right side covers 10 is provided so as to extend from the front edge portion of the rear cover 6 to the lower rear portion of the fuel tank 5, and covers the battery 17 and various electric components from the side. The side cover 10 has a rear end portion and a front upper end portion which are fixed to the rear cover 6 and the fuel tank 5, respectively, by utilizing the grommets 21 and 26 and the projections 22 and 27, and the front lower portion is step-supported by the key lock device 20. Stay 12
It is fixed to.

The details of each mounting portion of the side cover 10 will be described.
The figure is a cross-sectional view of the rear mounting part (VV cross-sectional enlarged view of FIG. 1)
The annular grommet 21 is fitted into the hole formed in the front end vertical wall 6a of the rear cover 6, while the side cover is
A bulge-like projection 22 protruding rearward on the rear end vertical wall 10a
Are integrally formed, and the rear end of the side cover is fixed to the rear cover 6 by press-fitting the protrusion 22 into the grommet 21.

FIG. 6 is a cross-sectional view of the front mounting portion (VI-VI cross-sectional enlarged view of FIG. 1), in which a bracket 25 extending downward is welded to the bottom plate of the fuel tank 5, and an annular shape is formed in the hole of the bracket 25. Grommet 26 is fitted. On the other hand, the protrusion 27 is formed on the rear surface of the side cover 10 so as to project inward of the vehicle body.
It is fixed to the fuel tank 5 by pressing 27 into the grommet 26.

FIG. 2 shows an enlarged side view of the upper part of the step support stay alone. A seating surface 31 is formed on the upper end of the stay 12 so as to project upward between the bolts 16 through a step portion 30.
A lock shaft insertion hole 32 is formed in 31. The insertion hole 32 has a partially circular shape in the first half and a lever insertion extension 32a extending rearward in the latter half.

FIG. 7 is a side view of the side cover 10 where the key lock device is mounted. The side cover 10 has a lock device body mounting hole.
35 is formed in the mounting hole 35 to prevent the device body from rotating.
A pair of linear portions 35a is formed.

FIG. 3 is an enlarged view taken along the line III-III of FIG. 1, in which the lock device body 36 is formed in a cross-sectional shape (both side cutouts) corresponding to the shape of the mounting hole 35 and has a male screw portion 36a. Then
It is fixed to the side cover 10 by being inserted into the mounting hole 35 from the outside of the vehicle body so as not to be rotatable and by screwing a main body fixing nut 40 from the rear surface of the side cover. A rubber sheet 41 is fitted on the outer circumference of the front end of the male screw part 36a. Lock shaft 43
Is rotatably supported by the lock device body 36 and extends inward of the vehicle body. A lock lever 45 is fixed to the vehicle body inner end by a screw 39. It is rotated in the range of 90 degrees. An engagement surface 47 with which the lever 45 is engaged is formed on the back surface side of the seating surface 31, and an eaves portion 48 that covers the lever 45 is formed on the outer peripheral portion of the engagement surface 47 via a step portion 50. ing.

FIG. 4 is a view (back side view) taken along the line IV in FIG. 3, and the position of the lever 45 shown by the solid line (upward position) is the lock position,
The position of the lever 45 (rearward position) indicated by a virtual line is the release position. At the release position, the lever 45 can be taken in and out from the hole extension 32a. Further, of the engaging surface 47 in the range of approximately 90 degrees, in the range of the angle α1 from the release position side, it is an inclined surface that projects toward the inside of the vehicle as it goes to the arrow A1 side. In the range of, the maximum constant overhang (thickness) is maintained.

FIG. 8 is a side view of the rubber sheet 41, and has a hole 52 having substantially the same shape as the lock device main body mounting hole 35 of FIG.

A method of attaching the side cover 10 and the like will be described. First, the projection 22 at the rear end of the side cover shown in FIG. 1 is inserted into the grommet 21 of the rear cover 6, and then the projection 27 at the front end is inserted into the grommet 26 of the bracket 25 of the fuel tank 5 on the inner side of the vehicle body.

Then, the lock shaft 43 and the lever 45 in the released state are inserted into the insertion hole 32 of the stay 12 as shown by the phantom line in FIG. 4, and the lock shaft 43 is rotated in the arrow A1 direction with the key inserted into the lock device body 36. To do. Thereby, the lever 45 engages with the engagement surface 47, and the lower portion of the side cover is fixed to the stay 12.

In the process of rotating the lever 45 in the A1 direction, the angle α1
Due to the inclination of the engaging surface 47 of the portion, the tightening force becomes stronger as the member rotates, and the rubber sheet 41 is compressed.

(Other Embodiment) Instead of fixing the front part and the rear part of the side cover by a plug-in type using a grommet as in the above-mentioned embodiment, it is also possible to attach with a bolt or the like.

As described above, according to the present invention, the step support stay is formed with the lock shaft insertion hole, and the hole and the back surface of the support stay are engaged with the main body of the key lock device provided under the side cover. Since it is used as a combination member, it is not necessary to specially provide an engagement member, a bracket, etc., exclusively for the key lock device, on the vehicle body frame, etc., and the number of parts can be reduced, the cost can be reduced, and the assembling can be facilitated. .
