ストが高くついている。 In motorcycles, steel pipes are appropriately welded and connected to form a frame. Mounting brackets are welded to the frame at predetermined positions in order to attach steps and mufflers for the driver and passengers to the left and right lower portions of the frame. Therefore, there are many parts to be welded, and gas welding is labor-intensive and increases manufacturing costs.

この考案は、かかる点に鑑み改善したもので、
以下本考案を図面に示す実施例について説明す

て連結する。 FIG. 1 shows an embodiment of the present invention, in which the rear portions of the left and right upper tubes 1 of the frame and the rear lower portions of the left and right down tubes 2 are connected by a reinforcing body 3.
The reinforcing body 3 may be manufactured from a light alloy by die-casting or the like, and the arm portion 4 is integrally provided so as to protrude from the bottom and rear of the reinforcing body 3. The arm portion 4 is provided with screw holes for screwing the driver's step 5, the passenger's step 6, and the muffler 7, and the driver's step 5, the passenger's step 6, and the muffler 7 are attached to the screw holes. do. Further, at the top end of the reinforcing body 3, there are two protrusions 3 that are spaced apart from each other in the front-rear direction and protrude upward.
a, 3a are integrally formed, and these projections 3a, 3a
is connected by bolts 8 to brackets 9, 9 projecting downward from the rear of the upper tube 1, and the top end of the reinforcing body 3 forms a stand grip 10, and the lower part of the reinforcing body 3 It is fastened and connected to the bracket 9 provided on the down tube.

を低減できる。 Therefore, the reinforcing body 3 can be made lightweight by being cast from a light alloy, thereby reducing the weight of the vehicle body. By providing the arm portion 4 on the reinforcing body 3, the driver step 5, passenger step 6, and muffler 7 can be connected to the arm portion 4.
Therefore, the number of brackets connected to the left and right down tubes 2 by welding can be reduced, and manufacturing costs can be reduced.

ない。 As explained above, this invention provides a reinforcing body that connects the rear portions of the left and right upper tubes and the rear lower portions of the left and right down tubes, and integrally provides an arm portion that projects downward and rearward on the reinforcing body. driver steps,
A passenger step and a muffler are attached to the reinforcing body, and two protrusions are formed on the top end of the reinforcing body so as to be spaced apart in the front-rear direction and protrude upward;
Both protrusions were connected to a bracket projecting downward from the upper chew, and the top end of the reinforcing body formed a stand grip. By casting the reinforcing body from a light alloy, the arm part It can be manufactured easily, the weight of the vehicle can be reduced, and the need for brackets to be welded to the vehicle body can be reduced, and welding work, which is expensive to manufacture, can be reduced, resulting in cost reduction. Further, the reinforcing body serves as a strength member of the vehicle body and can increase the strength of the rear part of the vehicle body, and since a stand grip is formed by the top end of the reinforcing body, there is no need to attach a special stand grip.
