挿通して、左右の後ホークＣの前端を軸着している。(Prior art and its problems) In O1-Pie, the front ends of the left and right rear forks are pivoted to the left and right shaft holes of the frame, and the cushion unit is extended and contracted to allow the rear forks to swing. The rear wheels are rotatably supported on axles attached to the rear ends of the left and right rear forks so that the rear wheels can be cushioned.
As shown in the figure, the shaft barrels of the front ends of the left and right rear forks C are arranged on both outsides of the shaft hole B provided in the frame 8, and the front ends of the left and right rear forks C are inserted through the support shafts. It is attached to the shaft.

３０９０号公報参照。In this case, lJ of the left and right frames A becomes narrower, resulting in insufficient rigidity against torsion. Moreover, if an attempt is made to increase the rigidity by increasing the width of the left and right frames, there is an inconvenience that total 1] becomes larger. The shaft holes of the left and right frames are placed on the outside of the shaft cylinders at the front ends of the left and right rear forks, and the positions of the shaft holes and shaft cylinders are swapped. Although this increases the rigidity, the overall width increases, which is disadvantageous. For example, Utsukai Showa 62-4. ．．

の後輪懸架装置を得ることを目的とする。This invention secures the left and right frame width, increases rigidity, and reduces the hit of the shaft part of the front end of the rear hawk.
The purpose of installing the left and right steps is to obtain a motorcycle rear wheel suspension system that does not increase the width.
以下、本発明を第１図及び第２図に示す実施例によって
説明する。The present invention will be explained below with reference to the embodiments shown in FIGS. 1 and 2.

支承する。The frame 1 has a pair of left and right central parts, and a shaft hole 2.
is the provision. The left and right rear forks 3 have a shaft tube 4 welded to their front ends. The front part of the right rear fork 3 is bent inward. The left hawk 3 is designed so that the driving shirt l-6 that drives the rear wheel 5 passes through the inside thereof. This type of motorcycle is called a shaft drive type, and the rear wheel is driven by a drive shaft 6 via a bevel gear. The shaft tube 4 at the front end of the right rear fork 3 is disposed between the left and right shaft holes 2, and the shaft tube 4 of the left rear fork 3 is disposed outside one of the shaft holes 2. Then, the support shaft 7 is passed through the two shafts n4 and the two shaft holes 2 and fastened. A bearing 8 is interposed between the support shaft 7 and the shaft hole 2, so that the left and right rear forks 3 can rotate. Left and right rear hawk 3 and frame 8-
A cushion unit 9 is connected between the rear parts of the arm 1, and the rear fork 3 can be made into a rocking cushion by expanding and contracting the cushion unit 9. An axle 10 is attached to the rear ends of the left and right rear forks 3, and a rear wheel 5 is rotatably supported on the axle 10.

付は巾を小さくできて、乗車姿勢もよくできる。Between the left and right shaft holes 2 of the frame 1, there is one rear fork 3.
Since the rear fork 30 and the other shaft cylinder 4 are arranged outside one of the shaft holes 2, the width of the left and right frames 1 in which the left and right shaft holes 2 are provided can be expanded. As a result, the torsional rigidity of the frame 1 can be increased, resulting in a high strength frame. Moreover, the width of the left and right rear forks 3 can be made close to that of the left and right frames 1, and the overall width can be made small. For this reason, the lower part 11 of the frame 1 can be made narrower as a whole, and the mounting position such as the foot step position can be made smaller, allowing for a better riding posture.

勢もよい乗り易いものにできる。As explained above, this invention arranges the front end shaft cylinder of one of the left and right rear forks between the left and right shaft holes of the frame, and the front end shaft cylinder of the other rear fork is placed outside of one shaft hole of the frame. The front end of the rear fork was pivotally attached to the two axle tubes and a support shaft inserted through the two axle holes, and the rear wheel was rotatably supported on axles provided at the rear ends of the left and right rear forks. Therefore, the width of the left and right frames in which the left and right shaft holes are provided can be increased, and the frame can be made to have high torsional rigidity and strength. Also, the size of the left and right rear hawks does not become too large, and the size of the hit can be reduced. This makes the inside of the vehicle narrow and the riding posture good and easy to ride.
