にすることを目的とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adjustment device for adjusting the tension of a drive chain that drives the rear wheel of a motorcycle. The purpose is to simplify the structure by also serving as a rotation stopper when tightening.
従来、後車輪の組立や駆動チェーンの調節のたおり、不

The unique feature is that the tensioning direction of the cam member and the tightening direction of the rear axle are made to coincide with the tightening direction of the nut.
以下、これを図示の実施例によって説明する。This will be explained below with reference to illustrated embodiments.

いる。In the figure, l is a rear arm that supports the rear wheel of a motorcycle so as to be able to swing up and down by means of a shock absorber 1a, and an axle groove 2 that opens rearward is formed at the rear end. Reference numeral 3 designates a bottle protruding from the front of the axle groove 2, and together with a cam member 5 welded to the axle 4, constitutes a chain puller A. That is, when the cam member 5 is rotated clockwise in the drawing, its cam surface 5a presses the bottle 3, and the reaction force moves the rear axle 4 rearward, thereby tensioning the drive chain. There is.

、部品点数が少なく、作業が容易であり、特に流れ作業
で組立を行う場合に有利である。Therefore, after the adjustment of the chain is completed, the cam member 5 is in contact with the pin 3, and the axle 4 welded to it is also prevented from rotating, so there is no need to prevent rotation when tightening the nut 6. . Further, when assembling the rear wheel, since the axle 4 and the cam member 5 are integrally connected, the number of parts is small and the work is easy, which is particularly advantageous when assembling is carried out on assembly lines.

る効果がある。As described above, this invention forms an axle groove that opens rearward at the rear end of the rear arm, and uses a chain puller consisting of a bottle protruding in front of the axle groove and a cam member supported by the axle to drive the drive chain. In a two-wheeled motor vehicle, the cam member and the axle are fixed by welding, and the direction of tension of the cam member and the tightening of the rear axle are made to match the direction of tightening of the rear axle. Therefore, compared to installing a bottle or screw to the rear end of the rear arm to prevent the axle from being pulled out, there are fewer parts and the work is easier, and when assembling the rear wheel, the rear axle can be tightened with a NAND. At this time, the cam member integrally formed with the rear axle is prevented from rotating by the pin, which has the effect of making the work easier.
