等の不都合を伴う。 Conventionally, this type of device has a pair of square pipe-shaped rear forks arranged side by side on both sides of the rear wheel, and an internal collar having slits on both sides and a horizontal shaft hole at the tail end of each rear fork. We have proposed a type in which each end of the axle of the rear wheel is inserted and supported through the rear fork, and an adjustment bolt is provided between the collar and the end plate at the tail end of the rear fork. For example, as shown by a in Fig. 1, the head is engaged with the collar b side, extends longitudinally toward the rear end plate c side, and a nut d is attached to the outer end. In such a case, the bolt a must be relatively long, and when the bolt a is rotated so as to move the collar b backward to the right in the drawing, the bolt a will gradually move backward to the right in the drawing. It is accompanied by inconveniences such as protruding in the longitudinal direction and spoiling the appearance.

特徴とする。 The purpose of the present invention is to obtain a device free of such inconveniences, and a pair of square pipe-shaped rear forks 2 are arranged side by side on both sides of the rear wheel 1 on the left and right sides.
The tail end of each rear fork 2 is provided with slits 3, 3 on both sides for guiding the axle 7, and an internal collar 6 in which a shaft hole 5 for supporting the axle 7 is bored, and the rear fork 2 is attached to the collar 6. End plate 8 at the tail end of
In the device, a screw hole 10 is provided in the collar 6 in the front-rear direction so as to be offset downward from the shaft hole 5, and the adjuster bolt 9 is screwed into the screw hole 10. It is characterized in that the head of the bolt 9 is supported by the end plate 8.

する。 FIGS. 2 to 5 show one example of this, and in this case, the shaft hole 5 and the screw hole 10 are deviated upward and downward, respectively, with respect to the central axis XX of the rear fork 2. However, the present invention is not limited to this, and for example, as shown in FIG. 6, the shaft hole 5 may be aligned with the central axis XX, and only the screw hole 10 may be deviated downward with respect to the central axis XX. The axle 7 is provided with a nut 7a at its outer end, and a drive chain 11 is provided between the rear wheel 1 and an engine (not shown), and this point is not particularly different from the conventional one. Further, as clearly shown in FIG. 4, the bolt 9 is such that its enlarged head 9a is supported in contact with the back surface of the end plate 8, and is provided with a suitable rotation stopper 9b.
その作動を説明するに、アジヤストボルト９を
回動すれば螺孔１０を介してこれと係合するカラ
６はリヤフオーク２内を螺進螺退してこれに所定

ない。 To explain its operation, when the adjuster bolt 9 is rotated, the collar 6, which engages with it through the screw hole 10, is screwed back and forth inside the rear fork 2, and a predetermined adjustment is given to it. At this time, the length of engagement of the bolt 9 with the collar 6, that is, the length within the screw hole 10, is only adjusted, and the length of the bolt 9 protruding rearward does not change.

る。 In this way, according to the present invention, in the collar 6,
A screw hole 10 in the longitudinal direction is provided in the shaft hole 5 that supports the axle 7, and an adjustment bolt 9 is screwed into the screw hole 10, so that the head of the bolt 9 is attached to the tail end of the rear fork 2. The screw hole 10 provided below the shaft hole 5 is supported by the end plate 8 of the collar 6, so that the load from the running tire is not as great as the upper part of the shaft hole 5. The collar 6 can be miniaturized without reducing the tire adjustment stroke, and the screw hole 10 can be lengthened to lengthen the adjustment stroke of the tire. is shortened and the front and back length of the swing arm can be shortened.Furthermore, the protrusion length of the adjustment bolt 8 from the end plate 8 does not change when adjusting it, so it does not spoil the appearance. have an effect.
