The inside of the rubber elastic body 2 2 0 forming such a contour shape is provided with three holes of various shapes penetrating in the width direction, and oblong holes 2 2 0 b are formed in order from the front side (corresponding to the box 1 5 Long hole 1 5 t), deformed long round hole 220c, deformed round hole 220d, and a long hole 2 2 0 e ° extending through the back is formed at the base of the protrusion 2 2 0 a as shown in Figure 2 8. · The elastic body 2 2 0 contained in the box 15 is the left and right sides 2 2 0 L, and the 2 2 0R contacts the side wall 1 of the box 15 at the front, that is, by one of the stops of the stopper 17. There is a gap between 5 a and the lid member 16 ′, as they are gradually moved away from the side wall 15 a and the lid member 16 of the box 15 toward the rear. As described above, the elastic body 2 20 is formed in the stopper piece 17 to block the front portion and the rod 10 to the rear portion to form a simple structure interposed between the front fork 8 and the rod 10. When the front wheel 13 is bumped by the ground or a load is applied to brake the rocker arm 9 to shake, as shown in FIGS. 29 and 30, the rocker arm 9 and the rod 10 integrated with the arm are rocked. The 10 series is elastically deformed by pushing the elastic body 220 toward the front fork 8 side. · When the elastic body 2 2 0 is pressed, it expands in a direction at right angles to the pressing direction, that is, upwards, downwards, and left and right directions. The left and right expansion systems bulge the left and right sides 2 2 0 L, 2 2 0 R and the side walls 15 a of the box 15 and the cover member 16 are respectively prevented from forming an expansion. As the pushing is performed, the contact area also increases, which increases the sliding resistance of the contact surface.

The load characteristic of stroke-stroke is a hysteresis curve. When the stroke is small, the starting action forms a curve with small sliding resistance and gentle inclination. When the impact is large and the sliding resistance is applied together with the elastic force, the increase of the load becomes rapid. The effect of progressively increasing sliding resistance and the increase in the load increase ratio also indicate that the sharp increase and steepness of the curve can improve the attenuation effect. Changing the shape of the left and right side surfaces 220L, 220R of the elastic body 220 can easily change the effect of the sliding resistance, so that the stroke-load characteristic can be easily set to a desired characteristic.
