たことを特徴とする二輪車のスイングアーム。 In a swing arm in which an end plate is fitted into a fitting hole formed at the rear end, the tip edge of the end plate has a shaft insertion hole that penetrates from the vehicle surface to the outside surface of the vehicle, and the base edge A contract-shaped shaft support is provided protruding from the outer surface of the vehicle at the section, and the circumferential surface of the proximal edge of the plate including the shaft support is formed to be substantially the same as the inner circumferential surface of the fitting hole, and a part of the circumferential surface is formed. The end plate is press-fitted into the fitting hole by forming the circumferential surface into a conical tapered surface so that the portion that makes sliding contact with the opening edge of the fitting hole during fitting is larger than the proximal end. Features a two-wheeled vehicle swing arm.
