アームの軸受部構造。 A bearing structure for a pedal arm rotatably supported on a pedal bracket fixed to an inside panel facing each other at a predetermined distance. A synthetic resin bearing bush is provided with a flange at one end of each section, and a circular hole on the inner surface and a truncated conical recess that is continuous with the circular hole and widens toward the end. The housing is press-fitted in contact with the end surface of the housing, a bolt is inserted into the bearing bush, and the bolt is fixed between the pedal brackets, and the inner surface of the housing is inserted into the cylindrical housing. The space formed by the truncated conical recess of the bearing bush and the outer circumferential surface of the bolt is made of thermoplastic synthetic resin whose frictional resistance exhibits speed dependence, and the cylindrical surface portion and the end surface of the cylindrical surface portion are formed at the center of the outer circumference. Intermediate bearings each having integrally formed frustoconical surfaces tapering toward the ends have their cylindrical surfaces pressed against the inner surface of the housing, and the frustoconical surfaces wedge into frustoconical recesses of the bearing bushings. A bearing part structure of a pedal arm, characterized in that the bearing part structure is arranged so that a compressive load is applied to the inside thereof.
