Utilizing the characteristics, the cylindrical space formed by the inner surface of the housing, the end surface of the bearing bush, and the outer peripheral surface of the bolt is formed of a thermoplastic synthetic resin selected from polyolefin resin or polyester resin in the cylindrical housing. By arranging the intermediate bearing with a compressive load applied, the frictional resistance is large in the speed range (high speed) of high-frequency micro-vibration generated from the vehicle body or the engine, and the micro-vibration is absorbed, and the speed range during pedal operation is increased. At low or medium speeds, the frictional resistance is small and smooth pedal operation is possible. It is possible to remove the discomfort caused by the high-frequency micro-vibration.
