A solution to reduce the ratcheting sound that occurs at the start of braking when an operation pedal is operated by foot. Because a mounting seat as a flat part and base plate are provided between a ratchet member and support axial center S of an operation pedal, there is a possibility that the ratchet member's vibration will propagate to the adjacent mounting seat and base plate, amplifying the ratchet sound. However, the adjacent mounting seat and base plate are provided with beads, having cross-sections that bend convexly in a direction substantially orthogonal to the vibration waveform of the ratchet sound produced by a pole coming into contact with serrations when the mounting seat and base plate maintain a flat plate shape; i.e., in a circumferential direction about support axial center S. Therefore, rigidity against the vibration is increased, propagation of vibration is minimized, and ratchet sound is effectively reduced.
