摘要： A bass pad includes a frame body, a pad body, and a leg-opening mechanism. The frame body includes a pad base and a main post. The pad base is fixed to a clamp of a pedal device. The main post is arranged integrally with the pad base. The leg-opening mechanism includes two legs, two stays, and a sliding member. The height and angle of the pad base are adjusted by moving the sliding member in an axial direction of the main post to open or close the legs and the stays with respect to the main post.

摘要： A cam assembly includes a wheel member fixed to a shaft and a cam member removably attached to the wheel member. By attaching the cam member to the wheel member while arranging the cam member in a first orientation, a first cam shape is given to the cam assembly. Moreover, by attaching the cam member to the wheel member while vertically inverting the cam member to set the cam member in a second orientation, a second cam shape different from the first cam shape is given to the cam assembly.

摘要： A pedal device includes a switching device, which is capable of selectively switching the position of a spring between a use position, at which the spring is disposed during the use of the pedal device, and a non-use position, at which the spring is disposed during the non-use of the pedal device. The switching device is configured such that the length between a first end and a second end of the spring when the spring is disposed at the non-use position is less than the spring length when the spring is disposed at the use position.
