Abstract
A pedal device for a drum includes a base plate, a pedal, a chain, a pivot shaft, a beater, and an extension coil spring. When the pedal is freed from a depressed state, the urging force of the extension coil spring returns the beater from an operation position to a suspended position and returns the pedal to a standby position. A compression coil spring is arranged between the pedal and the base plate.
