Description

  The present invention relates to a pedal device for performing a drum performance by performing a stepping operation with a foot.

  There is a bass drum pedal as a pedal for striking the drum head surface of a bass drum placed on the floor. This bass drum pedal is operated by depressing the pedal with one foot. When this pedal depression operation is performed, for example, a beater (striking member) connected to the arm pops out forward of the pedal device and strikes the drum head surface. In a drum system having a hi-hat pedal and a bass drum pedal, a single foot is placed on each pedal. Therefore, a bass drum pedal is placed on the right side plate and a hi-hat pedal is placed on the left side plate, and the plate beater is configured to be at the front end of the foot plate of these pedals. There has been proposed a drum foot pedal that enables the other foot to move freely (see, for example, Patent Document 1).
