ABSTRACT:
A foot pedal for a drum set such as a bass drum is constructed using a pedal frame which contains a frame body and two support members. Herein, the two support members project upwardly from both ends of the frame body. A rotation shaft is rotatably supported by beating portions which are provided at upper end portions of the two support members respectively. A foot board is provided for the pedal frame and is operated in response to step force applied thereto. A rocker is fixed to a selected position of the rotation shaft and is equipped with a beater by means of a beater rod. So, when a person depresses the foot pedal by a foot, step force applied to the foot pedal is transmitted to the rocker by means of a step force transmission member such as a chain, so that the rocker rotates together with the rotation shaft. In response to rotation of the rocker, the beater strikes a drum head of the bass drum. A spacing member links lower ends of the bearing portions together beneath the rotation shaft so as to reinforce the two support members. Thanks to provision of the spacing member, it is possible to prevent flexure from occurring on the support members in a horizontal direction when the foot board is depressed. Further, a cutting channel is formed to partially cut the rocker. The cutting channel has an arc-like shape formed about a center of rotation of the rocker so as to avoid interference between the rocker and spacing member while the rocker rotates.
