<P>PROBLEM TO BE SOLVED: To solve such problems that a foot board of a drum pedal for use in a drum performance having a flat surface comes into contact with a foot sole at a wide area and disperses force when the foot depresses it; and that the movement of an entire leg is easily guided into the vertical movement and the consecutive performance causes the fatigue of the leg. <P>SOLUTION: The foot board of the drum pedal is provided with a protrusion. The foot board comes into contact with the sole at a point by the operation of the protrusion to efficiently transmit the force in depressing. The contact with the sole is a point by the operation of the protrusion so as not to restrict the movement of the entire leg and prevent the fatigue. <P>COPYRIGHT: (C)2012,JPO&INPIT |
