Claim:
An adjusting mechanism of an instrument pedal, comprising: a pivotable shaft rotatably supported by a base, the pivotable shaft having at least one fixing hole formed therein; a drumstick coupled to the pivotable shaft for angular displacement therewith; a foundation coupled to the pivotable shaft for rotative displacement therewith, the foundation having (a) a pivot hole receiving the pivotable shaft therein, (b) an arc surface formed around a perimeter portion of the foundation, and (c) a radially directed sliding groove formed in the arc surface, the sliding groove being disposed in correspondence with the fixing hole; a fixing element passing through the sliding groove connects to the fixing hole on one end thereof, an opposing end portion of the fixing element being disposed in contiguous contact with the arc surface on opposing sides of the sliding groove to affix the adjusting mechanism to the pivotable shaft; and an instrument pedal having a distal end coupled to the foundation by a connecting element extending therebetween for rotation of foundation responsive to angular displacement of the instrument pedal to thereby angularly displace the drumstick.
