ABSTRACT:
A spring holding mechanism is adapted to a foot pedal including a spring which applies a tensile force to a rotation shaft interconnected with a drum beater of a bass drum. It includes an external thread (i.e. a bolt) interconnected to one end of the spring, a support member having a hole allowing for the external thread running therethrough, and an internal thread (i.e. a fixing nut) that is engaged with the external thread so as to fix the support member in position, thus limiting the vertical movement of the external thread in an axial direction. A projection and a recess are formed in the support member and the internal thread respectively. The projection having an external slope is engaged with the recess having an internal slope so that the projection is received inside the recess when the internal thread is attached to the support member.
