Abstract
A drum foot pedal apparatus includes: a coil spring imparting resilient self-returning force to a foot board; a rod member (or an adjusting bolt) supported by a support section provided on a support post member; and a tension adjustment mechanism provided between the coil spring and the rod member. The tension adjustment mechanism includes a connection position adjustment section that interconnects the lower end of the coil spring and the rod member above the support post member, and that is constructed to permit adjustment of a connection position between the lower end of the coil spring and the rod member or the adjusting bolt at a position above the support section. Thus, it is possible to effectively prevent frictional wear of component parts and generation of noise and achieve an enhanced operability in the tension adjustment, with a simple construction having a minimized number of component parts.
