Abstract
Disclosed are a drum beater and a drum foot pedal apparatus which are simple in construction with reduced numbers of component parts and yet allow weight adjustment of the beater to be performed promptly and reliably through a mere manual operation without using any tool, and which include: a beater head for striking a drum; a beater rod having the beater head mounted thereon; a retention member mounted on the beater rod, through a mere manual operation without using any tool, in such a manner that it is axially displaceable relative to the beater rod; a spring normally biasing the retention member toward the beater rod; and a weight member held sandwiched between the retention member and the beater head by the biasing force of the spring.
