Abstract: One aspect of the rotation stopper (1) for the cymbal pad (10) has a holding hole (19) provided in a holding plate (18) of the cymbal pad (10) and a holding sleeve (22) provided on a supporting rod (20) of a cymbal stand. The holding sleeve (22) is arranged to be inserted through the holding hole (19) with an amount of play in the fitting. The holding hole (19) has a plurality of engaging recesses (34) on the inner periphery. The holding sleeve (22) has an outer peripheral surface having at least one ridge (33) that engages with at least one of the engaging recesses (34) so as to deter the cymbal pad (10) from rotationally moving relative to the holding sleeve (22).
