Abstract
Concave partstoformed on lower surfaces of radial partsare formed in a groove shape extending from the side of a central partof a bottom frametoward an outer peripheral side in a radial direction. Accordingly, the formation of ribs in the radial partsof the bottom frameis not required, or the number of ribs that are formed can be reduced, while the rigidity of the bottom frame(radial parts) can be secured by the concave parts. Thus, even in the case where the bottom frameis formed by using resin molding, the sink marks generated in the radial partscan be suppressed. Therefore, the bottom framecan be reinforced by the concave partsto, while the appearance of the percussion instrumentcan be improved.
