摘要

A shaving sound generating element (70) has a vibrating element (71) that is projected from connection base (61) and elastically deformed when a blade (50) is resiliently deformed. A clamp (100) couples the vibrating element with blade, and includes clamping surfaces (111,121) arranged facing each other. The clamping faces have raised portions (112,122) to contact and press the blade, and non-raised portions (113,123) to stay out of contact with blade or to press blade with weak force. The raised and non-raised portions are arranged in extending direction (DZ) of blade.
