This configuration allows head to swing about the two axes, and thus head easily follows undulations of skin. Head is movable up and down with respect to body, and thus head sinks with respect to body when head is strongly pressed against the skin. The aspect provides electric shaver that has a high follow-up performance of head swinging according to undulations of skin and hardly irritates the skin strongly.Type: GrantFiled: November 12, 2015Date of Patent: September 11, 2018Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Hiroaki Shimizu, Yasuhide Matsuoka, Toshio Ikuta
