ELECTRIC RAZOR

WIPO Patent Application WO/2014/155970

A1

An electric razor (1) is provided with a hair removal portion (20), a main unit portion (10) supporting the hair removal portion (20), and a vibration generation unit (100), including a magnetic force generating unit (110) and an output movable portion (120). The magnetic force generating unit (110) includes a coil (112) and an input-side core (113). The magnetic force generating unit (110) forms a magnetic field by way of the coil, and causes suction force of the input-side core (113) to be exerted on the output movable portion (120). The output movable portion (120) includes: an output-side core (125) which moves relative to the magnetic force generating unit (110) on the basis of the suction force of the input-side core (113); and a vibration component (121) which is coupled to the output-side core (125), and which conveys vibration to the hair removal portion (20) on the basis of the relative movement of the output-side core (125). The vibration generation unit (100) is configured so as to cause the output-side core (125) to approach the input-side core (113) as the load of the hair removal portion (20) increases.
