Abstract:
[Problem] To provide a rotary shaver with which it is possible to cut beard suitably. [Solution] The present invention provides a rotary shaver 1 in which an outer blade 10 has a blade tip at the lower end of an inner wall of each of a plurality of slits 11, and an inner blade 20 includes a disc-shaped base 21 and a plurality of small blades 22 protruding from the base 21 toward the outer blade 10. A blade tip 23 of each of the plurality of small blades 22 has a shape which is curved inwardly of an upper surface 22a of each small blade 22. Each of the plurality of slits 11, when viewed in a rotating direction of the inner blade 20 with respect to the outer blade 10, has a shape which is inclined with an outer end positioned forwardly of an inner end, and which is curved so as to bulge backward in the rotating direction with a radius of curvature greater than that of the blade tip of each of the plurality of small blades 22. Each of the plurality of small blades 22 has a shape obtained by forming a groove in the base 21 and then bending the root of a resultant projection in a direction opposite to the rotating direction.
