摘要
A rotary electric shaver according to the present invention includes an outer blade whose upper surface functions as annular shaving surfaces having multiple hair inlets formed therein, and an inner blade that has a small blade which rotates while coming into sliding contact with a lower surface of the outer blade. The inner blade is an integral structure using a metal material, and has a projection in which an upper surface side is a convex portion and a lower surface side is a concave portion at a center position in a radial direction. An upper end portion of an inner blade drive shaft directly engages with the concave portion so as to be disengageable therefrom.
