摘要： A reciprocating-type electric shaver includes an outer blade, an oscillator that is driven to reciprocate by a motor, and an inner blade that reciprocates in cooperation with the oscillator. The oscillator includes attachment portions that are respectively attached to a main body, a movable base, both end sides of which are supported by the attachment portions via support portions having a substantially U-shape, and a cooperation portion that cooperates with the inner blade. In the respective support portions, a portion on a side connected to the attachment portion in a base portion, which is one linear portion of the U-shape, is formed in flexible oscillating pieces. The respective oscillating pieces are formed to be tilted in a direction orthogonal to a reciprocating direction of the movable base so that a lower portion side of the respective oscillating pieces is open outward in the reciprocating direction of the movable base.

摘要： A rotary electric shaver with an outer cutter having a circular shaving top surface with numerous hair introduction openings and an inner cutter having a small cutter slidably rotating in contact with a bottom surface of the outer cutter. The rotary electric shaver includes an outer cutter set wherein the outer cutter is assembled in an outer cutter holding unit and an inner cutter set wherein the inner cutter is assembled in an inner cutter holding unit. The outer cutter set and the inner cutter set are respectively provided with a positioning convex portion on one and a positioning concave portion on the other. The positioning convex portion can fit in the positioning concave portion such that the outer cutter set can be assembled with the inner cutter set only in a case where the outer cutter set and the inner cutter set are in a predetermined assembly position.
