摘要： In a reciprocating-type electric shaver, an inner blade has an attachment groove which is open downward in a lower end of a side edge. An inner peripheral portion of the attachment groove has an engagement groove which is recessed in an in-plane direction on a wall surface of the side edge and in a longitudinal direction of the inner blade. An inner blade base has a projection at a position corresponding to the attachment groove. The projection can be elastically deformed in the in-plane direction on the wall surface of the side edge and in the longitudinal direction of the inner blade, and is formed so that an engagement claw disposed in a distal end of the projection can enter and engage with the engagement groove. The engagement claw engages with the engagement groove, thereby causing the inner blade to be fixed to the inner blade base.

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.

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 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 small blade is formed so that an inner blade base plate is partially erected, and is disposed in at least two rows on a circumference close to an outer periphery and on a circumference close to an inner periphery. There is provided a movable inner blade that has a movable small blade which is vertically movable along a front end surface in a rotation direction of the small blade, with respect to the predetermined small blade.
