A rotary electric shaver includes an outer cutter case secured to the outer periphery of an outer cutter and having a sliding surface formed on the outer periphery. An outer cutter case holder is fitted in a mounting port to vertically move with an upper limit position restrained and pivotably holds the outer cutter case to guide the sliding surface. A pushup plate imparts an upward return tendency to an outer cutter case assembly including the outer cutter, the outer cutter case and the outer cutter case holder. The outer periphery of the outer cutter case is provided with a projection extending to the upper surface of the outer cutter frame, serving as a stopper which prevents the outer cutter case from sinking into the mounting port. This arrangement prevents the outer cutter from being caught by the inner edge of the mounting port and improves shaving performance.

A raw garbage treatment apparatus including a treatment tank 10, a rotating shaft 32 which rises in an upright attitude from the center of the bottom of the treatment tank, a motor 36 which rotates the rotating shaft from beneath the treatment tank, a plurality of rotating blades 58 which have cutting vanes 58A that extend outward with the rotating shaft as the center and which are provided on the rotating shaft at intervals from each other, a plurality of fixed blades 60 through which the rotating shaft rotatably passes and which form a main cutter A together with the rotating blades, and a supporting frame 38 which has vertical plates 40 that hold the outer end portions of the fixed blades and whose upper end is fastened to the upper portion of the inside of the treatment tank.
摘要:
An outer cutter formed with hair introduction slits and attached to an electric shaver in a substantially inverted U-shape, in which recessed portions, in which the shaving surface side of the outer cutter is recessed, are provided adjacent to one or both end portions of the slits, so that the end portions of the slits are formed as hair introduction openings that introduce hair.
摘要:
An outer cutter of a reciprocating type electric shaver in which an inner cutter makes sliding contact with an inside surface of a curved portion of the outer cutter, the curved portion being formed by bending a thin metal plate, which has numerous hair entry apertures, into a curved shape; and the curved portion being provided at both ends thereof with blocking portions that cover both ends of a space defined by the curved portion so as to prevent cut hair from being discharged to outside of the outer cutter, the blocking portions being formed integral with the curved portion.
摘要:
An electric shaver having a cutter head that includes a movable cutter unit. With a single switching operation of a mode-switching dial that switches the operating mode of the shaver and is installed on the shaver main body, the movable cutter unit is moved upward or downward from a normal position, and the angle of inclination of the cutter head with respect to the shaver main body 1 is varied as well.
