摘要： In a reciprocation type electric shaver having an outside blade unit detachable from a main body, the outside blade unit comprises a main blade, a slit blade and an outside blade holder for holding the main blade and the slit blade capable of floating up and down. A coupling structure for coupling the slit blade on the outside blade holder has a retaining structure for engaging the slit blade and the outside blade holder in a lateral direction of the outside blade unit so as to prevent disengagement of the slit blade from the outside blade holder when the slit blade is floated up and down with inclination. The retaining structure is a pair of fitting recesses formed on the slit blade and a pair of fitting protrusions formed on the outside blade holder.

摘要： An electric shaver including a hand grip 10 configured to be gripped by a user' s hand, and a blade head 20 provided on an upper end of the hand grip. The blade head carries at least one shaving unit 50 comprising an outer blade foil 70 and an inner blade 80 driven in a shearing engagement manner with the outer blade foil. The outer blade foil has a plurality of holes in which hairs are introduced. The outer blade foil is elongated and has a length, and is curved along a width direction to form a generally C-shaped cross section, and is curved convexly and uniformly along its length to have a longitudinal curved outline. A radius of to curvature of the longitudinal curved outline is 150 mm to 350 mm.

摘要： A shaving head for a dry shaver is capable of increasing the cutting efficiency, yet allowing the use of the inner cutter of simple structure. The shaving head has a slit cutter unit composed of an outer cutter shaped to have a top surface for contact with a user's skin, and an inner cutter in contact with a bottom surface of the outer cutter. The outer cutter has a U-shaped structure with a pair of legs connected by a crossbar, and to have a plurality of slits which are spaced in a lengthwise axis of the outer cutter to leave a plurality of bridges each between the adjacent ones of the slits. The slits extend continuously over a full width of the crossbar and into upper ends of the legs in a direction generally perpendicular to the lengthwise axis, giving two straight slit paths respectively on opposite width ends of the outer cutter. The straight slit paths on the opposite width ends are staggered with respect to each other along the lengthwise axis. Each of the bridges extends along the width axis of the outer cutter to make the bottom surface of the outer cutter smoothly continuous over the full length of the bridge, and that each bridge is formed at its longitudinal center with a deflection which is angled with respect to the width axis so as to leave, between the adjacent ones of the deflections, an angled path through which the straight slit paths of each slit extends continuously.

摘要： An electric shaver includes: a main body; an outer blade provided to an end of the main body and having a blade hole defined by a bar; and an inner blade provided inward of the outer blade and configured to reciprocate in a longitudinal direction of the outer blade to cut hair in the blade hole with the outer blade. The bar has a hair raising portion coming in contact with hair upon movement of the outer blade on a skin surface to raise hair up from the skin surface. A contact pressure on the skin surface to be exerted by the outer blade in a first portion of the outer blade is greater than that in a second portion of the outer blade. Hair raising performance in raising hair up from the skin surface in the first portion is smaller than hair raising performance in the second portion.
