Abstract: This slit blade block includes multiple comb teeth adjacent to multiple outer blade pieces. Each comb tooth has a leading end surface, and a protruding part protruding in a direction away from the outer blade pieces. The protruding parts include an apical part that is the outermost end in said direction away from the outer blade pieces. The leading end surfaces of the protruding parts are positioned between the leading end surfaces and the base end surfaces of the adjacent outer blade pieces. Length L1 in the height direction, defined by the apical part of the protruding parts and the leading end surfaces of the protruding parts, is less than or equal to thickness L2 of the outer blade pieces, defined by the leading end surface and the base end surface of the outer blade pieces.

Abstract: An electromotive unit includes a linear motor, a motor case containing the linear motor, a movable element connected with the linear motor and reciprocatingly driven with respect to the motor case, and a sealing material sealing the gap between the movable element and the opening of the motor case. The sealing material includes a contact portion contacting the movable element; and a recessed portion formed around contact portion, having a ring-shaped groove facing the outside of the motor case, and elastically deformable according to reciprocating movement of the movable element. This aspect provides an electromotive unit that hardly generates noise while the movable element is being reciprocatingly driven; and a small-size electrical appliance including the electromotive unit.

Abstract: A comb-shaped outer blade that scoops up body hair while suppressing the damage to the skin. The comb-shaped outer blade includes a base part that has a rod shape and extends in a first direction, a comb-blade attachment part that has a plate shape and extends in the first direction and a second direction, open blade parts each of which has a cantilever shape and protrudes from base part in a third direction, and bent blade parts arranged alternately with the open blade parts in the first direction, the bent blade parts connecting the base part to the attachment part. Each of the bent blade parts includes a protruding part that protrudes from the base part along the third direction, bent part that is connected to a distal end of the protruding part, and connecting part that connects bent part and comb-blade attachment part in an inclined state.

Abstract: The present disclosure provides an electric razor in which a support frame that supports an outer blade and an inner blade, which constitute a block, can be smoothly removed. An electric razor according to the present disclosure includes a main body gripped by a user and a head having a blade block including an outer blade (that is, a slit blade, a mesh blade) and an inner blade disposed inside the outer blade and sliding with respect to the outer blade. The head includes a base, a support frame that supports the blade block so as to be able to float and sink, a case held by the support frame, a hook that locks the support frame or the case to the base, and at least one push-up member that urges the support frame in a direction away from the base.

Abstract: An electric razor reduces damage to the skin during shaving. The electric razor includes a head portion that holds a comb-shaped outer blade and mesh-shaped outer blades each of which extends in a first direction so as to be movable in a second direction intersecting the first direction, comb blade urging members that urge the comb-shaped outer blade in the second direction, mesh blade urging members that urge the mesh-shaped outer blades in the second direction, and an engaging mechanism that, when the mesh-shaped outer blades are moved toward a unit base against urging force of the mesh blade urging members, moves the comb-shaped outer blade in a state where the comb-shaped outer blade does not protrude from the mesh-shaped outer blades with respect to the unit base.

Abstract: The present disclosure provides an electric razor that can further suppress irritation to a skin. An electric razor of the present disclosure includes a body configured to be gripped by a user, a head having three or more blade blocks, and a head support connecting the head and the body to each other. The head support supports the head in a floatable-and-sinkable way with respect to the body. The head includes a case that supports the three or more blade blocks, and a blade float that allows each of the three or more blade blocks to float and sink with respect to the case. A first urging force with which the head support urges the head in a floating direction is larger than a second urging force with which the blade float urges the plurality of blade blocks which are one or more less than three or more blade blocks in a floating direction. The first urging force is smaller than a third urging force with which the blade float urges all of the three or more blade blocks in the floating direction.
