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: 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 a blade unit that achieves both smooth skin sliding in a wide area and ease of shaving in a narrow area. Blade unit according to the present disclosure comprises four or more outer blades extending in a first direction and sliding member extending in the first direction, and blade unit is attached to electric razor, wherein at least two outer blades included in the four or more outer blades are arranged on both sides of sliding member.

Abstract: A hair cutting device includes a grip, a head disposed external to one end of the grip, the head including a cutting unit that works on hair, and a joint connecting the grip and the head. The joint includes a base connected to one of the grip and the head, and a slide portion connected to the other of the grip and head and held to be slidable within a predetermined area on a slide plane that is a plane intersecting an alignment of the grip and the head. Accordingly, the hair cutting device including the head that has an excellent ability to lessen impact which is made when the head hits the skin and to follow the skin surface is provided.

Abstract: Slit blade block of an electric shaver of the present disclosure includes a slit outer blade having a plurality of outer blade pieces, a slit inner blade having a plurality of inner blade pieces, and comb provided outside the slit outer blade. Comb has a plurality of protruding portions protruding in a direction away from the slit outer blade. The plurality of protruding portions includes a plurality of types of protruding portions having different shapes. The present disclosure can provide a slit blade block having a comb that scoops lying long facial hair more easily, and an electric shaver provided with the slit blade block.

Abstract: Provided is a method of producing an outer blade for a hair cutting device from a material including bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The material is placed on a base. Next, a first tool having a leading end that has a gradually increasing width in a direction away from the material is used to press at least one part of each of the bars in a direction from a counter base-side first face of each of the bars toward a base-side second face of each of the bars. An edge of the first face of each of the bars is caused to project widthwise and to move toward the second face to be farther from an intermediate part of the first face.

Abstract: An outer blade for a hair cutting device, the outer blade being mounted to an end of a main body of the hair cutting device, includes bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The outer blade also includes, at a skin-surface-contact-side first face of each of the bars, an agent holding part configured to hold an agent that is a substance having a predetermined effect on a skin surface, the agent holding part being a surrounded recess heading from the skin-surface-contact-side first face of the bar toward an inner-blade-side second face of the bar. Thus, the agent such as foam or gel can be held by the agent holding part at the skin-surface-side face of the outer blade, and friction can be reduced between the outer blade and the skin surface by the agent held by the agent holding part.
