Therefore, when the clipper is advanced, the hair introduced into the hair escape comes into contact with the piercing surface and is pushed forward. Therefore, the hair before cutting is pushed forward by the pushed-down hair and cut in a state longer than the hair-cutting height, and the hair-cutting height may be uneven.

  Then, an object of this invention is to obtain the clipper which can make the hair cutting height more uniform.

  In the present invention, there is a fixed blade having a main body portion in which a plurality of comb protrusions having blades formed on both sides are arranged in parallel, and a main body portion in which a plurality of comb protrusions having blades formed on both sides are arranged in parallel. And a movable blade that is in sliding contact with the fixed blade, and a hair clipper that reciprocally slides the movable blade in a direction in which comb protrusions are juxtaposed with respect to the fixed blade to cut hair. The plurality of comb projections of the fixed blade have a skin contact surface that comes into contact with the skin and a sliding contact surface with which the comb projection of the movable blade comes into sliding contact. The main body portion has an opposing surface that opposes a plane including the skin contact surface, and the shortest distance between the flat surface including the skin contact surface and the opposing surface of the main body portion of the fixed blade, and the surface of the clipper main body. Including the skin contact surface on the entire surface on the side facing the plane including the skin contact surface Distance from the plane, and major, wherein at a plane including the skin-contact surface or the distance between the tip of the comb projection of the movable blade.

  According to the present invention, in the clipper that cuts the hair by reciprocatingly sliding the movable blade with respect to the fixed blade in the juxtaposed direction of the comb protrusion, the flat surface including the skin contact surface and the opposed surface of the main body portion of the fixed blade. The distance between the shortest distance and the plane including the skin contact surface in the entire surface of the surface of the hair clipper main body opposite to the plane including the skin contact surface is the distance between the plane including the skin contact surface and the comb projection of the movable blade. It is set to be more than the distance from the tip. As a result, with the skin contact surface in contact with the head, the hair that has been trimmed by the blade provided on the comb projection of the movable blade on the opposite surface and the surface that faces the plane including the skin contact surface of the clipper body It can be present at a position higher than the cutting height. Therefore, it can suppress that the hair which was clipped contact | abuts to the surface on the side which opposes the flat surface containing the opposing surface and the skin contact surface of a hair clipper main body. That is, since it is suppressed that the cut hair is pushed forward, it is possible to prevent the hair before cutting from being pushed forward, and the hair cutting height is made more uniform. Can do.
