い。2. Description of the Related Art A hair cutter blade composed of a comb-shaped fixed blade and a movable blade requires a spring member for pressing the movable blade against the fixed blade, and is generally called a push-up spring. A spring member is used separately. As one type of hair cutter, there is an electric hair clipper used for shaving during surgery. In this case, since the blade must be disposable, the necessity of a separate spring member poses many problems in terms of cost including assemblability.

Influence is large and it is practically difficult to obtain good adhesion accuracy. The present invention has been made in view of such a point, and an object of the present invention is to provide a hair cutter that can secure good sharpness in addition to cost reduction and improvement in assemblability by reducing the number of parts. To provide a blade.

る。A spring member for bringing the movable blade 22 into close contact with the fixed blade 21 is integrally formed on both sides of a driver fitting hole 22b formed by burring at the center of the movable blade 22. It is formed as a spring piece 27,27. These spring pieces 27 formed by cutting and raising from the movable blade 22 are formed such that an action point 27a that comes into contact with the back surface of the blade base 20 is on the blade tip side of the movable blade 22 and a fulcrum 27b is on the opposite side. And the fulcrum 27b and the action point 2
7a is formed to have a C-shape so as to increase the distance between the two. The blade side of the movable blade 22 is fixed to the fixed blade 21.
The fulcrum 27b and the action point 27a are set so that the force pressing against the cutting edge becomes larger, and by increasing the distance between the fulcrum 27b and the action point 27a,
This makes it easy to set the pressing force. Here, a slide guide groove 22a that engages with the boss 24 of the blade base 20 and a contact portion of the driver fitting hole 22b with the driver 7 are located between the fulcrum 27b and the application point 27a. For this reason, also in this respect, an appropriate spring force can be obtained, and the movable blade 22 can be prevented from being twisted at the time of driving, and a stable sharpness can be obtained.

Ru der those obtained the improvement of the assembling property. In addition, the spring piece has one end point of action on the edge of the movable blade and the other end has a fulcrum.
Is formed in a C-shape having the opposite side , the spring piece exerts a spring force so as to press the cutting edge side of the movable blade more strongly against the fixed blade side than the opposite side due to the positional relationship between the action point and the fulcrum. what Monodea, Therefore high edge side of the contact precision between the movable blade and the fixed blade in state, and are not for good sharpness, also spring piece which is formed in a C-shaped supporting point and create
The distance between the point of use is longer and a stable spring constant is obtained.
That can easily set the pressing force of the cutting edge
It is. A slide that guides the reciprocating movement of the movable blade
The ride guide groove is located between the point of action and the fulcrum.
Because it is provided inside the C-shape,
The dimension between the guide groove and the point of action of the spring piece is reduced
To prevent the movable blade from twisting during driving
Inside the C-shaped spring piece.
The guide blade can be accommodated and the movable blade can be downsized.
It is easy to do it.
