がある。 Conventionally, this type of reciprocating electric shaver is shown in Fig. 1, an external perspective view, Fig. 2, an enlarged sectional view taken along line A-A, and Fig. 3, a longitudinal sectional view a and a plane of the movable blade. As shown in Figure b, a boss 3 is attached to a plastic base 2 that is removably attached to the main body cover 1.
A spring 4 is fitted into this boss 3, and a movable blade 5 having comb-shaped cutting edges is fitted thereon so as to be slidable in the length direction, and furthermore, comb teeth are similarly fitted onto the boss 3. A fixed blade 6 having a shaped cutting edge is fixed to the boss 3 with a pin 7, and a movable blade 5 is reciprocated in the direction of arrow B in FIG. The fixed blade 6 and the cutting edge portion 8 of the movable blade 5 are configured to cut hair by driving. In such a conventional reciprocating electric shaver, as shown in FIG. Since the movable blade 5 is made of a thin metal plate, the pressure on the contact surface between the drive rod and the movable blade is high, and if used for a long period of time, the movable blade or the engagement part of the drive rod will wear out and the engagement will occur. The clearance at the joint increases and the noise increases. In order to prevent such abrasion of the engagement part, it is possible to insert a cushioning material such as plastic into the engagement part, but if such a cushioning material is inserted, the drive rod may be damaged even if it is not. The edge of the razor becomes thicker, which causes the movable blade and the fixed blade to overlap, making the razor thicker where it comes into contact with the skin, making it difficult to shave hair. be.

たものである。 The present invention aims to improve such drawbacks by extending the movable blade longer than the fixed blade in its sliding direction, and attaching a plastic engagement member to the end of the movable blade that does not overlap with the fixed blade. By insert-molding and integrally forming the drive rod into the hole provided in this engagement member, wear is prevented at the engagement part between the movable blade and the drive rod, and at the same time, the part of the razor that comes into contact with the skin is prevented. This allows the thickness to be reduced.

る。 FIG. 4 shows an embodiment of the present invention, in which a is a longitudinal sectional view of the blade portion and b is a plan view of the movable blade. The following description will be made with reference to FIGS. 1, 2, and 4. A base 2 made of plastic is detachably attached to a main body cover 1 of the electric shaver using an attachment/detachment button 10. A boss 3 is integrally formed on the base 2, and a movable blade 5 is fitted into the boss 3 with a spring 4 interposed between it and the base 2, and the movable blade 5 is slidable in the left-right direction in FIG. Further, a fixed blade 6 is fitted onto the fixed blade 6, and the fixed blade 6 is fixed to the boss 3 with a screw 7. The movable blade 5 extends longer than the fixed blade 6 in its sliding direction and is always slidably pressed against the fixed blade 6 by the spring 4, and also extends longer than the fixed blade 6 and is movable at an end that does not overlap with the fixed blade 6. An engaging member 11 made of plastic that is thicker than the blade 5 is integrally formed by insert molding. Reference numeral 9 denotes a drive rod that is reciprocated in the direction of arrow B by a motor and a cam mechanism (not shown), and its tip is removably fitted into a hole provided in the engagement member 11.
毛を剃る時には、固定刃６と可動刃５が重なつ
た刃先の部分を皮膚に平行に当て、固定刃６と可
動刃５とで毛を切断するのである。 When shaving hair, the overlapping portion of the fixed blade 6 and movable blade 5 is applied parallel to the skin, and the fixed blade 6 and movable blade 5 cut the hair.

なく、使い勝手の良い電気かみそりが得られる。 In the electric shaver of the present invention configured as described above, since the thick plastic engaging member 11 is formed integrally with the movable blade 5, wear at the engaging portion with the drive rod 9 can be prevented. In addition, since the engaging member 11 is provided at the end of the extension of the movable blade 5 that does not overlap the fixed blade 6, even if the engaging member is inserted, the thickness of that part will not become too thick. Furthermore, by lengthening the extension of the movable blade and separating the cutting edge where the cutting edges of the fixed blade and movable blade overlap from this engagement part, the thickness of the razor in contact with the skin can be made even thinner than before. be able to. By reducing the thickness of the razor in contact with the skin in this way, when shaving hair, you can clearly see the state of the blade edge and the shaving edge, making it easier to shave, and eliminating the possibility of shaving off unshaved hair or hair that should be left behind. You can get an electric razor that is easy to use and is easy to use.
