であって、ばね板を略へ字状に折曲して形成しである。The present invention is based on a fixed blade (8@) having a comb-like cutting edge with small teeth (4) lined up in the left-right direction, and a movable blade that slides in contact with the fixed blade (8a) and reciprocates in the left-right direction. A pressing spring which arranges a blade (8b) to form a razor blade (3) and presses this movable blade (8b) from above to press it against a fixed blade (8m).
Of these, the suppressing contact portion to the movable blade (8b) is formed to be long in the left-right direction, and the width (6) of the suppressing contact portion in the left-right direction is the width of the suppressed portion of the movable blade (8b) in the left-right direction. This relates to an electric shaver characterized in that the width is the same as or larger than the combined width of the reciprocating motion of the movable blade (8b). In the following, the invention will be explained in more detail with reference to the illustrated embodiments. The housing il+ is made of synthetic resin, and is formed by connecting a connecting housing frame to the upper end of a vertically elongated cylindrical case main body guard, as shown in FIG. The connecting housing is formed in such a shape that a long head portion (ft) extends from the upper end of a neck portion (11) connected to the case body in the left and right directions. A razor blade i11 consisting of a fixed blade (8sc) and a movable blade (8b) is held in this head part.The cutting edge of the fixed blade (8m) is flr
It is formed in a comb-like shape along the left and right direction on the J edge. The movable blade (8b) reciprocates in the left-right direction with the fixed blade (8a), so that the comb-shaped cutting edge of the movable blade (8b) moves with the fixed blade (8a).
The blade is designed to slide reciprocatingly against the 8 m) cutting edge. −
is a pressing spring that presses the movable blade (8b) against the fixed blade (8m), and is formed by bending a spring plate into a substantially V-shape.

さくすることができる。The movable blade (8b) has a fixing hole at a position corresponding to the fixed column.
A large movable hole 1 (to) is formed in the left and right middle of the blade, and the movable blade (8b) can be moved in the left and right direction. Also, a through hole is formed in the pressing spring diagram at a position corresponding to the fixing column, and the pressing spring is inserted into the fixing column. The elasticity of this pressing spring brings the movable blade (8b) into pressure contact with the fixed blade (8a). A connecting seat is fixed to the center of the movable blade (8b). The connecting seat is open at the bottom, and the spherical part set of the drive rod set is housed therein as described above. For this reason, a tapered introduction part extending downward to the left and right is formed at the lower end of the connecting seat so that the spherical portion III can be easily accommodated within the connecting seat. In addition, fixed blade (8m
) is formed in the center of the movable blade (8b) with a laterally long through hole (57) through which a connecting seat fixed to the movable blade (8b) is inserted, and the connecting seat moves left and right within the through hole φη. Fixed blade (8m)
A comb-like cutting edge in which a large number of rectangular small teeth (4) are lined up in the left-right direction protrudes from the front edge of the blade. Fixed 'FJ (8m
) are formed on the front edge and the machine edge, respectively, over the entire length in the left and right direction, and the cutting edge is a central piece 6 with a fixed blade (8 m).
A rear piece is formed at the rear of the fixed blade (81) and is located above the center piece and parallel to the center piece. On the other hand, the movable blade (8b) has a serrated cutting edge protruding from the front rut where a large number of substantially triangular small teeth are arranged in the left-right direction. RI2 is formed on the front edge and the machine edge of the movable blade (8b), respectively, over the entire length in the left and right direction, and the cutting edge is located below the center piece 4 of the movable blade (8b). ) also extends a rear piece located below one side of the center and parallel to the center piece. In addition, a plurality of hair removal holes are formed in each center piece of the fixed piece (8 maple) and the movable piece (8b), and a plurality of similar hair removal holes (@) are formed in the pressing spring. The fixed blade (8a) and the movable blade (8b) are arranged 1 with their cutting edges and rear cutters aligned, and at this time, as shown in FIG.
A gap β force is formed between the central pieces of a) and the movable blade (8b). 1 during this time! Fixed blade (8
The contact area between a) and the movable blade (8b) becomes smaller, and when the movable blade (8b) reciprocates along the left-right direction, it acts between the fixed blade (8a) and the movable blade (8b). Frictional force can be reduced.

The central portion is curved in a shape that bulges in 40 directions, and the three portions are lined up approximately on the same straight line within the area perpendicular to the cutting edge of the razor blade (3). At this time, when the cutting edge of the razor blade (3) is made horizontal, the tip of the comb (6) protrudes furthest forward. Also, the adjacent comb fill t5i of the comb (6)
The distance between them is larger than the distance between the interlocking small teeth (4) of the fixed blade (8a).

るという利点がある。As described above, in the present invention, among the pressing springs that press the movable blade from above and press it against the fixed blade, the pressing contact portion to the movable blade is formed to be long in the left-right direction, and the middle of the left and right of this pressing contact portion is connected to the movable blade. The width is the same as or larger than the width of the suppressed part in the left and right direction and the reciprocating width of the movable blade, so
Even if the movable blade is at the maximum reciprocating width position (the position where it can swing the most from the center in the left-right direction), the left and right ends of the pressing contact part of the pressing spring can directly press the suppressed part of the movable blade. Therefore, even if the cutting resistance of the hair on both the left and right ends of the movable blade increases and the movable blade tries to bend due to the force, the pressure spring can prevent this, and the advantage is that stable cutting can always be obtained. .
