断させようとしたものが提案されている。 This type of electric shaver, for example, a reciprocating electric shaver, as shown in FIG.
Projections 62, 62 having an arch-shaped cross section extending linearly from one end to the other end are bulgingly formed on the surface of the outer cutter 63, and each of the above-mentioned projections 62 has a
It has been proposed that a large number of slits 64 are arranged in parallel across the length of the hair to shear the long hair, which tends to lie down, without missing as much as possible.

ている皮膚Ｍが傷つけられるおそれがある。 However, in the above configuration, the force of the protruding ridges against the pressing force of the skin is divided in the longitudinal direction by the plurality of slits 64, and as shown in FIG. When the part 63a is pressed against the skin M and moved in the direction of the black arrow, the parts between the slits 64 of the protrusion 62 are unlikely to deform in the same direction at the same time, and as shown in FIG. It tends to deform in one direction. For this reason, not only does the raising effect at each longitudinal portion of the protrusion 62 tend to be canceled out, but also the slit 64
There is a risk that the skin M pressed against the protrusions 62 may be damaged by various deformation movements between the two.

も多く、剪断効率が悪い。 Furthermore, the hair H captured by the slit 64 is not cut until it reaches the non-projecting part 63a of the inner blade 61 which is in contact with the protruding part 62. In other words, even if the hair H is caught in the slit 64 of the protrusion 62, there is no guarantee that it will be cut reliably, and it often protrudes from the slit 64 again, resulting in poor shearing efficiency.

点を解消したものである。 Therefore, this invention has a protrusion extending along the axial direction of the inner cutter, and near the inner side of the protrusion, a large number of slits are provided along the protrusion along the protrusion. By arranging them side by side, the above drawbacks are solved.

以下、この考案の一実施例を図面にしたがつて

An outer blade 13 is stretched. Reference numeral 14 denotes a motor housed within the main body case 11, and an eccentric shaft 16 is fixed to a rotating shaft 15 of the motor 14. Reference numeral 17 denotes a vibrator that is driven by the eccentric shaft 16 via a lever 18. A drive rod 17a is protruded from the upper surface of the vibrator 17.
An inner blade holder 19 is connected to the tip of a. 2
Reference numeral 0 designates an inner cutter body formed by supporting a large number of inner cutter blades 21 in a skewered manner with a pipe 22 or the like. The outer blade 13 receives the spring force of
It is pressed against the inner surface of the motor 14, and is reciprocated in the directions of arrows a and b by receiving the rotational force of the motor 14 via the vibrator 17.

外刃取付用の係止片である。 As shown in FIG. 2, the outer cutter 13 is formed into a rectangular shape from a metal plate by known pressing means, etching means, electroforming means, etc., and is flexible. As shown in an enlarged view in FIG. 3, the outer cutter 13 has a direction perpendicular to the axial direction of the inner cutter body 20, in other words, a reciprocating direction (directions of arrows a and b) and a direction perpendicular to the direction of the reciprocating motion (direction of arrow c). Protrusions 24, 24 having an arch-shaped cross section and extending along the reciprocating direction are formed at least in part (both sides in this embodiment), and these protrusions 24, 24 extend through the hair introduction holes. In addition, at a position near the inner side of each protrusion 24,
A large number of slits 25 are arranged in parallel along the respective protrusions 24, oriented in a direction that intersects with each of the protrusions 24, for example, in a perpendicular direction. 26 is a large number of small holes formed in almost the entire area of the outer cutter 13 except for the protrusion 24 and the slit 25, 27 is a reinforcing plate for the outer cutter 13, and 28 is a locking piece for attaching the outer cutter.

的である。 In the above configuration, if the top of the protrusion 24 and the non-protrusion portion 13a of the outer cutter 13 are moved in the direction of the black arrow while pressing against the skin M as shown in FIG. Skin M between site 13a
Since the long hair H is stretched, the long hair H in between is raised, and the raised long hair H is captured by the slit 25 and sheared as is in accordance with the above-mentioned moving operation. In this case, since the slits 25 are located near the inner side of the protrusions 24, the long hairs H are sheared without interruption when raised, and the hair is effectively captured.

る。 In particular, since the slits 25 do not cross the protrusions 24 that do not have hair introduction holes, the force of the protrusions 24 against the skin M acts without being divided in the long hair direction, thus making the skin M taut. The raising action is no longer canceled out as in the conventional case, and the raising can be performed satisfactorily over the entire length of the protrusion 24. Further, the deformation of the protrusion 24 during the movement operation also occurs integrally in the same direction over the entire length as shown by the chain line in FIG.
It is also possible to eliminate the fear that the skin M will be damaged by.

りを提供することができる。 As described above, this invention involves arranging a number of slits in parallel along the protrusion in the vicinity of the protrusion that does not have hair introduction holes formed on the outer blade and facing in the direction perpendicular to the axial direction of the inner blade. As a result, it is possible to provide an electric shaver that has a good hair-raising effect on long hair and can improve trapping efficiency without causing damage to the skin.
