is formed. In addition, the hair is introduced into the hair introduction hole 18 of the outer cutter 17 from this edge portion 23 toward the inner side.
A large number of groove-shaped hair guide portions 24 are formed in parallel.

Also, the outer blade mounting plate portion 2 at the bottom of this hair guide body 21
Locking pawls 26 whose upper and lower surfaces are inclined upward are formed on both sides of the inner surface of 5, and a plurality of outer cutter fixing protrusions 27 are protruded between both of the locking claws 26. An engaging pawl 28 is formed to protrude below the fixing protrusion 27 .

Next, the operation of this embodiment will be explained.

A pair of hair guides 21 are brought into contact with the inner surfaces of both ends of the outer cutter 17, the locking pawls 26 are inserted into the mounting holes 19, and the fixing protrusions 27 are inserted into the fixing holes 20 and fixed by welding. The hair guide body 21 is fixed.

Next, this outer cutter 17 is bent into a substantially U-shape, and placed in the outer cutter mounting portion 13 of the outer cutter case 12, and the locking claw 2
6 is inserted into the locking hole 15 and locked, and the engaging claw 2
8 into the engagement hole 16. And this outer blade 17
The outer cutter case 12 with attached is removably attached to the main body 10, and the inner cutter 11 attached to the main body 10 is attached.
When the inner cutter 11 is placed in the outer cutter case 12, the inner cutter 11 is pressed against the inner surface of the outer cutter 17 by the force of the spring, and is pulled by the outer cutter 17 in the direction of inclination of the locking claw 26. It is securely locked in the stop hole 15. At this time, the fixing protrusion 27 is located in the notch recess 14.

Next, during shaving, the hair guide body 21 is brought into contact with the outer surface of the hair guide body 21 and moved upward. At this time, the edge portion 23
The edge part 23 is curved in a concave arc shape so that it fits into the skin, and the entire edge of the edge part 23 is in contact with the skin, and the long hair or the hair that is in close contact with the skin is raised from the tip of the hair to form the seventh part.
As shown in the figure, the hair is introduced from the hair guide portion 24 into the hair introducing hole 18 of the outer cutter 17 and cut by the inner cutter 11 that slides back and forth along the inner surface of the outer cutter 17.

As shown in FIG. 8, the hair guide part 24 of the hair guide body 30 is formed from the inside that is spaced one level lower than the edge part 23 toward the outer blade 17, so that the long hair region is formed so that the hair is in close contact with the skin. On the other hand, even if the edge portion 23 contacts in an inclined manner, the hair can be reliably guided to the outer cutter 17 by the hair guide portion 24.

Next, another embodiment will be described with reference to FIGS. 9 and 10. In the embodiment described above, the upper end surface 22 of the hair guide body 21 is inclined downward from the edge portion 23 on the outer edge side toward the outer blade 17 side. Although the bristle guide part 24 is formed on this inclined surface, the upper end surface 32 of the bristle guide body 31 is inclined upward from the edge portion 23 on the outer edge side toward the outer cutter 17 side, and The hair guide portion 24 may be formed downward toward the blade 17 side.
