As a result, the amount of the hair 9 cut by the blade portion 2 can be reduced, a large amount of hair 9 can be prevented from being cut at a time, and the hair 9 can be cut little by little. In addition, no matter how many times the hair is cut, it does not fall below a certain finished thickness, so that it is possible to cut without worry and without fail, and that anyone can easily cut the entire hair 9 evenly, resulting in a good finish. . Further, the cut shavings are sucked through the suction port 8, so that the shavings can be easily treated and the cleaning can be easily performed.

Since the suction member 7 is attached to the lower side of the cylindrical hair cutter body 10, the shavings cut by the blade portion 2 fall to the lower side of the blade portion 2, and the suction member 7 Is sucked from the suction port 8 of the hair, and the suction property of the shavings is improved. In addition, the hair cutter body 10 can be easily grasped by hand, and a switch disposed on the upper surface of the hair cutter body 10 can be easily operated, so that operability is also improved.

A hair holding portion 6a located above the blade portion 2 is attached to the distal end of the support member 4, and a hair holding portion 6b located below the blade portion 2 is attached to the suction member 7.
The hair holding portions 6a and 6b can be supported using the support member 4 and the suction member 7, respectively, and the structure can be simplified. In addition, the hair holding portion 6b attached to the suction port 8 side has an interval E1 from the blade surface 5 of the blade portion 2.
Since it is slidable in the front-rear direction toward the direction where E3 changes, the intervals E1 to E3 between the blade portion 2 and the hair pressing portion 6b can be arbitrarily set and changed. For example, as shown in FIG. 5, the lower hair holding portion 6b is arranged at the position indicated by the N line, as shown in FIG. 6, retracted backward B from the N line, or as shown in FIG. By moving the hair forward forward F, the distance E between the contact surface (Y line) of the scalp 3 and the upper hair holding portion 6a, and the contact surface (Y line) of the scalp 3 and the lower hair Intervals E1 to E3 with holding part 6b
Can be made different from each other, so that even if there is a difference in suction power between suction devices (for example, a vacuum cleaner),
By adjusting the intervals E1 to E3, the thickness of the hair 9 from the scalp 3 can be made to a thickness suitable for the user's preference, and it is possible to prevent excessive cutting or difficulty in cutting, and It is easy to adjust the finishing speed.

FIG. 8 shows another embodiment, in which a hair holding portion 6b attached to the suction port 8 side of the suction member 7 is constituted by a rotatable roller 11. Here, the surface 11a of the roller 11 is made of a member having a small frictional resistance. Other configurations are the same as those in FIG. When the shavings cut by the blade portion 2 are sucked from the suction port 8 located below the blade portion 2, the shavings are guided to the suction port 8 by the rotation of the roller 11, whereby Hair shavings are less likely to be clogged in the gap between the blade portion 2 and the hair holding portion 6b. And roller 1
1 is made of a member having a small frictional resistance so that the shavings cut by the blade portion 2 are temporarily
