The nose hair cutter as described above is inserted into the nostril 7 and the motor 9 is rotationally driven to rotate the inner blade 2, whereby the side surface portion, the upper surface portion, and the side surface of the slit outer blade 1 are rotated. The nose hair 61 introduced from the slit portion of the curved surface connecting the upper surface and the upper surface is cut. In this case, as shown in FIG. 9, the nose hair 61 introduced from the side surface portion of the slit outer blade 1, the upper surface portion, and the slit portion of the curved surface portion connecting the side surface and the upper surface can be reliably cut, and the conventional example shown in FIG. Has a problem in that the nose hair 61 at the center of the nostril 7 and the nose hair 61 at the nasal bridge 60 portion at the entrance of the nose hole 7 cannot be reliably cut, whereas the one of the present invention is Central nose hair 61,
The nose hair 61 in the nose bridge 60 portion at the entrance of the nose hole 7 can be surely cut.

By the way, in the present invention, if the hole diameter a of the nose hole 7 shown in FIG. 6 (a) is about 10 to 13 mm, the slit outer blade 1 can be easily used in the nose hole 7, Bridge 6
The diameter b of the tip of the slit outer blade 1 shown in FIG. 6 (b) is optimally about 7 to 8 mm in order to smoothly shorten the 0 portion, and the curvature radius of the curved surface portion of the slit outer blade 1 is the minimum. However, about 1.5 mm is necessary to eliminate irritation on the skin. In addition, from the introduction of the nose hair 61, the slit outer blade 2
It is better to widen the inner diameter c of the central opening of the device to the maximum. From this fact, c is 3 to 4 mm, which is the best in use and function.

11 to 13 show another embodiment of the present invention. In this embodiment, the inner blade 2 is composed of two kinds of inner blades for upper surface 2a and inner blades for side surface 2b.
The inner blades 2 of the kind are attached to the inner blade frame 6 so as to be alternately located in the rotational direction as shown in FIG. The inner blade 2a for the upper surface is provided with cutting edge portions for the upper surface and the curved surface.
2, the elastic force of the spring 3 causes the upper inner blade 2a to move upward.
Is elastically urged upward and is in contact with the upper surface portion and the curved surface portion of the slit outer blade 1 by an appropriate elastic force. Further, the side inner blade 2c is provided with a side cutting edge portion, and the side inner blade 2c is elastically urged laterally by the elastic force of the spring 3 as shown in FIG. It is in contact with the side surface by an appropriate elastic force. In this way, by separately providing the inner blade 2a for the upper surface and the inner blade 2b for the side surface, both the upper surface cutting blade and the lower surface cutting blade cut a large amount of nose hairs 61 at a time, and the load becomes large, so that the inner blade 2 Can be prevented from being lifted from the inner surface of the slit outer blade 1 and pulled without being cut, the motor being locked due to overload, and the battery being exhausted quickly.

FIG. 14 shows still another embodiment of the present invention. In this embodiment, the spring 3 is of two types, a spring 3a for upward pressing and a spring 3b for lateral pressing. That is, as shown in FIG. 14, a spring force for laterally pressing the inner blade 2 applies a lateral spring force to the side surface of the inner blade 2 to elastically contact the side surface of the slit outer blade 1. There is. On the other hand, an upward pressing spring 3a such as a coil spring is interposed between the bottom portion of the fitting tubular portion 16 of the inner blade frame 6 and the joint 11 to press the upward pressing spring 3a.
The upper surface of the inner blade 2 is elastically brought into contact with the upper surface of the slit outer blade 1 by a. In this way, by separately providing the spring 3a for upward pressing and the spring 3b for lateral pressing, the pressing principle for sharpness can be simplified and the sharpness can be improved.

FIG. 15 shows still another embodiment of the present invention. In this embodiment, the upper bottom of the portion 30 for arranging the concave wire spring provided on the inner blade 2 is the inclined portion 40, and the inclined portion 40 is contacted with the horizontal wire rod portion 25d of the spring 3 to cause the spring. The inner blade 2 is elastically biased obliquely upward by pushing the inclined portion 40 by the elastic force of 3, and the upper surface, the curved surface portion, and the side surface portion of the inner blade 2 are elastically biased upward. The slit outer blade 1 is elastically contacted with the upper surface portion, the curved surface portion, and the side surface portion, respectively. Here, as shown in FIG. 16, the vertical hole portion 25 of the inner rib 23 is a vertically long hole that is inclined obliquely, and the internal hole 2 is formed in the obliquely inclined vertical hole portion 25.
It is also possible to slidably insert the slidable slide piece 42 so that the slidable piece 42 can be slidably slid while being guided by the slantly slanted vertical hole portion 25. With this configuration, when the inner blade 2 is elastically biased by the spring 3 in an oblique direction and is slid, the inner blade 2 slides while being smoothly guided.
