This locking portion 12a is integral with the dial 10 due to the force of the coil spring 11 of the lock dial 9, and moves outward to catch the hook 7e. The lock dial 9 is integrated with the dial 10 to move inward to prevent rotation of the dial 10 and to prevent rotation of the dial 10. The close state of the caught part 9a is canceled | released by making it approach the most), and the dial 10 is rotatable.

Next, adjustment of the hair clipper height in this Example is demonstrated. When the dial 10 is pushed in the direction in which the force applied by the coil spring 11 increases, that is, the inner side of the main housing 1, the lock dial 9 moves together with the dial 10 to catch the caught portion 9a. And since the locking state of the locking portion 12a is released, the rotation of the dial 10 becomes possible. As the dial 10 is rotated while pushing the dial 10 inwardly of the body housing 1, the attachment 5 becomes rotatable by being integrated with the dial 10 and the lock dial 9. In accordance with the rotation of the main body 1 can be moved in the front and rear direction. That is, the dial 10 becomes able to operate the attachment 5 when it is in a rotatable position.

And when the dial 10 rotates to the place where the display part 10a shows the predetermined | prescribed hair cutting height, the attachment 5 moves back and forth with respect to the main body housing 1, and the hair cutting height is set. When the finger is released from the dial 10, the dial 10 and the lock dial 9 are returned to their usual positions by the force of the coil spring 11, so that the hooked portion 9a is caught by the locking portion 12a. Therefore, the rotation of the dial 10 becomes impossible and the attachment 5 cannot move at the same time.

Therefore, the present embodiment enables the dial 10 to be moved to an operable position that enables the operation of the attachment 5 and an inoperable position that disables the operation, so that the dial 10 operates the attachment 5. When moving to the disabled position, it is possible to prevent the attachment 5 from operating unintentionally due to an incorrect operation of the dial 10 or an external force applied to the attachment 5, and as a result, the height of the hair clipper by the attachment 5 After setting, the height of the hair clipper can be prevented from being changed accidentally and the user can use it with confidence.

In the present embodiment, the sharpening height adjusting means is used as the attachment 5. In addition to this, for example, the fixed blade 3b is formed thinner as the thickness of the blade tip is directed to the tip, and the fixed blade 3b and the movable blade 3c are formed. ), The fixed blade 3b or the movable blade 3c may be configured to be movable in a direction orthogonal to the reciprocating direction of the movable blade 3c in the state of overlapping. This sharpener height adjustment means is a structure well-known by Unexamined-Japanese-Patent No. 4-117986.

In addition, in this embodiment, the guide part 1b is formed in the other surface of the main body housing, the guide part 5b is formed in the inner surface of the attachment 5, and the guide part 5b guides in the guide part 1b. Although configured as such, the place where the guide portion 1b and the guided portion 5b are provided is not limited to the above-mentioned place.
