  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, in order to make a difference between the radial thickness t1 of the portion 10K provided with the first protrusion 12 and the radial thickness t2 of the other portion 10N, the outer circumference of the rotating ring 10 is changed. The shape along the inner periphery is a circular shape, and the shape along the inner periphery is an elliptical shape in which the acting direction of the load R (vertical direction in the figure) is a short axis. As shown in the modification of FIG. The shape along the inner periphery of the rotating ring 10 may be circular, and the shape along the outer periphery may be elliptical.

  Further, in the above embodiment, the first convex portion 12 is restricted by the lid-shaped convex portion 22a only when the grip portion 5 is extended with respect to the main body portion 3 and put into use. As in the modifications shown in FIGS. 17 and 17, the click convex portion 22b of the above embodiment is also provided with a lid-shaped convex portion 22a, and the lid-shaped convex portion 22a has both the use position and the folded position. The first convex portion 12 may be sandwiched and supported. In such a configuration, it is possible to suppress the grip of the grip portion 5 at the folding position in addition to the use position.

  Moreover, in the said embodiment, although the rotation ring 10 was formed in cyclic | annular form, you may make it other shapes, such as semicircle shape, for example.

  In the above embodiment, the rotary ring 10 is provided integrally with the main body 3 in the rotational direction, and the click ring 20 is provided integrally with the grip portion 5 in the rotational direction. 10 may be provided on the grip portion 5 side, and the click ring 20 may be provided on the body portion 3 side.

  Furthermore, although the hair care device has been described as the hair dryer 1 in the above embodiment, the present invention can be applied to any hair care device in which a foldable grip portion is connected to a body portion having a hair care function. it can.
