Are engaged with the annular groove 16 to hold the movable cylinder 2 at the height position shown in FIG.

An elastic member 17 made of an O-ring or the like separately provided
2 and 3, the movable cylinder 2 is pulled up to a maximum height position as shown in FIGS. 2 and 3, and the projection 8 of the tightening cylinder 7 is engaged with the annular groove 16 of the movable cylinder 2. When it is engaged with the nut, it is arranged so as to be sandwiched between the upper end of the nut 15 and the lower end of the ridge portion 8 and deformed in the thickness direction to elastically press the peripheral surface of the movable cylinder 2. ing.

Therefore, if the arm or elbow collides with the holder 14 while washing the hair while the holder 14 is held at the height shown in FIG. 2, the movable cylinder 2 and the tightening cylinder 7 Since there is frictional resistance due to the elastic member 17, the holder 14 and the movable cylinder 2 do not rotate vigorously but stop with a slight rotation.

FIG. 4 shows a second embodiment of the present invention. The tightening cylinder 7a of this embodiment has an annular inner groove 18 formed below the ridge 8a. Accordingly, when the movable ridge 2 is pulled up to the maximum height position and the ridge 8a is engaged with the annular groove 16, the tightening portion 9 is contracted by the tension spring 11, and the elastic member 17 is formed between the annular inner groove 18 and the movable cylinder 2. Since it is pressed in the radial direction between the peripheral surfaces, frictional resistance is generated when rotating between the movable cylinder 2 and the tightening cylinder 7, and the holder 14 and the movable cylinder 2 do not inadvertently rotate vigorously.

FIGS. 5 and 6 show a third embodiment of the present invention. In this embodiment, a resistance member D is disposed above a nut 15 in place of the above-mentioned elastic material. The resistance member D has a cylindrical ring 19 in which concavo-convex portions 20 are continuously formed at regular intervals on the entire circumference of the upper peripheral surface, a spring 21 for constantly urging the ring 19 upward from the nut 15, and a tightening member. A groove 22 is formed continuously on the lower part circumference of the protruding portion 8 of the cylindrical body 7b so as to face the uneven portion 20.

In this embodiment, when the movable cylinder 2 shown in FIG.
0 and the groove 22 of the ridge portion 8 are engaged with each other, so that the movable cylinder 2 does not rotate with a small external force. Since the concavo-convex portion 20 of the ring 19 urged upward by 21 rotates while sequentially climbing over the groove 22 of the ridge 8, the rotation of the movable cylinder 2 can be slowed down.

Conversely, the resistance member D may have a groove formed on the upper peripheral surface of the ring and an uneven portion formed on the lower circumference of the ridge.
