That is, by rotating the handle 16a, the bag nut 1
6 is tightened, the split ring 18 loaded in the cap nut 16 is also tightened, and the inner circumferential surface of the split ring 18 comes into pressure contact with the outer circumferential surface of the slide tube 5, clamping the slide tube 5, and the support body 3 is held at an arbitrary height. It is held at a certain point.

Further, when the cap nut 16 is loosened, the split ring 18 is also loosened, and the inner peripheral surface of the split ring 18 does not come into pressure contact with the outer peripheral surface of the slide tube 5, so that the slide tube 5 becomes freely slidable.

However, in the configuration described above, the bag nut 16
Since the slide tube 5 is held by rotating the split ring 18 and tightening the outer periphery of the slide tube 5, it is troublesome to operate each time, and when tightening the cap nut 16, the retainer is used. 7 rotates together, and the fixing nut 14 fixing the holder 7 to the counter B becomes loose, making the fixing of the holder 7 to the counter B unstable, which poses a problem in usability. .

(Technical Problem to be Solved by the Invention) A technical problem to be solved by the invention is to make the means for engaging the slide tube and the holder easy to operate and convenient to use.

(Technical means for achieving the technical problem) The technical means of the present invention for achieving the above-mentioned technical problem is to fix a slide pipe to the lower end of a support that supports the water discharging body so that it can be freely inserted and removed. The slide tube is inserted into a holder that is attached to the counter so as to be able to slide up and down, and a groove is provided on the outer circumferential surface of the slide tube, and a ball body that falls into the groove and engages, and the ball body is inserted into the outer circumference of the slide tube. The holder is provided with an engaging body consisting of an elastic body that urges the slide tube toward the surface, and a buffer material is interposed between the holder and the slide tube to prevent the slide tube from dropping suddenly.

(Function) When the ball body of the engaging body provided on the holder is urged toward the outer circumferential surface of the slide tube by the urging force of the elastic body and engages with the groove provided on the outer circumferential surface of the slide tube, the slide tube absorbs the engagement force. The slide is suppressed by In addition, if the slide tube is manually slid upward or downward against the above-mentioned engagement force,
The ball, which had fallen into the groove and was engaged, retreats and is released from the engagement, allowing the slide tube to slide up and down.

(Effects of the invention) As described above, in the present invention, the slide tube and the holder are engaged by dropping the ball body of the engaging body into the groove of the slide etc. by the biasing force of the elastic body. Therefore, by setting the biasing force of the elastic body to an appropriate strength in advance, it is possible to slide the slide tube without having to operate the handle to release/engage the engagement means as in the conventional case. The height of the water discharging body can be easily adjusted, and furthermore, the height adjustment position can be intuitively known by the feel of the ball as it falls into the groove, making it very convenient to use.

(Example) An example of the present invention will be described below based on the drawings.
