And the locked portion 33 are evenly frictionally locked at a plurality of locations, so that the height of the support cylinder 22 and the slide cylinder 32 can be set in a stable state. With this configuration, in a state where the support cylinder 22 and the slide cylinder 32 are in a stable state, the locking portion 33 is moved to a desired position by sliding against the locked portion 24 against friction. The height is easily adjusted because the sliding movement is stopped later to frictionally lock.

  The pedestal 1 of the present invention having the above-mentioned structure is made of a known and publicly used material used as a pipe support of this kind, such as a metal such as stainless steel, cast iron steel having a galvanized finish, a synthetic resin such as a polypropylene resin or an ABS resin.

The height of the pipe support 6 supporting the pipe P with respect to the wall surface 4 is reliably supported and fixed without changing.
Further, when the locking portion 24 is loosely engaged with the locked portion 33 so as to allow backlash, the loose friction locking configuration may cause vibration and vibration of the pipe P. (Water hammer phenomenon, shaking by earthquake, etc.). In particular, when mounted on the wall 4, the pedestal 1 of the present invention is surrounded by the sound absorbing material and the heat insulating material 5, so that when the pipe P vibrates or vibrates, the above-mentioned loose friction locking structure is used. The cushioning function of the sound-absorbing material / heat insulating material 5 is added to the cushioning function of the above, and a synergistic effect of exhibiting a double shock absorbing function is produced.
