The retaining clip 14 has a substantially C-shaped planar shape and is formed of a pair of elastic arm parts 15a, 15b of a symmetric circular arc shape for holding an upper end male screw part 3 of a waist pipe 1 and a connection part 16 connecting the elastic arm parts. A recessed groove part 19 with which a base 7a of the pin is fitted is formed below the connection part 16. When the base 7a of the pin fitted with the recessed groove part 19 is fixed to the connection part 16 by a binding band 23, and the pin 7 is inserted over a pin hole 5 and a long hole 6, the elastic arm parts hold the upper end male screw part 3 of the waist pipe 1 and both end parts of the pin 7 are held in direct contact with a top face 4a of an adjustment female screw body 4. |
