A tubular part 12 into which a head 21a of the cylinder 21 is fitted is provided on a rear surface of the base 11 and a supporting wall 13 is erected in a rear end of the base 11. In the supporting wall 13, a through hole 14 through which a metal rod 18 to be inserted is formed at such a height position that a lower end of an outer circumference of the through hole 14 becomes equal to a standard level of a surface of the base 11, the metal rod 18 fitting the distal end thereof into a horizontal hole 3 formed by cutting a bed-sill 2. A flat insert panel 15 to be inserted between the bed-sill 2 held up to a predetermined height and a foundation 1 is provided while extending backwards from the supporting wall 13. |
