定角度傾斜している。従って、係止体１０は水平方向に
可動できる。As shown in FIG. 2, the locking body 10 has a wide portion 10a having a width 1 into which the spherical portion 11a at the tip of the locked body 11 can be inserted.
And a narrow portion 1 having a width 2 narrower than the diameter of the spherical portion 11a.
It is formed into an elongated ring shape consisting of 0b and
The wide portion 10a is attached to the wall 3 by the metal fitting 12. The end portion 10b 'of the narrow portion 10b is inclined at a constant angle toward the room 2 side. Therefore, the locking body 10 can be moved in the horizontal direction.
