<p>PURPOSE: To eliminate the disturbance of a leg when used by wall-mounted or ceiling-mounted by inserting the leg which is rotated at a support shaft provided at a unit body as a center with the containing recess of the body. CONSTITUTION: A leg 3 is rotatable at a support shaft 1a. When the leg 3 is closed, protrusions 3b are pressed by the inner wall of a unit body 1, and when the protrusion 3b of the leg 3 is further moved to the position of a recess 1b contained in the body 1, the protrusion 3b is externally pushed out, and the leg 3 can be locked in the body 1 in the locked state. When the leg 3 is opened, a force of opening direction is given to the leg 3 by a hand to press the protrusion 3b by the inner wall of the body 1, and hence the leg 3 can be moved at the position out of the body 1. Thus, when the leg 3 is once drawn, the leg 3 can be opened.</p> |
