Then, by rotating the rotating fitting 14 with respect to the base portion 12, the rotating protrusion 3 is rotatable in a direction indicated by an arrow D about the center M of the rotating fitting 14 shown in FIG. A pin hole 7 through which the joining pin 8 (FIG. 1) is inserted is formed substantially at the center in the length direction of the rotary projection 3. Here, the joining pins 8 widely include, for example, screws, bolts, and the like. In the embodiment shown in FIG. 2, a positioning projection 10 wider than the rotation projection 3 is continuously formed at one end in the length direction of the rotation projection 3. The positioning projection 10 functions to position the rotary projection 3 in the mounting groove 5 of the fixing bracket 4 described later.

On the other hand, a fixture 4 is fixed to the wall 1a. A mounting groove 5 having a substantially U-shaped cross section is formed on the front surface (the surface opposite to the wall 1 a) of the fixing bracket 4. The mounting groove 5 is formed in such a size that the rotary protrusion 3 can be slidably fitted. A screw hole 15 is formed on the back side of the fixture 4 and is fixed to the wall 1a with a screw. In this embodiment, the fixture 4 is fixed to the wall 1a with the mounting groove 5 oriented in the vertical direction (perpendicular to the plane of FIG. 1). At the upper end of the mounting groove 5 in the vertical direction A, a positioning recess 9 wider than the mounting groove 5 is continuously formed as shown in FIG. The positioning concave portion 9 is formed in a shape in which a positioning convex portion 10 provided at one end of the rotating protrusion 3 can be slidably fitted, and when the rotating protrusion 3 is fitted into the mounting groove 5. In addition, the rotation projection 3 is positioned in the mounting groove 5 by fitting the positioning projection 10 into the positioning recess 9.
