PURPOSE:To expansively enable adjustment of an inclination to the vertical direction and adjustment of a lateral directional turning angle, and eliminate the occurrence of a dead angle by putting a part of a ball joint in a condition of projecting outside of an outside surface of a support plate. CONSTITUTION:A back board 2 is installed on the reverse of a mirror M, and a support plate 3 whose side view is bent in a triangle shape is fixed to the obverse of this back board 2. Two inclined faces are formed on the support plate 3 of a triangle in a side view, and a locking hole 4 is bored in one inclined face. A ball joint 5 inserted from the reverse side of the support plate 3 is fitted in the locking hole 4 of this support plate 3, and a straight line-shaped suspending rod 9 is connected to the ball joint 5. When a part of the ball joint 5 is put in a condition of projecting outside of an outside surface of the support plate 3, the mirror back board 2 can be changed in a large angle range to the straight line-shaped suspending rod 9. Thereby, even if the mirror M is suspended from the ceiling, it can be supported without generating a dead angle. |
