Reference numeral 4 denotes a lower end portion of the L-shape, which is rotatably supported by a rotating shaft 53a provided below the vertical wall of the first mounting bracket 53. On the left and right side surfaces of the second mounting bracket 54, an arc-shaped long hole 54a centering on the rotation shaft 53a is formed, and an L-shaped tip is formed on the arc-shaped long hole 54a and the upper part of the vertical wall of the first mounting bracket 53. It is formed so as to be screwed by a screw 53b provided in the portion. The suspension member 2 formed of a cylindrical pole or the like is attached to a mounting hole provided on the upper surface of the mounting bracket, and is installed on the ceiling 52 or the like.
With the above configuration, the rotation shaft 53a is centered on FIG.
By moving the display device 51 in the direction of the arrow described in (b),
The screen 53 is tilted and the screw 53b is tightened and fixed at an easy-to-view angle.

The thickness of the conventional first mounting bracket 53 and the second mounting bracket 54 in the front-rear direction is at least a circle in order to pivotally support the L-shaped second mounting bracket 54 so as to rotate. At least a thickness corresponding to the arc-shaped long hole 54a was required, and it was difficult to make the entire installation device thin and compact. Therefore, even if a thin plasma display is used, there is a problem that the entire device becomes large, and the advantages of the thin flat display device cannot be fully utilized. When the display device 51 is large and heavy,
Since the weight is added to the tilt portion, there is also a problem that the mounting of the display device and the setting of the tilt angle are both difficult.
