The sliding member 5 is rotatably inserted into a through hole opened at the center of an annular rotating guide groove 14 formed on the cover member 11 side. The rotation receiving seat 9 is integrally attached to the base 1 side and fixed by the screw 13b. The slider 6 is formed in a ring shape from a material that is easily slidable in order to smoothly rotate the display body 2 in the left-right direction.
The rotary guide groove 14 is inserted and set along a circumferentially upright outer wall surface.

The sliding plate 7 is formed in an annular shape using a lubricating resin which is easily slidable in the same manner as the sliding member 5, and is slidably set in the rotation guide groove 14. . The rotation receiving seat 8 has a configuration in which a lower member 15, a rotation plate 9, and an upper member 16 are vertically arranged and assembled.
In this embodiment, the lower member 15 and the rotating plate 9 are
The upper member 16 and the lower member 15 are screwed by screws 13b 'and the like, respectively. The upper member 16 functions as a support bracket when the display body 2 is rotated in the vertical direction. Therefore, a fixed shaft 21 described later is rotatably inserted into the upright portions on both sides. A shaft hole 16a is formed. A through hole is also formed in the rotation receiving seat 8 in the up and down direction, and a cable 17 for electrically connecting the base 1 and the display main body 2 passes through the through hole and the like in the same direction. It has been inserted.

As shown in FIG. 3, the tilt mechanism 4 includes a fixed arm 18 provided at a lower portion of the display main body 2 and a base 1.
