In these figures, (1) is a cabinet accommodating a television main body (not shown), in which the left side is the front surface and the right side is the rear surface. (3) is a terminal box accommodating part formed at the rear of the upper surface of the cabinet, and (4) is a fixing part (3) formed substantially at the center of the front end of the terminal box accommodating part.
A support body fixed to the 1) by screws (32), the upper end of which is located near the top surface (11) of the cabinet and the 4th
As shown in the overall structure of the figure, it comprises a support base (41) and a pair of fitting parts (42) (43) located at the upper end thereof. (5) is the fitting portions (42) and (43) of the support
A support shaft that is fitted over the support and supported by the support, and (6) is a mounting member that is rotatably fitted on the support shaft between the pair of fitting portions (42) and (43) of the support. Mating part to be mated (61)
And a plate-shaped mounting portion (62) extending from the fitting portion. Reference numeral (7) is a terminal box, which is composed of a case (71) fixed to the mounting portion by screws (8) and a cover (72) attached to the case.
(9) is a printed wiring board (not shown) mounted in the terminal box
The terminal portion provided on the housing is configured to project outward from the cover (72) so that a connection cable of an external device to be connected to the TV body can be connected without removing the cover (72).

Further, (100) is a locking device for locking the terminal box, and is a pair of protrusions provided at the upper end of the support base (41) in the vicinity of the fitting portion (61) of the mounting member and spaced from each other. (101) and (102), both ends of which are respectively supported by these protrusions, and the elastic support rod (103) and the support rod are fitted to approximately the center of the support rod so that they can rotate. A roller (104), a pair of restriction pieces (105) (106) provided on the base of the support body for position restriction so that the roller does not move in the longitudinal direction of the support rod, and a mounting member corresponding to the roller. And a protrusion (107) provided on the fitting portion (61).

The size of the protrusion (107) up to the tip is set slightly larger than the shortest distance between the fitting part (61) and the roller (104), and the terminal box (7) rotates. The protrusion (107) is located between the roller (104) and the support base (41) in a state in which the terminal (9) is moved to face the upper part of the cabinet, that is, in the state of FIG. 2 or 3. Is being done. In this state, the terminal box (7) is pushed downward, and even if a clockwise rotational force is applied in FIG. 3, the projection (107) comes into contact with the roller (104) and cannot rotate, so that the terminal box (7) cannot rotate. (7) is in a locked state.

However, when the terminal box (7) is pressed in the clockwise direction in FIG. 3 with a little strong force, the support bar (103) of the roller bends downward as shown by the alternate long and short dash line in FIG. Rotates the roller (104) counterclockwise from the state shown in FIG. 3 to get over the roller (104) and reach the left side thereof.
