Reference numeral (21) is a support shaft, with the fitting insertion portion (17) of the mounting portion and the fitting insertion portions (20A) and (20B) of the support body arranged linearly as shown in FIG. The fitting part (15) and the support base part (19) are fitted into the insertion part so as to be rotatable and integrated.

FIG. 2 schematically shows the arrangement of the support shaft (21) with respect to the respective fitting insertion parts (17) (20A) (20B), and FIG. 3 shows the configuration of the end of the support shaft (21). FIG. 3B is a cross-sectional view showing the side of the fitting insertion portion (20A). As can be seen from these figures, the support shaft (21) is formed as a quadrangular prism and has a dimension longer than the fitting insertion portion (17) of the attachment portion (15).
As shown in FIG. 2 and FIG.
A) It is arranged in the (20B) so as to project. Further, screw holes (30) are formed on the end faces of both ends of the support shaft. (3
Reference numeral 1) is a ring-shaped stopper that is fitted into the spindle (21) from the open end of the fitting insertion portion (20A) and abuts on the end portion of the fitting insertion portion (17). (32) is a cylindrical elastic bush made of urethane rubber, and as shown in FIG. 3, has a dimension longer than the dimension protruding into the fitting insertion portion (20A) of the support shaft (21). Therefore, when fitted into the tip of the support shaft (21), the elastic bush (32) projects from the support shaft (21). (33) is a screw hole (30) of the support shaft through a washer (34) that abuts the end surface of the elastic bush.
It is a screw that is screwed into. As described above, when the screw (33) is tightened while the elastic bush (32) is protruding from the tip of the support shaft (21), the elastic bush (32) is locked by the support shaft (2).
Although it is compressed in the longitudinal direction of 1) and its outer surface tries to bulge into a barrel shape as shown by the alternate long and short dash line in FIG.

It rotates counterclockwise in FIG. 5 about the support shaft (21) shown in FIG. 1 to the state shown in FIG. In this state, the terminal portion (9) faces upward of the cabinet (1), so that a worker can touch the terminal portion (9) from the front of the television receiver, and the connection cable of the external device can be connected to the terminal. It can be connected to the part (9).

When the terminal box is rotated, since the support shaft (21) is in the braking state and cannot freely rotate as described above, the terminal box slowly rotates with a heavy feeling and the state shown in FIG. Leading to. In this state, the turning force in the clockwise direction acts on the figure due to the weight of the terminal box, but since the support shaft cannot rotate freely, the operator does not suddenly rotate and the operator suddenly squeezes his or her finger. I don't have to worry. Further, when the connection to the terminal box is completed, the terminal box (50) is pushed clockwise toward the rear of the cabinet to rotate the terminal box clockwise in FIG. Return to the state shown. In this case, the connecting cable is not seen from the front of the cabinet, so that the appearance is not spoiled.
