ジ１２とにより構成する。As shown in FIGS. 1 and 2, a universal joint according to the present invention has a metal joint case 2 having one end fixed to a pole 1 extending vertically from a column (not shown). A cavity 3 formed at the other end of the case 1; a hole 4 formed at the bottom of the cavity 3; and a long groove 5 formed at the top of the cavity 3 and extending in a longitudinal direction and having a predetermined length and depth. A plate-shaped body 6 having a shape conforming to the shape of the long groove 5 loosely fitted in the long groove 5; and a disk-shaped spherical receiving seat 8 screwed into the hole 4 and having a through hole 7 in the center thereof. And a spherical portion 9 disposed in the hollow portion 3 so as to be interposed between the spherical receiving seat 8 and a portion closer to the other end side from the lower surface center of the plate-like member 6; Connected to the outside of the joint case 2 through the through hole 7 of the spherical receiving seat 8. A ball shank 10 extending and formed in the joint case 2, a screw hole 11 communicating with one end of the elongated groove 5, constituted by a screw 12 to be screwed into the screw hole 11.

接固定できるようになる。Since the universal joint according to the present invention has the above-described structure, when the screw 12 screwed into the through hole 11 is loosened, the universal joint between the spherical receiving seat 8 and the lower surface of the plate-like body 6 is removed. The spherical part 9 inserted into the ball shank 1 can be freely rotated in the joint case 2.
0 can be positioned in any direction with respect to the joint case. From this state, if the screw 12 is tightened and one end of the plate-like body 6 is pressed, the plate-like body 6
Is tilted with the other end of the long groove 5 as a base point, and a portion closer to the other end than the center of the lower surface of the plate-like body 6 strongly presses the top of the spherical body 9 downward by the principle of leverage. The spherical body 9 can be pressed and fixed between the spherical receiving seat 8 and the plate-like body 6.
