Claims

[Scope of utility model registration request]

A protruding arc-shaped surface that collides with the inner surface of the post mounting hole 6 when inserted into the post mounting hole 6 provided in a base etc. is attached to the lower part of the vertical bar 11 having a threaded portion 12 formed on the upper side. a pair of abutting members 16 having 17;
, 16 are configured such that they can rotate in an arc in the vertical direction with the arcuate surfaces 17 facing outward to the left and right, respectively, about the vertical bar 11, and the arcuate surfaces of the abutting members 16, 16 17, 17 is the vertical bar material 11
When the vertical bar 11 is rotated arcuately from above to below, the vertical bar 11 is moved from a state in which the distance between the two arcuate surfaces 17, 17 at the maximum part in the orthogonal direction is smaller than the inner diameter of the column mounting hole 6. The arcuate surfaces 17, 17 are further biased in a direction in which the arcuate surfaces 17, 17 are rotated in an arc from above to below. A joint main body 1 that is pivoted, a pedestal 2 having a hole 21 through which the vertical bar 11 of the joint main body 1 is inserted vertically and having an area that can cover the upper part of the column mounting hole 6, and the joint main body 1. By inserting the lower part of the main body 1 into the support mounting hole 6 and inserting the pedestal 2 into the vertical bar 11, the vertical bar 11 is screwed into the threaded portion 12 of the vertical bar 11. a screw member 3 that acts to move the screw upward relative to the base 2;
and a connecting member 4 for connecting the lower end of the support 8 to the upper side of the vertical bar 11.
