<p>PROBLEM TO BE SOLVED: To surely fit an insertion hole of a mounting lever to a position of a screw section of a mounting shaft and to prevent position slippage between the insertion hole and screw section. SOLUTION: A mounting shaft 15 is projected to the outside of a post 1, and a mounting lever 4 is inserted in the mounting shaft 15 to make the post 1 at right angles to the mounting lever 4 to assemble. A groove section 18 is formed over the overall length in the mounting shaft 15, a screw section 24 for screwing a countersunk screw 23 is formed inside the groove section 18, and when the mounting lever 4 is inserted in the mounting shaft 15, an insertion hole 31 of the mounting lever 4 is moved along the groove section 18, and the insertion hole 31 is always positioned on the screw section 24. For that purpose, the screw section 24 is surely fitted to the insertion hole 31 in a state to push the end section of the mounting lever 4 against the outside of the post 1.</p> |
