Abstract

PROBLEM TO BE SOLVED: To cause a clamping bolt, bringing a wedge member into a state to bite in a flange, to have a function to release the wedge member from the flange. SOLUTION: A clamping bolt 24 is rotatably inserted in a fit-in state in a hole 20 formed in a wedge member 18. When, with this state, the clamping bolt 24 is screwed in a screw hole 22 formed in the flange 14a side, the wedge member 18 is fixed on the flange 14a side with a pressure and by the pressure of the wedge member 18, the flange 14a is fixed on a shaft body. A flange 24b is formed on the shaft part of the clamping bolt 24, the two surfaces of the wedge member 18 are rotatably nipped by the flange 24b and the head part 24a of the clamping bolt 24 and the wedge member 18 is axially interlocked with the clamping bolt 24.

In the above-described friction fastening device using the conventional wedge method, once the wedge member (2) bites into the flange (4), the fastening cannot be easily performed. In this case, as shown in FIG.
The bolt (13) for releasing the fastening is screwed into the tap (2b) of the wedge member (2), and the tip of the bolt (13) is pressed against the wall surface of the groove (6) on the flange (4) side. A common method is to remove the wedge member (2) from the groove (6) by a reaction force of the bolt (13) against the wall surface of the groove (6). However, according to this method, there is a problem that a bolt to be newly inserted into the extraction tap is required, so that the cost is increased, and a mounting dimension of the bolt to be inserted into the extraction tap and a work space are required. An object of the present invention is to solve the above problems.
