PROBLEM TO BE SOLVED: To miniaturize a device for positioning a coupling sleeve.SOLUTION: A spherical body 4 as a wedge member is disposed movably in an axial line direction of a device body 2 and immovably in a direction orthogonal to the axial line in a storage hole 2e of the device body 2. A male screw member 7 is threadedly engaged with the device body 2 and the sphere body 4 is pushed against a top end surface of the male screw member by a compression coil spring 6. In the device body 2, a pressing member 8 which penetrates a circumferential part of the device body and of which the inner end part comes in contact with the spherical body 4 and of which the outer end part is protruded outside from the device body 2 is disposed immovably in the axial line direction of the device body 2 and movably in the radial direction. When the sphere body 4 is moved rightward with the male screw member 7, the sphere 4 moves the pressing member 8 outward. The pressing member 8 strikes against an annular protrusion part E1 of a coupling sleeve E and positions the coupling sleeve E with respect to the axial line direction and the direction orthogonal to the axial line. |
