Abstract
A plug member (12) inserted into a positioning hole (5) formed in a second block (2) is projected from a first block. Two slide portions (61, 61) opposed to each other across the plug member (12) are arranged around the plug member (12) movably in a first radial direction (D1) substantially orthogonal to the opposed direction. An annular pressing member (15) which is allowed to diametrically expand and diametrically contract is arranged around an outer periphery of the slide portion (61, 61). The slide portions (61, 61) diametrically expand the pressing member (15) in a second radial direction (D2) which is the opposed direction by a drive device to press the pressing member (15) against an inner peripheral surface of the positioning hole (5), by which the slide portions (61, 61) are moved in the first radial direction (D1) with respect to the plug member (12).
