Abstract
A plug member (12) inserted into a positioning hole (5) formed in a second block (2) is projected from a first block (1). A plurality of slide portions (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 thereof. A first pressing member (15) and a second pressing member (19) are arranged outside the slide portions (61) diametrically expandably and diametrically contractibly and axially movably. The first pressing member (15) is driven toward a base end by a drive device, whereby the slide portions (61) expand the first pressing member (15) via the second pressing member (19), thereby the slide portions (61) are moved in the first radial direction (D1) with respect to the plug member (12). After the movement, when the second pressing member (19) is blocked from moving toward the base end, the first pressing member (15) strongly presses an inner peripheral surface of the positioning hole (5) in the second radial direction (D2).
