摘要： 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).

摘要： A plug portion (27) is projected from a first block (1) so as to be inserted into a insertion hole (5) opened in a second block (2). A support surface (9a) is formed on the first block (1) so as to be brought into contact with a supported surface (2a) formed on the second block (2). In the support surface (9a) is opened a fluid flow hole (59). A gap supporting member (K) acting force upon the second block (2) in such a direction as to separate the second block (2) from the first block (1) so as to form a gap (G1) between the supported surface (2a) and the support surface (9a) is provided on the first block (1). A pull member (21) eliminates the gap (G1) by making the second block (2) approach the first block (1) against the force of the gap supporting member (K) in such a condition that an outer peripheral surface of the plug portion (27) is in close contact with an inner peripheral surface of the insertion hole (5) to bring the supported surface (2a) into contact with the support surface (9a).
