ABSTRACT:
A connector is inserted into a connection hole provided on a fluid piping equipment, and the connector is prevented from dropping out via a retainer held by a retainer holding portion. The connector has a connecting portion including a flange stop portion, and a positioning means is disposed between the connecting portion and the fluid piping equipment. This positioning means is to position the connecting portion in a circumferential direction so as not to rotate relative to the connection hole and has a mounting angle adjusting function capable of positioning the connecting portion in the circumferential direction selectively at any one of a number of mounting angular positions relative to the connection hole. An annular surface on the other end in the axial direction of the stop portion is formed in a taper shape tapered toward the other end in the axial direction.
