<P>PROBLEM TO BE SOLVED: To rotatably connect hoses in a coming-out preventive manner by a simple structure. <P>SOLUTION: By inserting the connection end H1 of the hose H inserted with the external peripheral face of a nipple 1 into a pressing cylinder 2 and fastening the end in the radial direction by the pressing cylinder 2, the outside of an accommodation recess 1b is covered with the pressing cylinder 2 even if the connection end H1 of the hose H is compression-deformed and the external periphery of a tip face H2 is protruded toward the accommodation recess 1c, a protruded bead H3 of the hose H is not protruded toward a connection cylinder 3, and thus the contact of the hose and the connection cylinder 3 can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
