<p>PURPOSE:To restrain the vibration of the end of an inner pipe due to fluid pulsation by providing a seal ring which forms a curtain between a flexible hose body and the flexible inner pipe inserted into the body and a locking member, which has a positioning portion in contact with the inner periphery of the hose body, in the vicinity of the end of the inner pipe. CONSTITUTION:A hose 1 comprises a flexible hose body 11 and a flexible spiral pipe 12 inserted into a hole 11a, having a seal ring 13 which forms a curtain between the inner periphery of the hose body 11 and the outer periphery of the spiral pipe 12 and a pair of locking members 14, which have three positioning portions 141 on the inner periphery of the hose body 11, n the vicinity of the end of the spiral pipe 12. Therefore, even if oil is pulsated to cause pulsation in the hose 1, the pulsation is restrained by pressure propagation in a cavity 18 and reflecting operation on both end faces of the seal ring 13. Also, even if the spiral pipe 12 is intended to be largely vibrated at the end, the positioning portion 141 has moderate flexibility to restrain the vibration of the spiral pipe 12 at the end.</p> |
