<p><P>PROBLEM TO BE SOLVED: To realize the shape for stabilizing the shape of an O-ring with a pipe material itself at low manufacturing cost. <P>SOLUTION: This pipe 30 with double bead is inserted into a connection hole 114 formed on a mating member 12 at its pipe end part 32, an antislip-off member 51 is fixed to the mating member 112 in this condition to prevent the pipe end part from being slipped off from the connection hole 114. The pipe end part 32 of the pipe 30 is provided with a large bead 42 having an outer diameter slightly smaller than an inner diameter of the connection hole 114, and a small bead 43 mounted at a side far from the pipe end with respect to the large bead 42, and the small bead 43 is abutted and fixed on the antislip- off member 51. <P>COPYRIGHT: (C)2003,JPO</p> |
