<p><P>PROBLEM TO BE SOLVED: To provide a structure for improving the sealing performance of a reinforcement connection device between a joint and a reinforcement and preventing the fall of a sealing member. <P>SOLUTION: The sealing structure 6 seals a space between the end inner periphery of the reinforcement connection cylindrical joint 5 and the outer periphery of the reinforcement to prohibit the leakage of a filler filled inside the joint 5. The sealing structure 6 includes the rubber annular sealing member 10, and a C-shaped steel holding ring 20. The sealing member 10 has an annular base part 11 to be fitted into a mounting groove 5a in the end inner periphery of the joint 5, and annular collar parts 12, 13 extending from th base part 11 inward in the radial direction. The holding ring 20 is stored in the base part 11 of the sealing member 10 and disposed inside of an outer peripheral portion 11a of the base part 11. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
