发明名称 OPENING SEAL STRUCTURE OF TRANSPORT PIPE
摘要 <P>PROBLEM TO BE SOLVED: To provide an opening seal structure of a transport pipe capable of surely preventing leaking-out of fluid from an opening with a simple structure in a state of inserting a rope body into the transport pipe via the opening. <P>SOLUTION: A seal body 5 constitutes the seal structure 1, and can block up the opening 3 of a gas pipe 2 in a state of sandwiching a hose 4 since an insertion hole 8 is formed for inserting the hose 4 in an elastically-repulsively sandwiched state by penetrating along the axis. Thus, even if inserting the hose 4 inside from the outside of the gas pipe 2 via the opening 3, leaking-out of transported gas can be prevented by blocking up the opening 3 by the seal structure 1. Thus, a worker can perform work in the gas pipe 2 by using the hose 4, and can also prevent the leaking-out of the fluid. <P>COPYRIGHT: (C)2006,JPO&NCIPI
