Specifically, the twisting degree of the cable 3 may be different between the seal block body 6a on the foremost side and the pipe port 4 side, but the seal block body of the high-performance pipe port water stop device 1 for the CVT cable of the present embodiment. Since the long holes of the block bolt insertion holes 11 of 6b and 6c are formed as long holes in the circumferential direction as they are arranged on the rear side, the foremost side corresponding to the twisted state of the cable 3 is formed. The seal block bodies 6b and 6c other than the seal block body 6a rotate more on the side of the pipe port 4 side, and the cable 3 and the seal block bodies 6b and 6c are brought into close contact with each other to prevent water leakage from the pipe line 2 more completely. can do.

  In S7, in the state in which the CVT cable high-function conduit port water stop device 1 is inserted into the conduit port 4 of the conduit 2 through the conduit port insertion process, the clamp plate bolt insertion hole 13 and the block body bolt insertion hole 11 are inserted. By firmly tightening the tightening bolts 8, the seal block body 6 is press-contacted via the tightening board 7 (see FIG. 9).
