<p><P>PROBLEM TO BE SOLVED: To close a gap arisen between the periphery of a pipe and a hole of a grinding material recovery box into which an end of the pipe is inserted in an apparatus for grinding the inside of the pipe. <P>SOLUTION: One end of a flexible tube member 5 of which both the ends are open is fixed to the grinding material recovery box 1 so as to be concentric with the hole 11 of the recovery box 1; a pipe P is inserted from the free end side of the tube member 5 into the hole 11 of a mate member (10); and the tube member 5 is twisted by turning the free end of the tube member 5 in the circumferential direction of the pipe P to fasten the pipe P with the tube member 5 to bring the inside surface of the tube member 5 into tight contact with the pipe P. Thereby, the gap S between the pipe P and the hole 11 is closed, and a grinding material is prevented from leaking out through the gap S. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
