One locking pawl 4 is rotatably and pivotable attached to the locking member 6 via a pivot pin 11, the locking pawl 4 can pass the opening 3 of the main drainage 2 by revolving the pivotably attached locking pawl 4. The locking pawl 4 is prevented from revolving by screwing the connecting member 9 to the locking member 6, and the locking pawl 4 can not pass the opening 3 of the main drainage 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
