<P>PROBLEM TO BE SOLVED: To provide an operation unit of a release wire, which can be smoothly operated to be pushed/pulled, even in a small-depth space of the operation unit. <P>SOLUTION: A remote-control drain valve device employs a release wire that comprises an outer tube 31 and an inner wire 32 for being inserted into the outer tube 31 to be capable of being pushed/pulled therethrough. A curved or spiral guide hole 11 for changing a direction by guiding sliding of the inner wire 32 is formed inside a rotary operation member 1 to which an end of the outer tube 31 is fixed, so that the inner wire 32 sliding through the guide hole 11 of the operation member 1 can be pushed/pulled by changing an operation direction by the operation of pushing/pulling an end of the inner wire 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
