The operation transmitter 2 consists of a first flexible wire portion 11 whose front end 11a abuts on a lower end 1b of a valve shaft 1a of the valve element 1 to knock it up, and a second flexible wire portion 12 connected to the operation part 10. A connection means 30 is provided outside the drain pipe 20 communicated with the drain port A for detachably connecting the first wire portion 11 to the second wire portion 12. A resilient member 33 is provided on the first wire portion 11 for resiliently energizing the first wire portion 11 toward the outside at all times. COPYRIGHT: (C)2009,JPO&INPIT
