PROBLEM TO BE SOLVED: To provide a remote-operated drain plug device that may be used without physically connecting an operation body and an operation transfer member, and without using electricity, etc.SOLUTION: A remote-operated drain plug device comprises an exhaust port 1a provided on a tank body, a valve member 2 that opens/closes the exhaust port 1a by moving vertically, an operation part 4 fixed on the exhaust port 1a and having an actuation part that moves the valve member 2 vertically and an operation body 5a operated by a user for opening/closing the exhaust port 1a, and an operation transfer member that transfers an operation made on the operation body 5a to the actuation part. The operation transfer member is not physically connected with the operation body 5a, and has magnets 11, 12 on either or both of an edge part on the operation part side of the operation transfer member or/and the operation body 5a. The operation transfer member is actuated by magnetic force of the magnets 11, 12 in accordance with an operation made on the operation body 5a, and transfers stress on the actuated operation transfer member to the actuation part and lifts/lowers the valve member 2, thus opening/closing the exhaust port 1a.SELECTED DRAWING: Figure 2 |
