However, if the lid is fixed and held open, even if the lid is accidentally stepped on, the lid can be smoothly lowered without any injuries and the foot may be injured. In addition, the lock mechanism (fixed holding mechanism) and the tip of the operating wire are not damaged and the opening / closing function of the stopper lid is not deteriorated or lost. The safety is high and the structure of the lock mechanism is extremely simple. Another object of the present invention is to provide a remote-operated drain faucet opening / closing device having features such that the protruding portion of the switch can be housed inside the opening of the housing cylinder when the rotary operation switch is not operated.
