Claims (1)

[Scope of utility model registration request] A valve body for opening and closing the drain port and a push-up lever for pushing up the valve body to a required height are respectively disposed within the drain passage, and an operating mechanism for the push-up lever is disposed outside the drain passage, and The tip of the operating wire, which has a push button on the base end side and is biased by a returning spring to return the push button to its original position, faces the operating mechanism, and when the push button is operated, the tip of the operating wire is pressed. This is a drainage device for a wash basin, etc., configured to operate an operating mechanism, and this operating mechanism includes a locking/disengaging regulating body provided around the inner wall of the cannula, and an inner part that can freely move forward and backward toward the proximal end of the cannula. an engaging/disengaging element which advances and retreats when engaging and disengaging with the engaging/disengaging regulating body loosely fitted into the cannula on the front side of the engaging/disengaging body; and a proximal end inserted into the cannula and the other protruding end. It is composed of a connecting actuating body that is connected to the actuating member of the push-up lever and that can move forward and backward, and a returning spring that is installed in the cannula and biases the connecting actuating body to retreat toward the proximal end. A drainage device for a washstand, bathtub, etc., characterized in that the tip of the operating wire is arranged on the back of the engaging/disengaging body of the operating mechanism.
