PROBLEM TO BE SOLVED: To provide a remotely-operated drain plug system, which accomplishes flangelessness of an operation part, allows no accidental operation to occur, and is improved in design, cleanability, and hygiene, where the remotely-operated drain plug system is required to have a front-side surface of the operation part to be about the same level with a front-side surface of the surrounding of a through-hole.;SOLUTION: An operation part of a remotely-operated drain plug system, which remotely opens and closes a drain port arranged on a bottom face of a tank, is composed of: a through-hole arranged on a wall surface; an operation part body 1 that is fitted on the reverse-side face of the surrounding of the through-hole; an operation shaft support part 2 that is contained and fixed inside the operation part body 1; an operation shaft 2a, which is fitted to the operation shaft support part 2 in such a way that it freely moves in and out to open and close the drain port; a button part member 3 that is installed at the end of the operation shaft 2a; and a position-adjusting mechanism for performing fixation such that the front-side face of the button part member 3 in a stationary state with the drain port opened or closed is at about the same level with the front-side face of the surrounding of the through-hole.;COPYRIGHT: (C)2013,JPO&INPIT
