(57) drain plug unit (4) including a connecting bar (11) having a hole (14) in a position slightly remote from the center in the longitudinal direction thereof toward one end (11b) on the side opposite to the other end (11a) in the longitudinal direction thereof, a holding member (7) connected to the other end (11a) of the connecting bar (11), and a plug member (5) connected to the hole (14) by means of a ring (16) and removably fitted into a drain outlet (3). The plug member (5) is pulled out from the drain outlet (3) when extremely small pulling force is applied to the holding member (7) and hence the one end (11b) of the connecting bar (11) is caused to abut against a fixed position (2b) adjacent to the hole (14)
