DRAIN VALVE DEVICE, WASHING WATER TANK DEVICE WITH THE DRAIN VALVE DEVICE, AND WATER CLOSET WITH THE WASHING WATER TANK DEVICE
PROBLEM TO BE SOLVED: To provide a drain valve device capable of improving installing performance, restraining variance in an amount of washing water and occurrence of wasteful water, and saving water.SOLUTION: A drain valve device 8 includes: a body part 18 having a drain port part 14 attached to a drain port 6b formed on a washing water tank 6, and a valve element 38 for opening and closing the drain port part 14; and a cylindrical body 20 attached to the body part 18 and freely selectable in accordance with the specification of the washing water tank 6. The cylindrical body 20 includes a lower opening part 46 attached to the drain port part 14 of the body part 18 attached to the washing water tank 6, and a side wall part 50 protruding to an outer peripheral side from the lower opening part 46 and then surrounding the body part 18, and intrusion preventing means for preventing washing water outside the cylindrical body 20 from intruding into the cylindrical body 20 through an attachment part 54 is formed on the attachment part 54 of the cylindrical body 20 attached to the body part 18.SELECTED DRAWING: Figure 4
【課題】組み付け性を向上させることができると共に、洗浄水量のばらつきと無駄水の発生を抑制し、節水化を実現することができる排水弁装置を提供する。【解決手段】排水弁装置８は、洗浄水タンク６に形成された排水口６ｂに取り付けられる排水口部１４及びこの排水口部１４を開閉する弁体３８を備えた本体部１８と、この本体部１８に対して取り付けられて洗浄水タンク６の仕様に応じて選択自在な筒体２０と、を有し、この筒体２０が、洗浄水タンク６に取り付けられた本体部１８の排水口部１４に取り付けられる下側開口部４６及びこの下側開口部４６から外周側に突出した後に本体部１８を取り囲む側壁部５０を備え、本体部１８に取り付けられる筒体２０の取付部５４に、筒体２０の外部の洗浄水が取付部５４から筒体２０の内部に浸入することを防止する浸入防止手段が形成されている。【選択図】図４
