PROBLEM TO BE SOLVED: To provide a water saving device for shower equipment that saves hot water during the time of using a shower and automatically discharges hot water remaining in a shower head to the outside at the time of finishing using the shower.SOLUTION: A water saving tool 2 comprises: a first cylindrical body 30 in which a first water conduction hole is provided; a second cylindrical body 35 whose inner part is hollow; and a water saving plate 38 including a second water conduction hole for opening or closing an aperture of the first water conduction hole in a predetermined range to transmit water. The water saving plate 38 and a closing wall 31 surface of the first cylindrical body 30 are made to face each other; the first cylindrical body 30 is rotatably fixed to the second cylindrical body 35. A shower water drain tool 4 comprises a third cylindrical body 40 on which an accommodation hole 43 is provided and accommodates a drain valve 45 for closing a drain hole 47 when water supply pressure is applied to the accommodation hole 43 and opening a drain hole 47 when the water supply pressure is released. The second cylindrical body 35 and third cylindrical body 40 are unified or connected by detachable fixation means.SELECTED DRAWING: Figure 2 【課題】シャワー使用時に湯水の節水をはかり，シャワー終了時にシャワーヘッドに残留する湯水を自動的に外部へ排出させるシャワー設備用節水装置を提供すること。【解決手段】節水具２は，第１の通水孔が設けられた第１の筒状体３０と，内部が中空な第２の筒状体３５と，第１の通水孔の開口を所定の範囲で閉口又は開口して通水する第２の通水孔を有する節水板３８とを備え，この節水板３８と第１の筒状体３０の閉鎖壁３１面とを対峙させて第１の筒状体３０を前記第２の筒状体３５に対して回転自在に固定している。シャワー排水具４は，収容孔４３を設けた第３の筒状体４０を備え，収容孔４３に給水圧が掛かると水抜き口４７を閉塞し，給水圧が解除されるとドレイン孔４７を開放する水抜き弁４５が収容されており，第２の筒状体３５と第３の筒状体４０とは一体又は着脱自在な固定手段により結合されている。【選択図】 図２
