WASHING DEVICE

PROBLEM TO BE SOLVED: To provide a washing device in which packing provided in a pressing manner between a holder screwed and attached to a lead-through end part of a conduit and a peripheral wall of a washing tank opposing thereto can reliably exhibit a seal performance.SOLUTION: A washing device 10 comprises: a washing tank 20 having a water storage part 21 for storing washing water at a bottom part thereof; washing nozzles 24, 25 for injecting the washing water; a washing pump 26 for feeding the washing water into the washing nozzles 24, 25; a conduit 30 inserted into the washing tank 20 through through-holes 20a, 20b that are formed by lead-through end parts 31b, 33b at a peripheral wall of the washing tank 20 and that guide the washing water fed from the washing pump 26 to the washing nozzles 24, 25; a holder 41 screwed and attached to the lead-through end parts 31b, 33b of the conduit 30 and rotatably supporting the washing nozzles 24, 25; and packing 42 provided in a pressing manner between the holder 41 and the peripheral wall of the washing tank 20 opposing thereto. A cylindrical member 43 for limiting a crush allowance of the packing 42 is provided between the holder 41 and the peripheral wall of the washing tank 20 opposing thereto. 【課題】導管の導出端部に螺合して取り付けたホルダとこれに対向する洗浄槽の周壁との間に押圧して設けたパッキンが確実にシール性能を発揮できるようにする。【解決手段】洗浄装置１０は、洗浄水を貯える貯水部２１を底部に有した洗浄槽２０と、洗浄水を噴出する洗浄ノズル２４，２５と、洗浄水を洗浄ノズル２４，２５に送り出す洗浄ポンプ２６と、その導出端部３１ｂ，３３ｂが洗浄槽２０の周壁に形成した貫通孔２０ａ、２０ｂから洗浄槽２０内に挿通され、洗浄ポンプ２６から送出される洗浄水を洗浄ノズル２４，２５に導く導管３０と、導管３０の導出端部３１ｂ，３３ｂに螺合して取り付けられて洗浄ノズル２４，２５を回転可能に支持するホルダ４１と、ホルダ４１とこれに対向する洗浄槽２０の周壁との間に押圧して設けられたパッキン４２とを備え、ホルダ４１とこれに対向する洗浄槽２０の周壁との間にはパッキン４２のつぶし代を制限する筒形部材４３を設けた。【選択図】図３
