PROBLEM TO BE SOLVED: To provide a mist bath apparatus that can be maintained easily.SOLUTION: A casing 1 set to an attic 80 is provided with a front-surface wall 11 facing to the front F, and a one side wall 12 adjacent to the front-surface wall 11. A joint part 5 to which an outer water-supply pipe is connected, is set to an inner water-supply pipe so as to be attachable to or detachable from a connecting part at the front-side edge part as the upstream edge of the inner water-supply pipe 2. A filter part 60 projecting to the side of one side wall 12 is set to the rear side of the connecting part. A part to which the joint part 5 and the filter part 60 of the inside water-supply pipe 2 are set, and the connecting part are formed to be movable back and forth. A front face hole 13 through which the upstream edge of the inner water-supply pipe 2 can be passed, is formed at the front-surface wall 11. A side-wall hole 14 through which the filter part 60 can be passed, is formed at the one side wall 12. The front-back width of the side-wall hole 14 is made long so that the filter part 60 is movable inside the side-wall hole 14 when moving the connecting part from the back of the front-surface wall 11 to the front of the front-surface wall 11.COPYRIGHT: (C)2014,JPO&INPIT【課題】メンテナンスが容易に行えるミスト浴装置を提供する。【解決手段】天井80裏に設置されるケーシング1は、前方Fを向く正面壁11と、正面壁11に隣接する一側壁12と、を備える。内部給水管2には、外部給水管が接続される継手部5が、内部給水管2の上流端となる前方側の端部の結合部に着脱自在に設けられ、前記結合部の後方側に一側壁12側に突出するフィルタ部60が設けられ、内部給水管2の継手部5およびフィルタ部60が設けられた部分および前記結合部が前後に移動可能に形成される。正面壁11に内部給水管2の上流端が挿通可能な正面孔13が形成されるとともに、一側壁12にフィルタ部60が挿通可能な側壁孔14が形成され、側壁孔14の前後幅は、前記結合部を前記正面壁11の後方から前記正面壁11の前方に移動させたときに前記フィルタ部60が前記側壁孔14の中を移動可能な長寸に形成される。【選択図】図5
