摘要：
PROBLEM TO BE SOLVED: To provide a pulse shower device which can secure the smooth rotation motion of an impeller and has excellent durability.SOLUTION: A pulse shower device 45 comprises a spray plate 62 having a plurality of shower holes 64 which penetrate the external face from the internal face, and an impeller 72 which is arranged at the upstream side of the spray plate 62, and rotationally moves around a shaft by making a water flow abut on blades 108. The pulse shower device intermittently discharges shower water in a pulse state from the shower holes 64 by the rotation of the impeller 72. A protrusion 124 protruding toward the impeller 72 side is formed at the spray plate 62, and an apex of the protrusion 124 is made to serve as an abutment part 126 which abuts on a supported face 130 at the spray plate 62 side of the impeller 72 opposing the apex at the rotation center, and supports the impeller 72.COPYRIGHT: (C)2014,JPO&INPIT【課題】羽根車の円滑な回転運動を確保でき、また優れた耐久性を有するパルスシャワー装置を提供する。【解決手段】内面から外面に貫通した複数のシャワー孔64を備えた散水板62と、散水板62の上流側に設けられ、水流を羽根108に当てることで軸周りに回転運動する羽根車72と、を備え、羽根車72の回転によりシャワー孔64からシャワー水をパルス状に断続吐水するパルスシャワー装置45において、散水板62には、羽根車72側に突出する突起124を設けて、突起124の頂部を、頂部に対向する羽根車72の散水板62側の被支持面130に回転中心で当接し羽根車72を支持する当接部126と成す。【選択図】 図3
