PROBLEM TO BE SOLVED: To provide a sterilization device for a passenger conveyor handrail that applies sterilization effect by a photocatalyst to the handrail, and besides can suppress deterioration in the handrail caused by action of the photocatalyst.SOLUTION: The sterilization device for a passenger conveyor handrail is provided for sterilizing an endless handrail which moves in an orbiting manner in synchronization with a step of a passenger conveyor. The sterilization device comprises: slurry application means that adheres slurry liquid containing water and/or aqueous media and photocatalyst particles dispersed in the water and/or the aqueous media to a surface of the handrail; photocatalyst excitation means that comprises at least one ultraviolet light emitting diode which emits ultraviolet light with a wavelength at which photocatalyst is excited, and that excites photocatalyst by irradiating the surface of the handrail to which the slurry liquid is adhered with ultraviolet light emitted from the ultraviolet light emitting diode; and slurry removing means that removes the slurry liquid from the irradiated surface of the handrail having passed through the photocatalyst exciting means.SELECTED DRAWING: Figure 4
【課題】光触媒による殺菌作用をハンドレールに適用しながらも、光触媒の作用によるハンドレールの劣化を抑制することが可能な、乗客コンベアのハンドレール殺菌装置を提供する。【解決手段】乗客コンベアのステップと同期して周回移動する無端状のハンドレールを殺菌するための装置であって、水および/または水性媒体並びに該水および/または水性媒体中に分散した光触媒粒子を含むスラリー液をハンドレールの表面に付着させるスラリー塗布手段と、光触媒を励起する波長の紫外線を発光する紫外発光ダイオードを1つ以上備え、スラリー液が付着したハンドレールの表面に紫外発光ダイオードから発せられる紫外光を照射することにより光触媒を励起させる光触媒励起手段と、光触媒励起手段を経たハンドレールの表面からスラリー液を除去するスラリー除去手段とを有する、乗客コンベアのハンドレール殺菌装置。【選択図】図4
