PROBLEM TO BE SOLVED: To provide a powder and granular material spraying device capable of easily preventing clogging with powder and granular material in a diffusion guide case, and capable of easily preventing occurrence of trouble caused by a clogging prevention means.SOLUTION: The powder and granular material spraying device includes a rotator 50 which includes a rotary plate 51 for receiving powder and granular material and blades 52 projecting upward from the rotary plate 51 for sputtering powder and granular material. The diffusion guide case 58 includes: a ceiling wall part 58A a vertical wall part 58B located along the outer peripheral edge of the rotator 50 on the opposite side from where a diffusion port 58C to the rotator 50 is located and a guide lateral wall part 60 located between the diffusion port 58C and the vertical wall part 58B for guiding diffusion of the powder and granular material. The diffusion guide case 58 is opened downward. The lower ends 58Bt and 60t of the vertical wall part 58B and the guide lateral wall part 60 are lower than the lower end 50t of the rotator 50.COPYRIGHT: (C)2012,JPO&INPIT【課題】拡散ガイドケースにおける粉粒体詰まりを回避しやすく、かつ詰まり回避の手段に起因する問題発生も回避しやすい粉粒体散布装置を提供する。【解決手段】回転体50を、粉粒体を受け止める回転板51と、回転板51から上方向きに突出して粉粒体を跳ね飛ばす羽根体52とを備えて構成してある。拡散ガイドケース58を、天井壁部58Aと、回転体50に対して散布口58Cが位置する側とは反対側に回転体50の外周縁に沿って位置して粉粒体の飛散を規制する縦壁部58Bと、散布口58Cと縦壁部58Bとの間に位置して粉粒体を拡散案内する案内横壁部60とを備えて構成し、拡散ガイドケース58が下向きに開口するようにしてある。縦壁部58B及び案内横壁部60の下端58Bt,60tを、回転体50の下端50tより低くしてある【選択図】図4
