To provide a powder coating apparatus capable of restraining the surface height fluctuation of a fluidized bed.SOLUTION: There is provided a powder coating apparatus 1 by a fluidization immersion method including coating a workpiece by immersing in a fluidized bed in which a powder coating material is fluidized. The apparatus comprises: a fluid container 2 capable of storing the powder coating material; an inner cylinder 6 provided in the fluid container 2 and having an opening capable of inserting the portion of the workpiece to be coated; and a fluidization generating means 5 generating an air current from the lower part of the inner cylinder 6 toward the upper part thereof to form the fluidized bed of the powder coating material inside the inner cylinder 6. The apparatus is configured to overflow the powder coating material from the upper end of the inner cylinder 6.SELECTED DRAWING: Figure 1 【課題】流動層の表面高さの変動を抑制することのできる粉体塗装装置を提供する。【解決手段】粉体塗料を流動させた流動層にワークを浸漬させて塗装する流動浸漬法の粉体塗装装置１であって、粉体塗料を収容可能な流動容器２と、流動容器２内に設けられ、ワークの塗装する部分を挿入可能な開口を上部に有する内筒６と、内筒６の下部から上部に向かう気流を生じさせて内筒６の内側で粉体塗料の流動層を形成させる流動発生手段５と、を備え、内筒６の上端から粉体塗料を溢れさせる。【選択図】図１
