To prevent or suppress a gas from being blown through while increasing the cross-sectional area of a carrying space.SOLUTION: A powder carrier device comprises: a rotary cylindrical part 21 which is in a cylindrical shape extending along a predetermined axis of rotation J1, and rotates on the axis of rotation and also allows a gas to flow inside; an inner cylinder part 51 which has a cylindrical inner cylinder body 511 extending in an axial direction parallel with the axis of rotation, the inner cylinder body rotating inside the rotary cylindrical part together with the rotary cylindrical part in one body; an outer carrying structure 53 which carries powder along the axial direction inside a cylindrical outer carrying space 530, provided between an outer peripheral surface of the inner cylinder body and an inner peripheral surface of the rotary cylindrical part, as the rotary cylindrical part rotates; and an inner carrying structure 52 which carries the powder along the axial direction inside an inner carrying space 520, provided inside the inner cylinder body, as the rotary cylindrical part rotates. The outer carrying structure comprises a guide plate 532 which extends spirally in the axial direction while connecting the outer peripheral surface of the inner cylinder body and the inner peripheral surface of the rotary cylindrical part.SELECTED DRAWING: Figure 1 【課題】搬送空間の断面積を大きくしつつ、ガスの吹き抜けを防止または抑制する。【解決手段】粉体搬送装置は、所定の回転軸Ｊ１に沿って延びる筒状であり、回転軸を中心として回転するとともに内部にガスが流れる回転筒状部２１と、回転軸に平行な軸方向に延びる筒状の内筒本体５１１を有し、内筒本体が回転筒状部の内部において回転筒状部と一体的に回転する内筒部５１と、内筒本体の外周面と回転筒状部の内周面との間に設けられる筒状の外側搬送空間５３０において、回転筒状部の回転に伴って粉体を軸方向に搬送する外側搬送構造５３と、内筒本体の内部に設けられる内側搬送空間５２０において、回転筒状部の回転に伴って粉体を軸方向に搬送する内側搬送構造５２とを備える。外側搬送構造が、内筒本体の外周面と回転筒状部の内周面とを接続しつつ軸方向に螺旋状に延びるガイド板５３２を備える。【選択図】図１
