PROBLEM TO BE SOLVED: To provide a movable body moving device which can enhance a degree of freedom in a size and arrangement of a sprocket and an engagement chain while suppressing the enlargement of the device.SOLUTION: A movable body moving device comprises: an engagement chain 14 in which chain members 41, 42 are engaged and integrated with each other by moving to one direction, and branched from each other by being released in the engagement due to the movement of the chain members 41, 42 to the other direction from the integrated engaged state; a drive sprocket 31 which is engaged with the first chain member 41, and moves the engagement chain 14 to an advanceable and contractible direction; and a movable body which moves so as to be advanceable and contractible together with the engagement chain 14. The first chain member 41 has a plurality of gearing parts 51, 52 which are geared with the drive sprocket 31, and a non-gearing part 41a which is released in the gearing from the drive sprocket 31. The non-gearing part 41a is a portion which is continuous between the gearing parts 51, 52 in a longitudinal direction of the chain member 41.SELECTED DRAWING: Figure 3
【課題】装置の大型化を抑制しつつ、スプロケットや噛合チェーンの、サイズや配置の自由度を高めることができる可動体移動装置を提供する。【解決手段】チェーン部材41,42同士が一方向に移動することで相互に噛み合って一体化する一方、その一体化した噛合状態からチェーン部材41,42同士が他方向に移動することで相互に噛み外れて分岐する噛合チェーン14と、第1チェーン部材41と歯合して噛合チェーン14を進退移動方向へ移動させる駆動スプロケット31と、噛合チェーン14と共に進退移動する可動体とを備え、第1チェーン部材41は、駆動スプロケット31と歯合する複数の歯合部51,52と、駆動スプロケット31から噛み外れた非歯合部41aとを有し、非歯合部41aは、チェーン部材41の長手方向において歯合部51,52間で連続した部分である。【選択図】図3
