To provide a door driving device which can be miniaturized.SOLUTION: A door driving device includes: a base member 11 extending in the opening width direction of a door; a rotary moving body 32 pressed against the base member 11 and moved while rotating along the base member 11; a rotary shaft 13 extending in the opening width direction of the door and rotated by power of a motor; and a transmission member 31. The transmission member 31 is movable relative to the axial direction of the rotary shaft 13, rotates together with the rotary shaft 13, and contacts with the rotary moving body 32 for transmitting the rotational force of the rotary shaft to the rotary moving body 32.SELECTED DRAWING: Figure 5
【課題】小型化が可能なドア駆動装置を提供する。【解決手段】ドア駆動装置は、ドアの開口幅方向に延びるベース部材11と、ベース部材11に押し当てられベース部材11に沿って回転しながら移動する回転移動体32と、ドアの開口幅方向に延びてモーターの動力で回転する回転軸13と、伝達部材31とを備える。伝達部材31は、回転軸13の軸方向に対して相対移動可能であり、かつ、回転軸13と共に回転し、回転移動体32と接触することによって回転軸の回転力を回転移動体32に伝達する。【選択図】図5
