To provide a drive device capable of avoiding an occurrence of a slack in a lifting cord of an intermediate rail.SOLUTION: Provided is a drive device having first and second drive shafts 11, 12 and a clutch device 38. The clutch device has a clutch 41 and first and second movement members 39, 40. The clutch does not transfer the rotation of the second drive shaft to the first drive shaft in a non-coupling state, and transfers the rotation of the second drive shaft to the first drive shaft in a coupling state. The first and second movement members move along a shaft center of the first and second drive shafts with the rotation of the first and second drive shafts, respectively. When the second movement member is moved with the rotation of the second drive shaft to press the first movement member and the first movement member is moved slidably in one direction along the shaft center of the first drive shaft in the non-coupling state, the clutch is moved slidably with the sliding movement into the coupling state.SELECTED DRAWING: Figure 5
【課題】中間レールの昇降コードに弛みが発生することを避けることが可能な駆動装置を提供する。【解決手段】第１及び第２駆動軸１１、１２と、クラッチ装置３８を備える駆動装置であって、前記クラッチ装置は、クラッチ４１と、第１及び第２移動部材３９、４０を備え、前記クラッチは、非連結状態では第２駆動軸の回転を第１駆動軸に伝達させず、連結状態では第２駆動軸の回転を第１駆動軸に伝達し、第１及び第２移動部材は、それぞれ、第１及び第２駆動軸の回転に伴って第１及び第２駆動軸の軸心に沿って移動し、前記非連結状態において、第２駆動軸の回転に伴って第２移動部材を移動させて第１移動部材を押圧して第１移動部材を第１駆動軸の軸心に沿った一方向にスライド移動させると、このスライド移動に伴って前記クラッチがスライド移動して前記連結状態となる、駆動装置が提供される。【選択図】図５
