POWER TRANSMISSION DEVICE AND SHADING DEVICE
To provide a power transmission device and a shading device that enable improved responsiveness in preventing a shading member from falling under its own weight.SOLUTION: The power transmission device comprises: a connecting member 35 that is rotated by input from an operating part; an output member 52 to which a drive shaft 12 is connected and which is disposed in the direction of the extension of a connecting part 35b; and a drum 53 which rotates in unison with the connecting member 35 and which can be selectively switched between a connected state and a disconnected state for connection to and disconnection from the output member 52 when moving in the direction of the rotation axis. The drum 53 is provided with a guide groove 61 that continues in the circumferential direction on the outer circumferential surface, and balls 55a and 55b that engage the guide grooves 61 between the drum 53 and the cover 54 that covers the drum 53. The guiding groove 61 has a first switching groove section that moves the drum 53 from the connected state to the disconnected state, a disconnection groove section that maintains the drum in the disconnected state, a second switching groove section that moves the drum from the disconnected state to the connected state, and a plurality of pocket sections that prevent the drum 53 from rotating in the direction of the descent of a shading member in the connected state.SELECTED DRAWING: Figure 12
【課題】遮蔽材の自重降下を阻止する際の応答性の向上を可能とした動力伝達装置および遮蔽装置を提供する。【解決手段】操作部からの入力によって回転される接続部材３５と、駆動軸１２が接続され、接続部３５ｂの延長方向に配置される出力部材５２と、接続部材３５と一体的に回転するドラム５３であって、回転軸線方向に移動することで、選択的に出力部材５２に対して接続された接続状態と切り離された切離状態とに切り替えられるドラム５３とを備える。ドラム５３は、外周面に周回方向に連続する案内溝６１を備え、ドラム５３を覆うカバー５４との間には、案内溝６１に係合するボール５５ａ，５５ｂを備える。案内溝６１は、ドラム５３を接続状態から切離状態に移動する第１切替溝部と、切離状態に維持する切離溝部と、切離状態から接続状態に移動する第２切替溝部と、接続状態でドラム５３の遮蔽材の降下方向の回転を阻止する複数のポケット部とを備える。【選択図】図１２
