PROBLEM TO BE SOLVED: To provide a shielding material lifting device capable of restraining a bottom rail from descending by dead weight before completing tilt operation.SOLUTION: The present invention provides a shielding material lifting device for lifting a shielding material by rotating a lifting shaft by operation of an operation cord, and the shielding material lifting device is provided with a clutch unit having an input shaft for rotating in response to the operation of the operation cord and an output shaft for integrally rotating with the lifting shaft, in which the clutch unit comprises a cam part for moving a camshaft in its axial direction in response to rotation of the camshaft for rotating in response to rotation of the input shaft and a clutch part for switching a connected-unconnected state between the camshaft and the output shaft in response to the movement of the camshaft, and has 90 degrees or more in a rotation angle in the descent direction of the camshaft required when switching to the unconnected state from the connected state.SELECTED DRAWING: Figure 8
【課題】チルト操作の完了前にボトムレールが自重降下することを抑制することができる、遮蔽材昇降装置を提供する。【解決手段】本発明によれば、操作コードの操作によって昇降軸を回転させて遮蔽材を昇降させる遮蔽材昇降装置であって、前記操作コードの操作に伴って回転する入力軸と、前記昇降軸と一体回転する出力軸と有するクラッチユニットを備え、前記クラッチユニットは、前記入力軸の回転に従って回転するカム軸の回転に伴って前記カム軸をその軸方向に移動させるカム部と、前記カム軸の移動に伴って前記カム軸と前記出力軸の間の連結・非連結状態を切り替えるクラッチ部を備え、前記連結状態から前記非連結状態に切り替える際に必要な前記カム軸の降下方向の回転角度は９０度以上である、遮蔽材昇降装置が提供される。【選択図】図８
