Claims

[Scope of utility model registration request]

An elongated drum having a single spiral groove formed on its outer circumferential surface, which serves as a rope winding groove, is rotatably supported in a case, and the rope introduced into the drum in the axial direction of the drum is directed toward the spiral groove. A movable body pivotally supporting a pulley that rotates in a direction substantially perpendicular to the axial direction of the drum is screwed together, and a fitting portion formed on the movable body is provided in the case for guiding along the axial direction of the drum. one end of the rope is fixed to one end of the drum;
Rotation of the drum in one direction moves the moving body in one direction along the drum while winding the rope in the spiral groove, and rotation of the drum in the opposite direction moves the moving body in the opposite direction. a rope winding device configured to let out the rope from the spiral groove while winding the rope; and a motor driving the drum of the rope winding device in the rope winding direction.
The rope is fixed to the building side through a non-reversible clutch that cuts off the transmission of rotational force from the drum side to the motor side, or the motor is connected to the building so that it can idle when not energized, and the rope is fixed to the building side. Alternatively, a locking device is provided which is connected to the window plate biased in the window opening direction by a spring force, always prevents rotation of the drum in the rope payout direction, and releases the rotation prevention by external operation. A window opening/closing device featuring:
