Claims

[Scope of utility model registration request]

A window plate is hinged to either the upper edge or the lower edge of a window frame fixed at a high place in a building, and the hinged edge of the window plate of the window frame is biased in the direction of window opening by spring elasticity. A drum having an axis parallel to the edge as its axis is freely supported on the edge corresponding to the edge, and the extending end of the flexible strip wound around the drum is connected to the swinging end of the window plate. A rotating wheel for rotationally driving the drum and a locking mechanism for locking the drum so that it cannot rotate when the rotating wheel is stopped are installed in the window frame, and an operating rod wound around the rotating wheel is suspended to an operating position. A swinging type high window opening/closing device characterized by:
