Claims

[Scope of utility model registration request]

In a rotating window in which a movable window frame is rotatably fitted in a fixed window frame fixed to a building frame via a bearing device, the bearing device includes a fixed bearing block fixed to the fixed window frame, and a movable window frame fixed to the fixed window frame. It has a movable bearing block fixed to the window frame, and a support shaft for rotating the movable window frame arranged between both blocks, and a square shaft shaped concentrically with the support shaft is provided on one of the opposing surfaces of the blocks. A locking portion is integrally formed, and a rotation restriction ring having a rotation restriction concave portion formed on the outer circumferential surface of the square shaft locking portion is non-rotatably and removably fitted into the square shaft-shaped locking portion. A stopper pin that fits into the recess is provided protrudingly, and the rotation restriction ring is configured to change the fitting position in the circumferential direction with respect to the square shaft-shaped locking part, so that the rotation restriction recess formed on the outer periphery of the ring is changed. A rotating window bearing device configured to be able to be changed to a desired direction.
