Claims (1)

[Scope of utility model registration request] Inside a window frame consisting of upper and lower horizontal frames and left and right vertical frames, a window shoji is surrounded on all sides by the upper and lower horizontal frames and left and right vertical frames, and is rotatable about the vertical axis. A device for adjusting the opening degree of a built-in window,
The length of this connecting arm is attached to the distal end of the connecting arm whose base end is pivotally attached to one of the horizontal frames and whose rotation amount is limited so that it can rotate only between the closed state and the half-opened state of the window sash. An engagement groove is formed that includes a straight body part extending in the horizontal direction and a continuous slope part bent from the straight body part, and the slope part connects the straight body part and the outside of the connecting arm with each other, and When the window shoji is in a half-open state, it will be parallel to the horizontal frame, and depending on the amount of operation of the handle for opening and closing the window, the base end of the connecting arm will be opposed to the horizontal frame which is pivoted. A window opening adjustment device in which a pin provided at the tip of a horizontally moving member that moves horizontally along a horizontal stile can be freely engaged with the engagement groove.
