PURPOSE:To improve the operationability of a window by combining a drive mechanism opening and closing the window and a latch mechanism by a control cable and driving a latch as being interlocked with the opening and closing of the window while manually opening the window at the time of emergency. CONSTITUTION:A drive mechanism 4 by a motor opening and closing a window board 2 and a latch mechanism 5 constraining the opening of the window board 2 are coupled by a control cable 6. A grooved cam 28 having a play region is installed to the window board 2, and connected to the drive mechanism 4 through a driving lever 23. A knob for manual operation disengaging engagement with a lock arm is mounted previously on a drive 4. When the window 2 is opened and closed, the latch 5 is released and constrained when the motor 4 is driven and the driving lever 23 is positioned in the play region of the grooved cam 28. The window is opened and closed by manual operation at the time of emergency. Accordingly, the operationability of the opening and closing of the window can be improved. |
