This window opening / closing device rotates the screw shaft in conjunction with the drive shaft when the drive shaft is rotated by the handle of the drive box or the motor drive via the transmission mechanism during normal ventilation, and the screw shaft is screwed. The moving block members that are fitted together move up and down according to the direction of rotation to open and close the window at an arbitrary position via the protruding arm.On the other hand, in the event of a fire or other emergency, the lock release mechanism activates the lock. When the locking of the slide member by the lever is released, the slide member is pulled up by the force of the opening spring, and at this time, the screw shaft and the moving block member provided on the sliding member are also pulled up together, so one end is connected to the moving block. The window is instantly opened via the protruding arm.
