An eccentric shaft 17 is fixed to the worm wheel, and one end of a swinging plate 18 having an arcuate pressure contact surface 18a is pivotally mounted in the main body 1 so as to be swingable in the radial direction of the worm wheel. A plate spring 20 is attached, and the plate spring elastically biases the swinging end side of the swing plate, thereby pressing the swing plate against the eccentric shaft, and causing the worm wheel to move in the direction in which the louver closes. A louver window opening/closing device characterized in that the louver window opening/closing device is configured so that the rotational torque gradually increases when rotating.
