Abstract
A window opener composed of a motor retained in a casing, a damper for vibration isolation suitable interposed between the motor and the casing, a worm and a worm wheel which are concentrically connected to an output shaft of the motor, and pinion which is concentrically projected from the worm wheel, an output gear engaged with the pinion, a shaft projected from an upper surface of the output gear and a link mechanism for transforming a rotational force in one direction of the shaft into an opening force and transforming the rotational force in another direction of the shaft into a closing force of the window; being characterized in that the worm and worm wheel and the output gear are arranged in such a manner as to be superposed.
