Abstract
A drive apparatus for opening and closing a window glass provided in a door having an inner panel is disclosed. The drive apparatus includes a motor provided in the door and a regulator that receives drive force from the motor and selectively open and close the window glass. The door noise includes motor operating noise and vibration transmission noise that is generated when vibration of the motor is transmitted to the inner panel via the regulator. The motor is configured such that a first-order frequency component in vibration of the motor is greater than any other nth component (n is an integer greater than or equal to two), so that the first-order frequency component in the door noise is greater than any other nth frequency component (n is an integer greater than or equal to two).
