The invention relates to a ventilation device for balancing air pressure inside and outside a motor vehicle. The ventilation device comprises a mounting frame and a valve plate. The mounting frame comprises a main frame body and secondary frame bodies. The main frame body comprises a mounting through hole. Each secondary frame body comprises a frame, a ventilation hole and an inserting hole. The included angle between the center axis of the mounting through hole and the center axis of the ventilation hole comprises an acute angle. When the ventilation device is used, the arrangement directionof the multiple secondary frame bodies is parallel to the vertical direction, and the inserting hole of each secondary frame body is located in the upper side of the secondary frame body in the vertical direction. The valve plate is made of a flexible material, covers the ventilation holes and comprises an inserting handle. The inserting handle comprises a connecting portion and clamping portions.The connecting portion penetrates through the inserting holes, and the two clamping portions are clamped on the two axial outer side walls of the inserting holes. According to the ventilation device,noises from the outside of the vehicle can be reduced as much as possible, and the vehicle using experience of a user is improved.
