Windshield wiper device

The invention relates to a pressure compensation device for compensating pressure between an inner chamber of a housing, in particular an electric motor, gearbox, container or the like and an outer side. The device includes a pressure compensation membrane mounted on an annular end face of a cylindrical structure that extends toward the outer side. The cylindrical structure is provided with a ventilation channel that extends therethrough. The cylindrical structure extends towards the outer side in order to form a projection from the wall of the housing, which projection is delimited by the end face on which the membrane is applied in a curved, dome-shaped form. A protective cover extends towards the outer side at a spaced apart distance in relation to the membrane over the cylindrical structure.
