Abstract
Abstract A device for cleaning the headlamp glass of an automobile headlamp. The device is formed in two main units, a motor unit and a reduction gear unit, which latter carries a wiper blade which, in use of the device, is moved over the surface of the glass to effect cleaning. The motor is mounted inside the headlamp and the gear unit outside, the two being connected together through a hole in the headlamp glass. A resilient seal is provided to make the joint waterproof and there are various arrangements for ensuring that the assembly is correctly centred within the hole in the glass and oriented properly in an angular sense.
