Abstract
Abstract A rear view mirror for a motor vehicle of the kind having a stationary housing relative to which the reflective element is adjustable to give the required rear view has a housing which is moulded in self-skinning foam plastics. The housing has resilient pillars which bear on the back of the reflective element near its periphery. The pillars extend from the part of the housing behind the reflective element. Vibration of the reflective element is damped by contact with the resilient material of the housing and the reflective element is kept in its adjusted position. This is very useful when the reflective element is adjustable by remote control.
