Abstract
This specification discloses a vehicular mirror assembly adapted for exterior use on vehicles and is corrosion resistant, has low vibration, resists unintentional adjustment and may be adjusted when desired to a full range of positions. A mirror head housing is attached to a vehicular body housing by a support shaft pivotally secured to each housing by a pivot assembly. Each pivot assembly includes two coacting journal bearing members with a frictional member therebetween to provide a constant biasing force continuously over the life of the assembly which resists rotation of the shaft with respect to the housings. In the preferred embodiment, one of the journal bearing members is a serpentine spring.
