Abstract
Abstract A truck mirror comprising a U-shaped support on which a mirror is pivotally mounted. The ends of arms of the support are pivoted to vertically spaced brackets that are adapted to be mounted on the truck. Pivot means are provided between the ends of the support arms and the brackets and comprise two members of low friction material. One of the members has axially extending circumferentially spaced grooves therein and the other of the members has complementary projections. The members are yieldingly urged toward one another such that the mirror is held in angularly adjusted position but may be readily moved to a new angular position by manual manipulation.
