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 fixed to the arms. The pivot members define a chamber in which an axially movable member is positioned. One of the pivot members has axially extending circumferentially spaced grooves therein and a movable member has complementary projections. The movable member is yieldingly urged toward the member having the grooves such that the mirror is held in angularly adjusted position but may be readily moved to a new angular position by manual manipulation.
