Abstract
A bearing apparatus for pivotally moving a carrying arm relative to an anchorage is provided. The carrying arm may carry a mirror for a vehicle, the anchorage mountable to the vehicle. The bearing apparatus has a bushing located between the carrying arm and the anchorage in which a pivot bearing apparatus is moveably disposed. In one embodiment the pivot bearing apparatus has a control component and a come-along part relationally disposed about a shaft and movably connected to the control component. When the shaft is rotated, the come-along part moves along the shaft to rotate the control component. In turn, the control component transfers its rotation to pivot the carrying arm.
