Abstract
This apparatus comprises, in combination, two similar devices disposed in opposite directions. The devices are adapted to be fixed respectively to the two opposite wheels of a vehicle and parallel to the latter. Each device comprises a first rigid hollow tubular bar and a fixing structure for fixing the bar to a projector carrier. A structure inside the bar projects a beam of light longitudinally inside the bar. The beam is reflected at one end of the bar by a mirror which is rigid with a screen and so disposed as to project the beam transversely toward the screen pertaining to the opposite device. The mirror is mounted on the first bar of at least one of the devices so as to be movable toward or away from the fixing structure. A structure for receiving a sub-assembly for inspecting the pivot and castor angles of the vehicle wheel is provided. An apparatus for measuring the camber angle of the vehicle wheel is also provided.
