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.

An apparatus for inspecting the geometry of wheels of a vehicle, comprising, in combination, two measuring devices adapted to be fixed respectively to two front wheels of the vehicle and which, in use, have a generally symmetrical shape with respect to each other, each of said devices comprising in combination a first hollow tubular rigid bar, a projector carrier adapted to be mounted on one of said front wheels, means for fixing the bar to the projector carrier whereby said bar extends substantially parallel to said wheel, means inside the bar for projecting a beam of light longitudinally of the bar, a unit disposed at one of the bar and comprising a screen, a mirror rigid with the screen and disposed in such manner as to reflect said beam and project said beam transversally of the apparatus toward the screen pertaining to the opposite device of said two devices, said apparatus further comprising, on at least one of said devices, a second tubular bar having one end portion telescopically and slidably mounted in said first bar so that the second bar is movable toward and away from said fixing means, a locking means for arresting telescopic movement of said second bar in said first bar, said unit comprising the mirror and the screen being mounted on the second bar adjacent an end of the second bar opposed to said one end portion, whereby relative telescopic movement of said first and second bars allows for compensation of set-back of the rear wheels of said vehicle, the apparatus further comprising means on each of said devices for receiving a sub-assembly for inspecting the kingpin inclination and the castor angle of the vehicle wheels.
