Abstract

Apparatus for checking the parallelism of the front or rear wheels 2a,2b of a vehicle, comprises two arms 1a,1b intended to be fixed horizontally against the external faces of the two wheels to be checked and means for ascertaining the parallelism of these wheels. At the extremity 5 of each horizontal arm opposite to that intended to be fixed against a wheel, there is provided a pivoting element 6a, 6b adapted to project or reflect a light beam in the direction of the corresponding extremity of the other arm, and a checking sighting mark intended to receive the light spot coming from the projection or reflection element provided on the other arm of this apparatus. The rotation of each projection or reflection element is controlled by a graduated drum 14 the scale zero of which is opposite to a fixed index when the light beam coming from the reflection element is oriented at right angles to the corresponding arm of this equipment.
