PROBLEM TO BE SOLVED: To provide an auxiliary apparatus for the test of a vehicle which is suitable e.g. for the test of a speedometer at a large vehicle, in which a riding-into plate is connected to a base frame so as to be foldable and detachable, which is moved easily, whose storage is made compact, which deals with the large size and the large weight of this kind of apparatus, which complies easily and rationally with the replacement of a main component and which can deal with slight irregularities on an installation face and a test condition. SOLUTION: The base frame 7 by which a plurality of rollers 6 used to place wheels 32 are supported so as to be freely rotatable is installed. Riding- into plates 8 on which the wheels 32 can ride into are attached to opposite frame bodies 10, 10 at the base frame 7. The opposite frame bodies 10, 10 at the base plate 7 are connected in such a way that the riding-into plates 8 can be turned in the up-and-down direction.
