FIELD: motor vehicle repairing operations. SUBSTANCE: apparatus has a frame, supporting a driven mandrel for a wheel to be straightened and a straightening mechanism, being in the form of a central shaping roller, mounted in bearing units, and two lateral straightening rollers, mounted by a cantilever fashion on rotary levers, joined by a cross piece. The bearing unit of the straightening mechanism is in the form of fork-like lever, whose one axle is secured to the frame with possibility of slight rocking, and whose other axle carries the central shaping roller. The lateral rotary levers have through lengthwise slots for motion of the axle of the central roller. The lateral rollers have a manual drive unit in the form of a leading screw, connected by a threaded joint with the cross piece, being freely mounted on its support. A rocker arm, resting upon a lateral surface of the fork-like lever, and a handle for rotating the leading screw are mounted on the leading screw. A rim of the wheel, being rotated, rolls between the central and the lateral rollers, being forced one to another with an effort, and in the result the rim is being straightened. EFFECT: enhanced serviceability of the apparatus. 1 cl, 3 dwg
