PURPOSE: A jig of a vehicle wheel is provided to fix the vehicle wheel by combining the separable jig of the vehicle wheel between a protrusion shaft of the vehicle wheel and a rim. CONSTITUTION: A jig of a vehicle wheel(19) has a fixed jig member(10), a length adjusting device and a fixed member(30). The fixed jig member is fixed to a protrusion shaft(12) of the vehicle wheel. The length adjusting device is combined to a side of the fixed jig member to be adjusted. The fixed member is fixed to a side of the length adjusting member as a circular contacting an inner rim of the wheel. The fixed jig member has protrusion portions(13) on both ends. A jig body is fixed to the protrusion shaft by screwing a bolt member(11). A protrusion combining portion(17) which has a thread on an outer peripheral surface is formed to a lower portion of the jig body to be combined with the length adjusting device. A pad member(31) is combined to the fixed member to support the fixed member to the rim. Therefore, a vehicle is prevented from moving in a wind tunnel test by preventing the vehicle body from rotating with the jig.
