PROBLEM TO BE SOLVED: To accurately measure a tire posture angle of a running vehicle. SOLUTION: A time posture angle measuring jig 10 includes a first plate 22 to be attached to a wheel, a second plate 24, and a third plate 26 having a measurement plane 26A. Each plate is linked at the middle. Eight adjusting bolts 38 extending toward the second plate are secured to the third plate 26 around a shaft. The adjusting bolts 38 are screwed with first nuts 42 on the third plate side of the second plate 24, and screwed with second nuts 44 on the first plate side. Since the third plate 26 can be deflected by positioning the nuts, the nuts are positioned so that the measurement plane 26A does not deflect in the axial direction when the wheel 20 turns. A tire posture of the running vehicle can be accurately measured, because a runout of the measurement plane 26A can be reduced when delivering a laser beam to the measurement plane 26A of the running vehicle to measure the tire posture.
