PROBLEM TO BE SOLVED: To provide a wheel alignment measuring device having a simpler constitution and, moreover which is capable of precisely measuring the toe angle and the camber angle. SOLUTION: The wheel alignment measuring device for measuring the wheel alignment with noncontact type comprises a laser beam irradiating means, mutually positioning vertically for forming bright line patterns, by making irradiate the side of the wheel with a pair of laser beams irradiated horizontally; an image acquisition means, arranged outside of the laser beam irradiation means in the same surface of the laser beam for acquiring the bright line patterns as the measuring images; an image processing means which compares the shape of the bright line patterns of the acquired measuring images and the registered images registered previously, and searches the registered images having higher than a certain value of correlation rate among the registered images, for determining and registering the images; and a calculation processing means for calculating the wheel alignment, based on the registered position data.
