PROBLEM TO BE SOLVED: To carry out a work for adjusting an antenna shaft by a minimum operation by adjusting a position of an antenna shaft adjusting tester to remove a deviation angle of a vehicle set and correcting a final deviation angle error of the antenna shaft by a signal processing soft of a radar. SOLUTION: An antenna shaft adjusting tester 20 is opposed to a vehicle by an optical collimator 33, a rail 21 is moved to sight a laser level 30 to a front surface of the antenna with a mirror by a visible laser, and thereafter, an angle rotation plate 31 is reverse-rotated by an angle corresponding to a vehicle inclination deviation angle. As a result, an irradiation direction of the laser level 30 becomes a geometrical center axis direction of the antenna. So, since the antenna shaft is parallel to a vehicle axis, the antenna shaft adjustment is completed. Thereby, in a limited working space such as a car manufacturing line and a maintenance factory, the antenna shaft of a milli wave radar can be easily and accurately adjusted.
