According to the present invention, in a preparation step, a frame (10), a concave spherical surface seat (15), a convex spherical surface seat (13), a rotary body (16), a swinging shaft (12), and a workpiece holder (17) are assembled with each other, a laser head (33) is mounted to the convex spherical surface seat (13), and a light receiving unit (38) is mounted to the workpiece holder (17). In a rotary body centering step, while irradiating a laser irradiation surface (41) with a laser beam (LB) emitted from a laser head (33), the rotary body (16) is rotated to change the irradiation position of the laser beam (LB) with respect to the laser irradiation surface (41), and the trajectory of the irradiation position is confirmed.
