Abstract
The phase adjusting method is a method for holding a work including an end face formed symmetrical with respect to the axis of the work and a plurality of recesses respectively formed in a concave manner from the end face and also for positioning the position of each of the recesses around the axis of the work. Specifically, in the phase adjusting method, while holding the work in such a manner that it can be rotated around the axis thereof, the position of each of the recesses around the axis is detected. In accordance with the thus detected position of the recess around the axis, there is obtained a rotation angle by which the work is rotated around the axis thereof in such a manner the recess can be positioned at a given position around the axis of the work. And, based on the thus obtained rotation angle, the work is rotated around the axis thereof to position the recess at a given position around the axis of the work to thereby position the work.
