PROBLEM TO BE SOLVED: To resolve a problem that measuring the angle of a center axis of a penetration hole to the center axis of a cylindrical body having a penetration hole near the center by using a low cost wire was hard.;SOLUTION: In the method for measuring the angle of an center axis of the penetration hole to the center axis of the cylindrical body having the penetration hole at near the center, a column body is inserted in the penetration hole of the cylindrical body and projected. It is stopped while the cylindrical body is rotated, and from the vibration width of the column body tip end projecting from the penetration hole, the angle is obtained.;COPYRIGHT: (C)2006,JPO&NCIPI
