PROBLEM TO BE SOLVED: To provide an oscillating object restraining mechanism which does not produce reactive force to the other axis. SOLUTION: An oscillating object restraining mechanism restrains the movement of an oscillating object 113 which moves along a spherical surface seat 111. The oscillating object restraining mechanism comprises a cut surface 119 with a cylindrical surface formed on the oscillating object 113 and a pushing member 115 having the leading end of which is in the shape of a spherical surface and coming into contact with the cut surface 119.
