PURPOSE:To provide an angle variation device of a ball joint capable of applying to a capillary inspection device capable of passing through a bent part or a branching part of a capillary part. CONSTITUTION:Inside of a spherical body storage member 2 of a ball joint, three sets of oscillators 3 assembled with three pieces of oscillating elements are arranged in a specified arrangement. As these oscillators 3 are rotated in the specified direction in the state being made contact with a spherical body 1 of a ball joint, the spherical body 1 is rotated, and angle of the ball joint is varied. In the meantime, it is possible to increase the number of the oscillators more than four pieces as required. |
