PURPOSE:To move a probe to a shunting position precisely by shunting the probe by rotating a supporting arm by impact force at the engagement of a balance weigt with an engaging member. CONSTITUTION:Since the probe is shunted by rotating the supporting arm 13 by the impact force at the engagement of the balance weight 14 with the engaging member 16, only a piston in an air cylinder 11 is a sliding part. Since there is no influence due to centrifugal force, especially influence due to the increment of frictional force, the probe 10 is precisely moved to a shunting position separated from a material S to be tested. |
