PROBLEM TO BE SOLVED: To easily fix an optical component in desired posture with simple constitution. SOLUTION: A flange part 11 having an arc-shaped outer edge provided at the lower end of a base 1 is fit in the circular hollow 101 of a base plate 100, and the base 1 is fixed on the base plate 100 through a screw 103 piercing through a slot 112 while adjusting a rotational angle around a perpendicular axis. A front side screw 5 and a rear side screw 6 are alternately tightened from a state where they are temporarily loosened, and a holder 2 is fixed on the base 1 in such a state that the rotational angle with a right-and-left direction to the base 1 as the axis of rotation is adjusted to a desired angle. The holder 2 is supported by the upper ends of a left side hard ball 3 and a right side hard ball 4 arranged between the holder 2 and the base 1, and the holder 2 is fixed on the base 1 in such a state that the rotational angle around an axis in a right-and-left direction linking the upper end of the left side hard ball 3 and the upper end of the right side hard ball 4 is adjusted to an optional angle by properly setting the ratio of force applied to the holder 2 from the front side screw 5 and the rear side screw 6.
