Abstract
PURPOSE:To lengthen the service life of rotation, by making the diameter of a flange at the end of a support for fixing a target board longer than the circumferential diameter where a rotor and a small screw for coupling a rotary shaft are arranged. CONSTITUTION:A rotary shaft 5 fixed with a support 3 and a rotor 2 are coupled through a small screw 6 while the rotary shaft 5 is supported through a bearing 7 to a fixed section 8. A target board 1 is mounted on a flange 9 at the end of the support 3 then secured by a nut 4a. The diameter of the flange 9 is made longer than the diameter of circumference on which a small screw 6 is arranged while a notch 10 is provided at the position of the outer circumference of the flange where the small screws 6 are arranged. A seat feeding section 11 is provided at the portion of the flange 9 where the notch is not provided, thus to make the target board 1 touch said section 11. Consequently the flange can be enlarged without disabling the fastening of the small screw to secure the target reliably thus to lengthen the service life of the rotation.
