<p>PURPOSE:To aim at prevention of the movement of a rotary shaft in an axial direction by inserting a pin having a screw into a through hole provided at a movable core, screwing it into a screw hole provided at the flange portion of a yoke and pressing the outer ring of a bearing at an opposite load side by the end of the pin. CONSTITUTION:A plurality of screw holes 1c are provided at intervals in a same direction at the flange portion 1b of a yoke extended to the bearing 5 side at an opposite load side. Through holes 2a corresponding to the respective screw holes 1c are provided at a movable core 2 and a pin 7 having a screw is screwed into the screw hole 1c via the through hole 2a. The outer ring of the bearing 5 at an opposite load side is pressure by the end of a screw 7. Respective through holes 2a have a slightly larger diameter than the head of the pin 7 and functions as the guide of the movable core 2. Accordingly, the movement of a rotary shaft 6 in an axial direction can be prevented so that is becomes possible to maintain a set stroke S constant.</p> |
