Abstract
PURPOSE: To prevent return force deficiency and an overrun by fitting either of a permanent magnet and magnetic material to a shaft of revolution and fixed part to provide maximum magnetic suction force at a neutral point position and by enabling the return and stop at the neutral-point securely by using a return spring together.
CONSTITUTION: To operating shaft 3 of the control operation device that returns automatically, permanent magnet 13 having both poles N and S projected facing the reciprocal outsides is fixed and to case 1, yoke 14 is fixed, opposing to the magnetic poles of this magnet 13 and facing inward, at the position where they pull magnetically each other. Around shaft 3, torsion spring 10 is arranged by spring bearings 11 and 12. Then, either of magnet 13 and yoke 14 is enabled to provide maximum magnetic suction force at the neutral-point position and initial force is applied by spring 10 as long as handle 4 is made free from the hand to provide damping action near the neutral-point position by magnetic force, thereby preventing an overrun and virbration.
