Title: Rotary sensor having elastic members for pressing rotor in axial andnon-axial directions

Abstract: The structure is arranged such that between the supporting portion 1e ofthe casing 1 and the collar portion 2s of the rotor 2, there is displacedthe second elastic member 4 for pressing the collar portion in the axialdirection of the driving shaft 10, that the pressing force of the secondelastic member is greater than the frictional force to be generatedbetween the driving shaft and the first elastic member 5 when the drivingshaft moves in the back-and-forth direction of the axial direction, andthat the rotor is prevented from moving forward by the pressing force ofthe second elastic member when the driving shaft moves in the forwarddirection to go out of the rotor 2.
