Abstract:
A rotational-position sensing device comprising:a stationary body including a switching pattern; a rotator rotatably supported by said stationary body, said rotator having a driving-side engaging means, said switching pattern being provided around a rotational axis of said rotator; and a follower receiving a rotational force to rotate about said rotational axis from said rotator through said driving-side engaging means, said follower being made of an electrically conductive metal plate, said follower having a plurality of contact terminals integrally formed in said electrically conductive metal plate, said follower further including a driven-side engaging means that receives said rotational force from said rotator during rotation of said rotator in a forward rotational direction upon engagement with said driving-side engaging means in a forward rotational engaged position, wherein: said rotational-position sensing device senses a rotational position of said rotator through engagement and disengagement of said contact terminals with said switching pattern based on rotation of said follower; and said driven-side engaging means has a play, said play allowing said driving-side engaging means to move away from said forward rotational engaged position without transmitting said rotational force to said follower when said rotator rotates in a backward rotational direction.
