ABSTRACT:
An improved rotary direction detecting sensor to be used for a vehicle. It includes a stationary member including a cylindrical extension, a movable member fitted on a rotor and rotatable in the same direction associated with the rotor, the rotor being rotatably fitted to the stationary member on its cylindrical extension, while the stationary member is kept unrotatable irrespective of the rotation of the rotor, and a follower member interposed between the stationary member and the movable member. The follower member has a cut-out engaged with a corresponding projection formed on the movable member to delay the rotation of the follower member for a predetermined angle with respect to the rotation of the movable member. Both the movable member and follower member are provided with separate connecting contacts, while the stationary member is provided with a group of contacts selectively contacted by the connecting contacts depending on the rotary direction of the rotor.
