A torque steering angle sensor is provided. The sensor includes a ring magnet with magnetic poles, magnetic path forming members to vary in location relative to the magnetic poles depending on torsion of a torsion bar, one pair of magnetic flux collecting rings for the magnetic path forming members, a first detecting element to detect a magnetic field between the flux collecting rings, a second detecting element to receive a magnetic field from the ring magnet, a slide magnet for producing a magnetic field in a different direction from that of the magnetic field of the ring magnet in the second detecting element, and a sliding mechanism to move the slide magnet toward or apart from the second detecting element with rotation of a rotary member of an electrically assisted power steering device. The second detecting element detects the magnetic fields received from the ring magnet and the slide magnet.
