Abstract

Torque sensor including a multipolar magnet portion rotated together with a steering shaft, a magnetic yoke portion rotated together with a column shaft connected to the steering shaft via a torsion bar and arranged in the field of the multipolar magnet portion, a set of magnetism collecting plates and having a set of magnetism collecting plate bodies and that collect lines of force of the pair of magnetic yokes and of the magnetic yoke portion respectively and a pair of magnetism collecting protrusions and extending from the set of magnetism collecting plate bodies and respectively in the axial direction of the steering shaft to form a gap, and a detection unit having a detection surface the normal line of which is in a radial direction of the steering shaft, disposed so as to face the gap of the pair of magnetism collecting protrusions, and detecting a flux in the gap.
