Abstract
A rotation angle detection device for detecting a rotation angle of an object has a substantially cylinder-shaped yoke, a magnetism generation unit which is fixed to an inner surface of the yoke, a magnetism detection member which is arranged substantially in a center axis of the yoke, at least one bearing which rotatably supports the yoke, and a support member which holds the bearing. The yoke is made of a magnetic metal, and fixedly mounted at the object to be rotatable integrally with the object. The magnetism generation unit generates a magnetic field substantially perpendicular to the center axis of the yoke. The magnetism detection member generates an output corresponding to a variation of the magnetic field to detect the rotation angle of the object relative to the magnetism detection member.
