摘要： A torque detection device has a magnetic flux collecting ring, arranged outside an outer periphery of a magnetic circuit forming member which is provided in a rotating body applied with a torque, for collecting a magnetic flux generated by the magnetic circuit forming member; a detector for detecting the torque applied to the rotating body based on a density of the magnetic flux collected by the magnetic flux collecting ring; and a holding ring for holding the magnetic flux collecting ring and the detector and including an attachment part to be attached to a stationary object on an outer periphery on one side in a radial direction. An attachment-preventing convex part for preventing attachment to the stationary object by contacting the stationary object is formed on one end face in an axis line direction of the holding ring.

摘要： In order to solve a problem of an electric power steering device of an automobile that the steering feeling is deteriorated by dragging the inactive electric motor if a steering member is operated at a small angle to leave an electric motor inactive while the automobile is running straight, the present invention provides a joint for jointing the rotary shaft of a steering assisting electric motor and a worm shaft of a reduction mechanism, comprising a first member rotating integrally with the rotary shaft; a second member rotating integrally with the worm shaft; and an elastic member for coupling the two members in a torque transmittable manner. The elastic member has a relatively small elastic modulus according to the state that the torsion angle between the first and second members is small. Accordingly, the structure and characteristics thereof lead to a better operationality of the steering member.
