A torque detector includes: a magnetic flux collecting unit including a magnetic flux collecting holder formed in an annular shape by resin molding and a magnetic shield formed by bending a metal plate and attached to an outer peripheral face of the magnetic flux collecting holder; and a sensor housing formed integrally with the magnetic flux collecting unit. The magnetic shield has a shield body, a shield end portion, and a bent portion. A second angle formed between an outer side face of the shield end portion and a radial direction is smaller than a first angle formed between an outer peripheral face of the shield body and the radial direction.

Torque detector and steering system including the torque detector

An electric power steering device includes a power transmission joint () which coaxially couples an output shaft of a steering assist electric motor to an input shaft of a speed reduction mechanism for power transmission. The power transmission joint () includes first and second engagement members () and an elastic member () disposed between the first and second engagement members (). The elastic member () includes an annular main body () and a plurality of engagement arms () provided at a predetermined interval circumferentially of the main body (). The engagement arms () are engaged with engagement projections () of the first and second engagement members () circumferentially (X) of the main body (). Power transmission faces () of the engagement arms () include power transmission faces () each having a relatively great interference (d) and power transmission faces () each having a relatively small interference (d).

A shaft coupling mechanism for an electric power steering apparatus includes a coupling base body coupled to a rotating shaft; a coupling base body coupled to a steering shaft serving as a rotating shaft; and a rotation transmitting member which is disposed between the both coupling base bodies and transmits the rotation of the coupling base body in a direction about the axis, i.e., in an R direction, to the coupling base body as rotation in the R direction.
