摘要： A rotation angle detector includes a stator core (2) comprised of a plurality of core sheets (4) each having plural core members (4a) each including a tooth and a yoke portion (5a, . . . , 5h, 4b) disposed in a strip-like array with adjacent core members being coupled to one another by coupling means (4d) at yoke end portion. The core member is laminated. The stator core is shaped into an annular form by bending the core members at coupled portions so that the tooth portions extend centrally while capable of extending substantially linearly upon expansion thereof. An exciting winding (8) and output windings (9, 10) of n phases are wound on the tooth portions. A rotor core (3) is disposed rotatably relative to the stator core such that gap permeance between the rotor core and the tooth portions changes sinusoidally as a function of the rotation angle.

A connector base includes connection terminals connected with tip ends of the connection portions, a base portion with the connection terminals disposed on a surface thereof, and nuts mounted on the base portion. Leads have, at their one end, lead-side terminals in contact with the connection terminals. Screws are threaded on the nuts, respectively, for coupling the connection terminals and the lead-side terminals.

摘要： A vehicular steering system can suppress steering of steerable road wheels in a direction not intended by a driver. A steering mechanism steers the steerable road wheels in accordance with a steering wheel and an auxiliary steering angle superposition mechanism. A calculation section calculates a target auxiliary steering angle corresponding to a steering wheel angle of the steering wheel. A detection section accurately detects the auxiliary steering angle based on detection signals of a rotation angle sensor that detects a rotation angle of a rotational member. A driving section controls the auxiliary steering angle superposition mechanism so as to make the auxiliary steering angle coincide with the target auxiliary steering angle. An auxiliary steering angle detection abnormality monitoring section detects abnormality of the auxiliary steering angle detection section. The auxiliary steering angle detection section includes a counting section that counts the number of revolutions per minute of the rotational member.
