In order to improve a trailer coupling, comprising a ball neck, which is movable between a working position and a rest position and has a pivot bearing body arranged at a first end and a coupling ball arranged at a second end, a pivot unit, which is arranged fixed to a vehicle and by means of which the pivot bearing body is pivotal for the purpose of performing a pivotal movement about a pivot axis between a working position and a rest position, wherein the pivot unit comprises a pivot bearing unit fixed to the vehicle and a rotation-blocking device for blocking a pivotal movement of the pivot bearing body about the pivot axis, at least in the working position, the improvement being such that this susceptibility to faults in a trailer coupling of the kind mentioned in the introduction is avoided, it is proposed that a pivot control unit should be integrated within the pivot unit.

Disclosed is a motor comprising: a stator; a rotor provided inside the stator; and a shaft coupled to the rotor, wherein the stator comprises a stator core, a coil wound around the stator core, and an insulator arranged between the stator core and the coil, and the insulator comprises an upper insulator and a lower insulator. An upper body of the upper insulator comprises: a first side wall part; a second side wall part arranged to the spaced apart from the first side wall part; and a first cover part extending from an end of the first side wall part and connected to an end on one side of the second side wall part, wherein the number of a plurality of first grooves formed on the first side wall part is different from the number of a plurality of second grooves formed on the second side wall part. Accordingly, when a coil with an increased diameter is used, the performance of the motor can be improved by implementing asymmetric wiring of the coil by using the insulator for guiding the arrangement of the coil.

In an electric rotating machine apparatus according to the present disclosure, noise-removal capability is secured by adopting a structure in which an external terminal is connected with a protruding portion, of a control circuit board in a control unit, that protrudes from a through hole of an electromagnetic shield and in which a filter unit is provided. Because a conventional dedicated wiring board for mounting the filter unit thereon is not required, the foregoing structure can contribute to downsizing and cost reduction. In addition, the foregoing structure can contribute to downsizing and cost reduction of an electric power steering apparatus equipped with the electric rotating machine apparatus according to the present disclosure.
