  • Patent number: 8222782
    Abstract: Disclosed is a brushless motor which allows easy positioning of an air core coil and facilitates quick assembling of the coil because the air core coil is positioned by fitting an air core portion of the air core coil to bosses formed in a coil plate. Moreover, since no jig is required for the positioning of the coil, the positional precision of the coil can be stably attained, thereby enhancing the positional precision of the coil. Furthermore, although the positioning of the coil becomes difficult as the coil is reduced in size, the present invention is capable of easily coping with the thinning and miniaturization of the coils, i.e., thinning and miniaturization of the motor. In addition, the thinning and miniaturization of the motor can also be attained by arranging a circuit board and a coil plate in parallel to each other.

  • Patent number: 7883423
    Abstract: 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.
