Abstract: A stator is configured so as to have an annular shape by linking core blocks that are each produced by laminating electromagnetic steel sheets and that each have a yoke portion and a tooth portion by bendable first linking portion, concentrated winding coils are each produced by winding a conductor wire around the tooth portion for a number of turns so as to pass through concave spaces that are formed by the trunk portions and first and second guiding portions of first and second insulating bobbins, and current-carrying member holding portions that hold first current-carrying members that configure the concentrated winding coils into alternating-current connections are constituted by holding grooves that are each formed so as to open radially outward and so as to pass through the first guiding portions circumferentially, and that are arranged in three layers in an axial direction.

Abstract: In the intake air quantity control device, a ring-shaped convex portion having an outer diameter being smaller than an inner diameter of the wave washer for damping the drive motor is formed on the bottom surface of the cylinder-shaped hole of the throttle body, and tapered portions are provided at an outer-diameter corner of the ring-shaped convex portion and at an outer-diameter corner of the bottom surface of the cylinder-shaped hole of the throttle body.

Abstract: A range switching device includes: a range switching portion having an output shaft rotatably supported inside a housing and switchable to ranges corresponding to output shaft turning positions; a motor attached with its motor shaft spaced apart from a shaft center of the output shaft; a reducer mechanism linked to the motor and the range switching portion; and a control board controlling rotation of the motor. The reducer mechanism has a planetary gear reducer mechanism formed of a sun gear, planetary gears, an internal gear, and a carrier supporting the planetary gears, and a spur gear reducer mechanism formed of a pinion and a main gear linked to the pinion. The control board is installed oppositely to the output shaft and the motor.
