摘要： An air-intake control apparatus of an internal combustion engine formed by attaching a flange portion provided to an end portion of a drive motor to a cylindrical hole portion. A throttle body has at least one positioning projection (or recess) provided to an inner wall of the cylindrical hole portion. The drive motor complementarily has at least one positioning recess (or projection) provided to the flange portion at a position corresponding to the positioning projection (or recess). The drive motor is attached to the cylindrical hole portion while the positioning recess (or projection) abuts on the positioning projection (or recess) in such a manner that a center distance between a motor shaft and a throttle shaft takes a predetermined value. Hence, not only attachment workability but also attachment accuracy of the drive motor can be enhanced. The air-intake control device therefore has higher product reliability.

摘要： A rotation angle detection apparatus is capable of preventing an eddy current and radio wave noise from being transmitted from outside to a yoke and a permanent magnet through a metal plate, and thence to a non-contact sensor through radiation as it is. The apparatus includes a yoke, a permanent magnet that is arranged on an inner wall surface with magnetic flux flowing from its N pole to its S pole through an inner space thereof, a metal plate formed integral with the yoke and the permanent magnet through a resin by insert molding, and a non-contact sensor arranged in the inner space of the permanent magnet. Between the metal plate and the individual end faces of the yoke and the permanent magnet, there is interposed a high impedance member that prevents radio wave noise from flowing from the metal plate to the yoke and the permanent magnet.

摘要： An intake air quantity controlling device for an internal combustion engine that includes a shaft, a throttle valve, a final spur gear, a drive motor, a full closure stopper, a full opening stopper, and a collision portion. The shaft is rotatably provided across an intake passage. The throttle valve is fixed to the shaft. The final spur gear is fixed to an end portion of the shaft. The drive motor applies a rotational force to the final spur gear. A full closure stopper determines a full closure position of the throttle valve, and full opening stopper determines a full opening position of the throttle valve. The final spur gear is provided with the collision portion, which collides with the full closure stopper and the full opening stopper to stop rotation of the final spur gear. The collision portion has a notch portion formed therein, defining a full-closure-side collision member that is elastically deformed through collision with the full closure stopper and a full-opening-side collision member that is elastically deformed through collision with the full opening stopper.
