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 device is simple in structure and is capable of reducing the size of a permanent magnet. The permanent magnet is fixedly secured to a rotating member. A first guide member is attached at one end face to an S pole side of the permanent magnet. A second guide member is attached at one end face to an N pole side of the permanent magnet, and has its tip end disposed in opposition to a tip end of the first guide member. A magnetoresistive member is disposed in a space between the tip ends of the first and second guide members, the magnetoresistive member being fixedly attached to a non-rotating member. An angle of rotation of the rotating member is detected by detecting a change of the azimuth of magnetic flux, which is generated by the permanent magnet in the space, by means of the magnetoresistive member.
