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.

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： 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.
