    摘要： A fail-safe mechanism of an air induction control apparatus for automotive engines is provided which is designed to hold a throttle valve at a middle position when a valve actuator has failed to move the throttle valve. The fail-safe mechanism includes a middle position hold stopper, an opener lever connected to the throttle shaft, and a first and a second coil spring. The first coil spring works to exert a first spring pressure on the opener member in a first rotational direction in which the throttle valve is rotated from a fully opened position to the middle position. The first coil spring is urged at an end thereof into constant engagement with the middle position hold stopper to hold the opener member from rotating in a second rotational direction opposite the first rotational direction. The second coil spring has a first and a second end between which the opener member extends. The first end abuts against the middle position hold stopper. The second end abuts against the opener member so as to exert a second spring pressure on the opener member in the second rotational direction to nip the opener member between the second end of the second coil spring and the end of the first coil spring elastically through the first and second spring pressures, thereby holding the throttle valve at the middle position.

    摘要： A rotation-angle-detection device (28) includes a main housing (15), a resinous cover (24) for covering an opening of the main housing (15), a permanent magnet (22) disposed at the main housing (15) to be rotatable in response to rotation of a throttle valve (11), and a magnetic sensor (25). The cover (24) is longer in longitudinal direction than in lateral direction, and the magnetic sensor (25) is fixed to the resinous cover (24). The magnetic sensor (25) is disposed so that the detection direction and the longitudinal direction of the cover (24) cross each other at a right angle.

    摘要： A hollow-cylindrical heat conduction portion (44) is formed on a throttle body (42) in such a way as to protrude outwardly therefrom in the radial direction. The throttle body (42) and the heat conduction portion (44) are integrally formed using metal material such as aluminum having excellent heat conductivity or resin material containing such a metal material. A vent hole (31) communicating the interior with the exterior of a head cover (3) is formed in the head cover (3). Through the vent hole (31) there is inserted the heat conduction portion (44), and the clearance between an outer-peripheral wall thereof and an inner wall of the vent hole (31) is sealed by means of a seal member.
