ABSTRACT:
The invention is directed to a throttle control apparatus for use in an internal combustion engine. The apparatus includes an accelerator operating mechanism, a driving source, and a supporting member secured to an end portion of a throttle shaft extending out of a housing. A rotor is rotatably mounted on the throttle shaft, and connected with the driving source to be rotated thereby. A movable member is mounted on the throttle shaft between the rotor and the supporting member to be axially movable. A connecting member is disposed for connecting the movable member with the supporting member, and biasing the former toward the latter. An electromagnetic coil is disposed to face the rotor. There is provided an engaging member which has a base end mounted on the movable member for supporting the engaging member rotatably within a predetermined angle range. A driving member having an end face engageable with the engaging member is mounted rotatably about an axis parallel with the axis of the throttle shaft, and connected with the accelerator operating mechanism. The engaging member has an axial length engageable with the end face of the driving member only when the movable member is positioned at the side of the supporting member.
