Abstract:
1. A throttle valve control device wherein one end of a throttle valve shaft, which crosses an intake passage, is rotatably supported by a throttle body and is mounted with a throttle valve for opening/closing the intake passage, is provided projecting toward one side direction from an one side wall of the throttle body; the one end of the throttle valve shaft fixedly has a throttle valve lever, which is given opening directional energizing force of the throttle valve by a throttle valve lever open spring, and rotatably has a drive gear including a drive pin facing the throttle valve lever; the drive gear is geared and connected with a motor gear rotated synchronously with an output shaft of a motor, through an intermediate gear; one end of a drum shaft rotatably supported by a first cover fixedly has an accelerator drum, which is given closing directional energizing force of the throttle valve by a drum close spring, and another end of the drum shaft fixedly has a limp opening control lever facing the throttle valve lever; the limp opening control lever has a limp opening control end face facing a first opening directional end face of the throttle valve lever; the first opening directional end face of the throttle valve lever is contacted with the limp opening control end face at the time of a full closing position of the limp opening control lever so as to control a limp opening of the throttle valve; and the drive pin provided at the drive gear is provided facing a second opening directional end face of the throttle valve lever, and rotates and controls the throttle valve lever in the opening/closing directions of the throttle valve by the drive pin corresponding to rotation of the drive gear.
