ABSTRACT:
An intake control device for an engine includes a throttle body that defines a throttle bore, which is substantially circular-shaped in cross section, through which intake air flows. A throttle valve is rotatably assembled in the throttle bore of the throttle body. The throttle valve rotates integrally with a shaft. One axial end of the shaft is connected to a rotary driver, so that the rotation angle of the throttle valve is changed via the shaft. The rotary driver defines a fitted hole, to which the one axial end of the shaft is clearance fitted. The rotary driver defines a fitting recess dented radially outward from the hole wall surface of the fitted hole. The one axial end of the shaft includes a coupling that is crimped and fixed to the rotary driver in the state of being fitted to the fitted hole.
