Abstract
In a throttle device for automotive engines, a throttle shaft is position-regulated in the axial direction by a position regulating part of a throttle body at a side where a contact unit of a rotation position sensor is provided. Thus, the distance of axial movement of the contact unit is limited. Thus, the rotation position of the throttle shaft can be detected accurately by the rotation position sensor for the accurate control of the throttle valve opening angle, even when the surrounding temperature changes caused by heating of the engine and a throttle driving motor.
