| Summary: | An intake air throttle valve device is capable of statically determining the opening of a throttle valve by balance between a driving force from a motor and an elastic force from an elastic member, thus making it possible to prevent the occurrence of a range in which it is impossible to control the opening of the throttle valve in accordance with the amount of electric power supplied to the motor. The intake air throttle valve device of the present invention is provided, in an intermediate portion of the elastic member with a load applying element for causing the elastic member to generate a force to oppose the force of a throttle gear thereby to apply a load to the throttle gear. The load applying element includes a third engagement portion, a first abutment portion and a second abutment portion. |
