Abstract
A throttle valve control device for an internal combustion engine is obtained which has an improved sector gear capable of suppressing inclinations of tooth surfaces of its resin teeth due to shrinkage of a resin upon hardening thereof at the time of insert molding. The throttle valve control device includes a motor and the sector gear operatively connected with the motor for driving a shaft , on which a throttle valve is fixedly mounted, by means of power transmitted thereto from said motor. The sector gear has a sector-shaped rigid core member , and a resin molded portion with the teeth formed on the core member by insert molding. The core member has a support portion with a curved surface formed to extend along bottoms of the teeth and project in an axial direction as well.
