Patent ID: RE40382

Claim:
An apparatus for controlling a throttle valve electronically in an internal combustion engine, comprising: a) a main body; b) a throttle valve installed in an intake air passage of an internal combustion engine; c) an actuator to control said throttle valve to open/close; d) a supporting member to fasten a body of said actuator to said main body on an output side of said actuator; e) a cover member to cover said body of said actuator and which is supported near a non-output side of said actuator by the main body, the body of said actuator having a predetermined gap to said cover member; and f) an elastic member in said predetermined gap on said non-output side of said actuator , wherein said elastic member is placed between a plane perpendicular to an output axis of said actuator and inside of said cover member so as to restrict axial movement of said elastic member in an axial direction of the output axis of said actuator between the plane perpendicular to the output axis of said actuator and the inside of said cover member .
