Claims

[Scope of utility model registration request]

A throttle body is provided in the middle of an intake passage of an engine and has an air passage that constitutes a part of the intake passage, and a throttle valve is installed in the air passage of the throttle body and adjusts the air flow rate in the air passage. a control cam that is rotatably installed on the throttle body and finely adjusts the throttle valve during warm-up operation of the engine; and a wax pellet that is attached to the throttle body and that rotationally adjusts the control cam according to the engine cooling water temperature. In the throttle valve control device, the control cam includes a cam support cylinder portion formed by reducing the diameter at one end, and a plate-like body having a fitting hole, the fitting hole being connected to the cam support cylinder. It consists of a cam plate part that rotates together with the cam support cylinder part by fitting into the reduced diameter part of the part and fixing by caulking, and the reduced diameter part of the cam support cylinder part has a locking notch. A throttle valve control device characterized in that a locking protrusion is provided on the periphery of the fitting hole of the cam plate portion, into which the locking notch is fitted during caulking.
