To provide an electronically controlled throttle control device capable of reducing a rotational load of a driving motor and preventing malfunction of a throttle valve 3 by extensively decreasing sliding resistance between the periphery of a spring inner peripheral guide 53 of a valve gear 9 and the inner periphery of a default spring 62 of a piece of coil spring 6.
An offset amount (rotational deformation amount) of the default spring 62 generated when the other end of the spring 62 is set in a second locking part provided in the opener member 52 of the valve gear 9, and a U-shaped hook part 63 is set in a locking part 55 in the opener member 52 is previously added in the opposite direction when the coil spring 6 is formed, thus reducing the offset amount generated when the spring 6 is set in the control device.
