The throttle valve shaft 3 is rotated by a motor M via an intermediate gear Na which has a large diameter part Nb and small diameter part Nc. The motor gear Ma meshes with large diameter gear Nb while the small diameter part Nc meshes with a drive gear Ka on the throttle shaft 3. In order to make the throttle valve control device compact, eg for application to two- or three-wheeled vehicles, the large diameter gear Nb is an internal gear, eg having a bottom part Nd surrounded by a cylindrical wall part Ne. |
