ABSTRACT:
A projecting portion, which projects from an outer surface of a bore portion, integrally has a full open stopper and a full close stopper. The full open stopper locks a throttle lever when a throttle valve is fully opened. The full close stopper locks the throttle lever when the throttle valve is fully closed. Moreover, the projecting portion has reinforcing rib portions for reinforcing the full open stopper and the full close stopper. Accordingly, the strength of the full open stopper and that of the close stopper are recovered each other, so that both stoppers can be downsized.
