The throttle valve lever basically includes an oblong structure comprising synthetic resin and an oblong reinforcement plate comprising metal. The resin structure has a hole defined therethrough, which is capable of fitting around the shaft of a throttle valve of a carburetor, and also has a lever portion at one end of the resin structure. The metal plate has a hole defined therethrough, which is capable of fitting around the shaft of a throttle valve of a carburetor, and also has a lever portion at one end of the metal plate. The metal plate is embedded within the resin structure such that the lever portion of the resin structure and the lever portion of the metal plate are correspondingly situated, the hole of the resin structure and the hole of the metal plate are aligned, and the metal plate is exposed at the metal plate hole and is capable of direct and fitted contact with the throttle valve shaft.
