ABSTRACT:
A tank cap for closing the filling port of a fuel or lubricating oil tank of a power-driven portable machine such as a chain saw. The tank cap is made of a transparent plastic material and is provided with a protrusion protruding outwardly from the main surface of the tank cap. The cavity formed in the protrusion is communicated with the tank filling port so that the fuel or lubricating oil is allowed to come into this cavity. Consequently, the fuel or lubricating oil level can be visually checked from all directions around the tank cap.
