PROBLEM TO BE SOLVED: To detect the correct level of fuel by providing a fixing portion provided above the oil level of a fuel tank filled to capacity and an oil meter arranged in the fuel tank fixed to the fixing portion. SOLUTION: A detection section 27 is provided at the lower end of a support section 26 drooping from a fixing section 23 provided on the top face of a fuel tank 20, and only by adjusting the length of the support section 26, the position of the detection section 27 can be adjusted easily, and the range of detection of the quantity of residual oil of the oil meter 25 can be set broadly. The fixing section 23 is set near the corner of the side of the fuel tank 20 and in a position where the distance between facing sides is long, the length of an arm 28 can be set long, and the range of detection of the quantity of residual oil can be increased. As the fixing section 23 is provided in the upper portion of the fuel tank 20 and does not sink into fuel, fuel does not leak from the fixing section 23.
