PROBLEM TO BE SOLVED: To perform a correction after obtaining corrected data of a high reliability. SOLUTION: This oil feeding device is equipped with a first storage means 35 and a table converting means 36. In this case, the first storage means 35 integrates oil feeding amounts at the ends of respective oil feeding works by a meter 4. Also, the first storage means 35 stores the integrated value at the stage wherein the integrated value has exceeded a specified value, and a liquid level from a liquid level detecting means at this time. The table converting means 36 calculates a liquid amount at each liquid level by a relative liquid amount wherein the liquid amount at the applicable point is taken as zero, by the data of the first storage means 35 at a stage wherein the liquid level of a tank rises by a replenishment from the outside. Then, a tentative table is prepared. Also, the table converting means 36 prepares correction data which corresponds with reference data by interpolation-computing, and updates the reference data.
