PURPOSE: An oil tank used in hydraulic equipment is provided to reduce wet and rust generated in the oil tank and to expand a life span of oil by preventing rust from flowing into a filter. CONSTITUTION: An oil tank(30) includes a fan(80) at an upper portion thereof to reduce wet. The fan(80) is communicated with a housing(32) of the oil tank(30) through a duct(82). The duct(82) is connected to an upper surface of the housing(32). An air suction hole(70) is formed at the upper surface of the housing(32) in opposition to the fan(80). A filtering member(72) is provided in the air suction hole(70) in order to filter impurities introduced into the oil tank(30). A bottom surface of the housing(32) is inclined to prevent rust from flowing into the filtering member(72). The bottom surface of the housing(32) is downward inclined from the filtering member(42) towards one end of the housing(32).
