PURPOSE: A structure of an oil storage tank is provided to eliminate additional components such as a cooling tube by adding a radiating function to the outside of the oil storage tank. CONSTITUTION: An oil storage member(20) comprises a housing(20a) and a supply port(20b). The housing forms a sealed space to store operating oil. The supply port is formed in the lower part of the housing to be connected with the outside. A radiating member(30) comprises a housing(30a), a moving passage(30d), many radiating pins and a collecting port(30f). The housing(30a) is formed to accept the oil storage member therein. The moving passage is formed through the inner circumference of the housing spirally. The radiating pins are formed outside the moving passage. The collecting pot is connected with the outside under the housing. The oil storage member is connected through the moving passage. Thereby, an additional cooling tube is unnecessary and the degradation of components is prevented.
