<p>PROBLEM TO BE SOLVED: To sufficiently reduce oil flow resistance to reduce energy consumption needed to drive an oil pump.SOLUTION: In a lower wall part 41 of a casing 20, an oil inflow pipe part 43 is formed so as to extend downward. In an upper wall part 31 of the casing 20, an oil outflow port 33b is formed. A filter 10 is formed so as to extend while inclining along the longitudinal direction of the casing 20. An oil flow passage R is formed so as to gently curve from the oil inflow pipe part 43 to a portion where the filter 10 is arranged in the casing 20.</p> |
