PROBLEM TO BE SOLVED: To surely open/close an opening/closing valve at desired timing when a communication hole is opened and closed using the opening/closing valve having large opening/closing motions.SOLUTION: An oil pan (1) is equipped with a partitioning member (20) to partition the internal space of the oil pan body (10) into a first chamber (R1) and a second chamber (R2), and has the communication hole (21) making the first chamber (R1) and the second chamber (R2) communicate each other, the opening/closing valve (30) to open and close the communication hole (21), and a valve driving member (50) to drive the opening/closing valve (30). The valve driving member (50) is formed from a long-stretching bi-metal. The oil pan (1) is equipped with an adjusting mechanism (39) to adjust the energizing force of the valve driving member (50) so that it energizes the opening/closing valve (30) in the closing direction with the prescribed force when the temperature of the oil is below the prescribed level. |
