Since the pressure in the outlet port 31 inevitably increases,
The pressure causes the relief valve 33 to rise so as to communicate between the second outlet port 31 and the bypass port 32. Therefore, oil in the housing 16 that cannot pass through the filter element 23 is removed from the second outlet port 31, the bypass port 32, between the upper and lower seal end plates 24 and 25, the first outlet port 30, and the center hole 29. Since the lubricating oil is sent out to the lubricating oil path 28 through the lubricating oil passage 28 in sequence, a predetermined amount of lubricating oil can be secured.
