When the passage 11 is blinded by oil insoluble sludge 18, sufficient lubricating oil is not supplied to the inside of the bearing chamber 4, temperature of the bearing 3 rises, and temperature of the bearing holder 2 and the valve member 7 also rises. A clearance (d) is formed between the internal wall surface of the valve insertion hole 6 and the outer peripheral surface of the valve member 7 because of a thermal expansion difference of the bearing holder 2 and the valve member 7, the valve member 7 is energized downward by a compression spring 15, and the passage 12 opens in the lubricating oil chamber 8. Consequently, it is possible to supply sufficient lubricating oil to the bearing 3.
