摘要 PURPOSE:To intend the prevention of the backflow of a lubricating oil to its communicating passage and the increase in the amount of the lubricating oil to a sliding surface by providing a throttle mechanism for restricting the flow of the lubricating oil from the side of an oil feeding passage of an oil chamber to the side of a communicating passage between the oil chamber and oil feeding means when a sliding body moves forward. CONSTITUTION:There are provided throttle means 20 and 21 for restricting the flow of a lubricating oil from the side of an oil feeding passage 14 formed in a thrust bearing 7 in an oil chamber 12 for communicating the sliding surface 7a thereof with the oil chamber 12 to the side of a communicating passage 13 for communicating the oil chamber 12 with crank oil feeding means 11 when a sliding body moves forward. Thus, the lubricating oil staying the side of the oil feeding passage 14 in relation to the throttle mechanism 20, 21 in the chamber 12 becomes difficult to flow out to the side of the communicating passage 13 in the oil chamber 12, due to a large flow resistance caused by the throttle mechanisms 20, 21. Accordingly, the lubricating oil in the oil chamber 12 can be prevented from flowing back to the communicating passage 13 as much, and the amount of feeding oil to the sliding surface 7a of the thrust bearing 7 can be increased.
