摘要： PROBLEM TO BE SOLVED: To provide a thrust bearing to be slid, while being sufficiently lubricated, at low cost without requiring much of resources, in a scroll compressor.SOLUTION: The thrust bearing includes a ring shaped thrust plate 15 arranged between an oscillating scroll 3 and the bottom 12a of a frame 12, and a ring shaped thrust surface formed projecting downward from the outer circumferential side of the bottom surface of the base plate 3a of the oscillating scroll 3. The orbital motion of the oscillating scroll 3 makes an area of the thrust surface projecting from the thrust plate 15 be present at all times, causing the projected surface to slide on the thrust plate 15 after being exposed to a space filled with oil. The same number of repetition of this movement as the number of rotation per second allows the thrust surface of the oscillating scroll 3 to slide on the thrust plate 15 in a lubricated state.
