PROBLEM TO BE SOLVED: To provide a thrust washer and a crankshaft support structure having enhanced durability and restraining friction and abrasion by local loading by enhancing absorptivity to deformation of a shaft or a bearing after installation. SOLUTION: The thrust washers 20 and 22 are formed by sandwiching a rubber material 28 between metallic plates 24 and 26. Thus, even if local pressure in the axial direction is generated when a deformation part 4b is generated on the journal bearing 4 side, the thrust washers 20 and 22 generate and absorb compressive deformation in the local thickness direction. Thus, since the pressure is widely dispersively transmitted to the opposed surface 10b side of a crankshaft 10, a local pressure increase to the crankshaft 10 side can be restrained. Since the sliding surface side is formed of a metallic material of any of the metallic plates 24 and 26, durability becomes high, and separation and a crack are hardly caused.
