PROBLEM TO BE SOLVED: To provide a thrust slide bearing made of synthetic resin, capable of increasing a decrease amount of a volume of filled fluid to cause the fluid to generate a larger pressure and thus reducing a slide friction resistance.SOLUTION: A thrust slide bearing 1 includes an upper case 2 made of synthetic resin, a lower case 41 made of synthetic resin, and a thrust slide bearing piece 71 made of synthetic resin and provided between the upper case 2 and the lower case 41. An upper annular face 75 of the thrust slide bearing piece 71 has a center annular concave surface 87. An annular concave portion 84 serves as a stagnation part for lubricant such as grease. |
