[0018] In this embodiment, the thrust bearing main body 2 is fixedly connected to the inside of the engine cylinder block through the bearing block 1. When it is necessary to adjust the position of the thrust bearing main body 2 to adjust the distance between the thrust bearing main body 2 and the crankshaft, first rotate the adjusting bolt 6.
