Claims

[Scope of utility model registration request]

The thrust receiving pad is fitted onto the rotating main shaft through an axial hole, and can restrict movement of the rotating main shaft in the axial direction by thrust receiving pad surfaces provided on both sides in the axial direction, and the pad surface communicates with the axial hole. In a thrust bearing having a plurality of pad grooves extending radially, a pad contact surface, and a tapered pad surface formed between the pad grooves and the pad contact surface, the inner circumferential surface of the shaft center hole an inner circumferential groove is carved along the thrust bearing, an oil supply hole is bored inside the thrust bearing that extends in the radial direction and communicates with the inner circumferential groove, and the inner circumferential groove is formed near the starting point of each of the tapered pad surfaces. A thrust bearing characterized by forming a communicating through hole.
