ABSTRACT:
An end bearing used in an automatic transmission gear having a one-way clutch mechanism having multi-layers comprising a back metal, a copper alloy layer, a tin layer having a thickness of 0.5 to 4 .mu.m and a Cu-Sn intermetallic compound layer having a thickness of 0.5 to 4 .mu.m and having a Microvickers hardness of from 400 to 700, which intermetallic compound layer is positioned just under the tin layer and which intermetalic compound layer is are formed on the copper alloy of such an end bearing. According to the present invention, it is possible to improve anti-seizure characteristics of an end bearing even under a condition of a decrease in the amount of oil supply which decrease occurs in higher engine speed, thus enabling the provision of an end bearing having superior anti-seizure characteristics.
