Abstract
The present invention relates to a method for manufacturing a sintered bearing having a bearing surface that forms a bearing gap with a shaft to be supported, in its inner periphery. This manufacturing method includes: a compacting step Pof compacting a base powder containing a diffusion alloyed powderprepared by partially diffusing a copper powder in an iron powder as a main material, a low-melting-point metal powder, and a solid lubricant to obtain a green compact, and a sintering step Pof sintering the green compact' to obtain a sintered compact
