Abstract: A bushing assembly having a self-alignment function includes inner bushings mounted in outer bushings. A center adjustment unit is mounted between the outer bushing and the inner bushing, and includes convex arcuate faces mating with concave arcuate faces. Thus, the inner bushing may micro-adjust an assembly angle automatically, to maintain at the same axis with other inner bushing, thereby facilitating passage and mounting of a shaft. In addition, the outer bushing or the inner bushing is formed with a slit, or the outer bushing may be made detachable, so that the outer bushing and the inner bushing may be combined easily.
