This invention discloses an eccentric sleeve and a scroll compressor. The eccentric sleeve includes a shaft portion and an edge portion. The edge portion includes a front end edge and a rear end edge disposed radially on the shaft portion. The edge portion is formed by the front end edge extending around the edge of the shaft portion towards the rear end edge. The front end edge and / or the rear end edge are at least partially tangential. By implementing this invention, the front end edge and rear end edge are designed with tangential structures. When the eccentric sleeve rotates, the tangential structures of the front end edge and rear end edge cause them to be tangential to the refrigerant oil. The small contact area between the front end edge and the refrigerant oil greatly reduces the agitation of the refrigerant oil, reduces the generation of eddies, lowers the compressor's power consumption, and thus improves the compressor's energy efficiency.
