Abstract
A coupling structure of an eccentric bush of a scroll compressor, comprising: an orbiting scroll; a rotary shaft provided with an eccentric part and transferring rotary power of a driving motor to the orbiting scroll; and an eccentric bush coupled between the orbiting scroll and the eccentric part of the rotary shaft, wherein an insertion hole provided with two plane contact portions having predetermined areas is formed at the eccentric bush, a cutting surface surface-contacting the plane contact portions of the eccentric bush is formed at the eccentric part of the rotary shaft, and the eccentric part is inserted into the insertion hole of the eccentric bush. Accordingly, damage to the eccentric bush or the rotary shaft can be prevented by dispersing the power applied to the rotary shaft and the eccentric bush.
