A bearing device of a scroll compressor is provided to optimize loss of the bearing according to light or heavy load situations by generating elastic deformation in a small inner-diameter part through volume expansion/retraction. A bearing device of a scroll compressor includes a bearing(39) having an inner diameter part consisting of a small inner-diameter part(100) and a large inner-diameter part(101), wherein the small inner-diameter part is elastically deformable. A contact area between a rotation shaft and the small inner-diameter part varies according to the load applied to the compressor so that an area for supporting the rotation shaft increases as the load of the compressor increases and decreases as the load decreases. |
