A scroll compressor, comprising: a first scroll provided with a fixed disk portion and a fixed wrap formed on a first surface of the fixed disk portion; a second scroll provided with an orbiting disk portion, an orbiting wrap formed on a first surface of the orbiting disk portion and engaged with the fixed wrap to form compression chambers, and a boss portion protruding from a second surface of the orbiting disk portion; a rotating shaft provided with an eccentric portion to transfer a rotational force; a frame having a shaft hole through which the rotating shaft is inserted, and supporting the second scroll in an axial direction; a first bearing provided between the shaft hole of the frame and an outer circumferential surface of the rotating shaft; and a second bearing provided between an inner circumferential surface of the boss portion and an outer circumferential surface of the eccentric portion of the rotating shaft, wherein the eccentric portion is inserted into the boss portion, and characterized in that the rotating shaft and the boss portion define a differential pressure space portion disposed radially between the first bearing and the second bearing, and in that the differential pressure space portion is formed in a manner of at least partially overlapping the first bearing and the second bearing in an axial direction of the scroll compressor, and in that a width of the differential pressure space portion in the radial direction is greater than a radial gap between an inner circumferential surface of the second bearing and the outer circumferential surface of the eccentric portion. a first scroll provided with a fixed disk portion and a fixed wrap formed on a first surface of the fixed disk portion; a second scroll provided with an orbiting disk portion, an orbiting wrap formed on a first surface of the orbiting disk portion and engaged with the fixed wrap to form compression chambers, and a boss portion protruding from a second surface of the orbiting disk portion; a rotating shaft provided with an eccentric portion to transfer a rotational force; a frame having a shaft hole through which the rotating shaft is inserted, and supporting the second scroll in an axial direction; a first bearing provided between the shaft hole of the frame and an outer circumferential surface of the rotating shaft; and a second bearing provided between an inner circumferential surface of the boss portion and an outer circumferential surface of the eccentric portion of the rotating shaft, wherein the eccentric portion is inserted into the boss portion, and characterized in that the rotating shaft and the boss portion define a differential pressure space portion disposed radially between the first bearing and the second bearing, and in that the differential pressure space portion is formed in a manner of at least partially overlapping the first bearing and the second bearing in an axial direction of the scroll compressor, and in that a width of the differential pressure space portion in the radial direction is greater than a radial gap between an inner circumferential surface of the second bearing and the outer circumferential surface of the eccentric portion.
