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 . <EOS>
