PURPOSE: A bearing arrangement of a swash plate type compressor is provided in which a top portion of a shoe and a spherical seat of a piston are separated from each other to avoid a contact therebetween while an appropriate contact area of the shoe is ensured even when an angle of inclination of the swash plate increases, to thereby achieve an enhanced lubrication. CONSTITUTION: A bearing arrangement comprises a spherical seat(4b) made up of a single concavity formed at a piston(4), and a sphere-like shoe(10) contacting the spherical seat(4b), wherein the shoe further has an outer peripheral surface composed of a skirt portion(12), a top portion(16) having a radius of curvature larger than that of the spherical seat(4b), and a transitive portion(14) arranged between the skirt portion(12) and the top portion(16) and which has a radius of curvature smaller than that of the spherical seat(4b), the transitive portion(14) being in contact with the spherical seat(4b).
