AbrégéProvided is a compressor, for example, having high performance and reliability. A compressor (100) comprises an upper bearing (5c) and a lower bearing (5d) of which at least one is provided with an oil pocket (h10) in a surface facing a cylinder chamber. When the rotational angle of a roller (5b) positioned at the top dead center in a cylinder (5a) is 0°, in a state in which the rotational angle of the roller (5b) is 0°, the oil pocket (h10) is positioned on the radially inner side of the roller (5b). In a state in which the rotational angle of the roller (5b) is 180°, the oil pocket (h10) is positioned between the roller (5b) and the cylinder (5a).
