PROBLEM TO BE SOLVED: To provide a rotation type compressor and a refrigeration cycle device, capable of ensuring operational reliability by suppressing one-side contact.SOLUTION: A rotation type compressor includes a cylinder and a bearing. The cylinder forms a cylinder chamber through which a rotational shaft 31 penetrates. The bearing blocks the cylinder chamber, and supports the rotational shaft in a rotatable manner. In the bearing, formed are annular grooves 81, 86 opened toward the inside of the cylinder chamber and extending in a circumferential direction. In at least part of the inner peripheral surface of the annular groove, a radial distance from the inner peripheral surface of the bearing is made nonlinearly larger toward the groove bottom part side of the annular groove. |
