A compressor is configured such that an oil discharge channel (71c, 72c, 73c) that has a planar or concave shape and that communicates with an oil supply hole (71a, 72a, 73a) is formed in a drive shaft (23) so as to have a width less than or equal to the outer diameter of the oil supply hole (71a, 72a, 73a) and the edge on the rotationally trailing side of the drive shaft (23) in the oil discharge channel (71c, 72c, 73c) is displaced further in the direction of the rotationally trailing side of the drive shaft (23) than the edge on the rotationally trailing side of the drive shaft (23) in the oil supply hole (71a, 72a, 73a). Thus, foreign matter is prevented from accumulating in the oil supply hole (71a, 72a, 73a) of the drive shaft (23) of the compressor and a shaft bearing (29a, 29b, 29c) is prevented from being damaged. |
