    摘要: Provided is a reciprocating compressor having a structure in which friction losses between a shaft and a bearing can be reduced without impairing the ability of the bearing to support the shaft. A reciprocating compressor (100) includes a cylinder (5), a piston (4), a connecting rod (6), a shaft (1), and a bearing (2). The shaft (1) has a journal portion (28) as a portion covered by the bearing (2). The journal portion (28) has a first journal portion (7) located closer to the connecting rod (6) with respect to a midpoint M of the journal portion (28) in a direction parallel to a rotational axis and a second journal portion (8) located farther from the connecting rod (6) with respect to the midpoint M. The bearing (2) has a first sliding portion (10) for supporting the first journal portion (7) and a second sliding portion (11) for supporting the second journal portion (8). The first sliding portion (10) has a first recessed portion (29) in at least one range selected from a range of 0° to 180° and a range of 270° to 360° in a rotational direction of the shaft (1) from a reference position.
