PROBLEM TO BE SOLVED: To provide a reciprocating pump capable of improving assemblability.SOLUTION: A cylindrical resin bearing 10 is arranged between a crankshaft 6 and a connecting rod 7 in a reciprocating pump. The bearing 10 is divided into two or more divided bodies in the axial view, and one of the divided bodies is a large divided body 10a having a central angle larger than 180°. When assembling the crankshaft 6, the bearing 10 and the connecting rod 7, the large divided body 10a can be externally fitted while being prevented from coming off from the crankshaft 6, and the connecting rod 7 can be attached without pressing the bearing 10. |
