<P>PROBLEM TO BE SOLVED: To provide a reciprocating pump improved in durability. <P>SOLUTION: A reciprocating member 1 is stably supported by two parts which are a collar 6 and a guide part 28. The collar 6 supports the reciprocating member 1 by a reduced diameter part 61 projected in a curve toward the axis side. An aligning function that can support the reciprocating member 1 slidably is thereby exhibited even when a deviation or an inclination arises in the axis direction of the collar 6 and in the axis direction of the guide part 28. As the inner diameter of the guide part 28, only the diameter of the reciprocating member 1 is therefore required to be considered without needing to consider an allowance in the case of the core of the collar 6 being shifted by the warp of a crankcase 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
