Claims

[Scope of utility model registration request]

In a reciprocating pump in which a piston is attached to the tip of a piston rod that is inserted into and removed from a cylinder, and the piston is reciprocated within the cylinder, a piston body is disposed at the tip of the piston rod, and the piston body and A piston for a reciprocating pump, wherein a packing means interposed between the cylinder and capable of reciprocating the piston body into the cylinder in a water-tight state is integrally attached to the piston body by baking or adhesion.
