Claims

[Scope of utility model registration request]

A spring 20 that biases the valve body 18 toward the closing side is received at the end of the valve shaft 17 extending from the valve body 18 of the check valve 13, 14 provided at the suction or discharge part of the reciprocating pump. This is a spring receiving member mounting structure for a check valve in which a spring receiving member 19 for stopping is attached, and a head 21 having a larger diameter than the valve shaft 17 is provided at the end of the valve shaft 17, and the head 21 can pass through. large diameter hole 22
a and a small diameter hole 22b which is smaller in diameter than the head 21 and larger than the valve stem 17, is formed in the spring receiving member 19, and the head is formed on the outer peripheral edge of the small diameter hole 22b. A structure for mounting a spring receiving member of a check valve in which a recessed stepped portion 23 is formed into which a portion 21 is depressed and held.
