Claims

[Scope of utility model registration request]

In a water pressure test pump, a manual reciprocating pump 2 is attached to a water tank 1, the suction side thereof is communicated with the inside of the water tank 1, and a valve 3, a pressure gauge 5, etc. are connected to the discharge port side. 2, a cylinder 12 having an inlet port 9 and a discharge port 10, a piston 13 fitted into the cylinder 12 so as to be slidable in the axial direction, and a tip end side of the piston 13 inserted into the piston 13 so as to be slidable in the axial direction. A plunger 14 is prevented from coming off from the piston 13 and has a diameter smaller than that of the piston 13 whose base end side protrudes from the cylinder 12.
An elastic body 15 is interposed between the piston 13 and the cylinder 12 and presses and urges the piston 13 toward the distal end of the plunger 14, and an elastic body 15 is interlocked and connected to the plunger 14 to slide it in the axial direction. A water pressure test pump characterized by comprising an operating section 16.
