Claims

[Scope of Claim for Utility Model Registration] (1) A pump shaft consisting of an impeller shaft portion to which an impeller is fixed and a power transmission shaft portion is provided inside the casing, and a convex transmission coupling portion consisting of a convex piece and a concave groove is provided. A shaped piece is formed on the shaft end side surface of one of the opposing impeller shaft portion and the power transmission shaft portion of the pump shaft, a concave groove is formed on the other side, a convex piece is spaced in the concave groove, and the convex piece is spaced apart from the concave groove. A water pump characterized by being rotatably connected to each other in the same direction in a universal joint at separate locations. (2) A pump shaft consisting of an impeller shaft to which the impeller is fixed and a power transmission shaft is provided inside the casing, and the convex piece of the transmission connection part consisting of a convex piece and a concave groove is placed opposite to the pump shaft. A concave groove is formed on the side surface of either one of the shaft ends of the impeller shaft portion and the power transmission shaft portion, and a convex piece is spaced apart from the concave groove, and the convex pieces are spaced apart from each other in the shape of a universal joint. A shaft support rod that is rotatably connected in the same direction and protrudes outward from the impeller side of the impeller shaft is pivotally supported in a shaft support hole of a bearing portion formed in the suction portion of the volute chamber. water pump.
