• the pump housing includes a suction port provided in an extending direction of the shaft, and a discharge port provided at one side of the impeller and in a direction crossing an extending direction of the shaft,
• the shaft includes an exposed portion at a tip end side further than a portion to which the cap is attached in the tip end portion, and
