Abstract
A first plate portion covers one opening of a pump chamber of a tubular portion, and a second plate portion covers the other opening of the pump chamber along a center axis of the tubular portion. A hole forming portion is equipped to an outside of the tubular portion to form a connection hole. A length of the hole forming portion along the center axis is less than or equal to a length of the tubular portion along the center axis. A first imaginary line connects a center of an outer opening of the connection hole with a point on the center axis. The first imaginary line intersects perpendicularly with the center axis. A length of the connection hole in a direction perpendicular to both the first imaginary line and the center axis is greater than a length of the connection hole along the center axis.
