ABSTRACT:
A fluid pump includes a case including a pump chamber, a reserve tank for storing spare liquid and located in the case but outside the pump chamber and formed so that a space independent of the pump chamber is defined by the reserve tank, a fluid path forming member arranged inside the reserve tank and including a discharge path communicating between a discharge port and the pump chamber, and a communication hole which is formed in a side of the fluid path forming member so as to assume such a position that the communication hole faces an inside of the reserve tank so that the hole communicates between the discharge path and the inside of the reserve tank, the communication hole being sized so that air in the pump chamber is allowed to flow through the hole into the reserve tank.
