Abstract
In order to highly precisely adjust a gap between a bearing and a gear rotor by a simple configuration, a gear pump of the present invention includes: a casing that includes an inlet and an outlet; a pair of gear rotors each of which is formed by integrating a gear portion with a shaft portion and which is disposed so as to engage with each other inside the casing; a bearing portion that supports the shaft portion so that the gear rotor is rotatable, the bearing portion being movable in the thrust direction of the gear rotor; and a gap adjustment unit that moves the bearing portion in the thrust direction so as to adjust a gap between the gear rotor and the bearing portion.
