Claims

[Scope of utility model registration request]

A casing that houses therein a pair of gears that transfer fluid sucked from a suction channel to a discharge channel and a rotating shaft that rotates integrally with these gears, and an end face of the casing in the axial direction of the rotating shaft is closed. In the gear pump equipped with a wall member, a recess is formed on the outer surface of the casing, a reinforcing rib integrally cast with the casing is provided to partition the inside of the recess, and a reinforcing rib that covers the recess and has an inner surface on the outer end surface of the reinforcing rib. A gear pump in which a heat medium jacket is formed by the panel in contact with the recess and the recess.
