To provide a multiple gear pump which has not strict restrictions on mounting it on various liquid pressure machines by suppressing increase of length of a pump main body in a connection direction.
As an input side 14a of a driving shaft 14 in a first gear pump 11 and a driving motor are connected, an output side 14b of the driving shaft 14, an input side 15a of the driving shaft 15 in a second gear pump 12 are connected by a joint 17 and an output shaft 19b of a driven shaft 19 in the first gear pump 11 and an input shaft 16a of a driving shaft 16 in a third gear pump 13 are connected by a joint 18, driving torque from the driving motor is transmitted from the output shaft 14b of the driving shaft 14 in the first gear pump 11 to the input shaft 15a of the driving shaft 15 in the second gear pump 12 and transmitted from the output side 19b of the driven shaft 19 in the first gear pump 11 to the input side 19a of the driving shaft 16 in the third gear pump 13.
