PURPOSE: A trochoid gear pump is provided to increase amount of working fluid introduced and discharged. CONSTITUTION: A pump includes a driving shaft(14) receiving outside power and axially rotates; a driving gear(15) having the driving shaft fixed to a rotary center thereof in such a manner that the driving shaft penetrates the rotary center thereof, and having a plurality trochoidal gear teeth formed on a periphery thereof; a first slave gear(17) having the driving gear eccentrically stored therein in such a manner that the first slave gear is driven as the driving gear rotates, having a plurality of trochoidal gear teeth formed on an inner circumferential surface thereof to be engaged with the driving gear and pushed by the trochoidal gear teeth of the driving gear as the driving gear rotates so as to receive rotary torque in number larger than number of the teeth of the driving gear by one, and having trochoidal gear teeth formed on a periphery thereof in number identical with the number of the teeth formed on the inner circumferential surface thereof; a second slave gear(19) having the first slave gear eccentrically stored therein in such a manner than the second slave gear is driven as the first slave gear rotates, having a plurality of trochoidal gear teeth formed on an inner circumferential surface thereof to be pushed by the teeth formed on the periphery of the first slave gear so as to receive rotary torque, in number larger than the number of teeth of the first slave gear by one.
