Abstract
An apparatus for automatically assembling an inner rotor and an outer rotor substantially applied to an inscribe-type gear pump. Described is the construction and the function of the apparatus for incorporating inner rotors into outer rotors in such a manner that a holding pin which is pressed into a central hole of inner rotor descends together with the inner rotor until the accompanying inner rotor is filled into outer rotor. While the holding pin is lowered together with inner rotor, it is rotated so that gear portions of both rotors can be aligned properly and engage.
