ンプにおけるインナーローターと駆動軸との結合構造。[Scope of Claim for Utility Model Registration] ■ Connection between the inner rotor and the drive shaft in a trochoid pump in which an engagement projection is provided on the drive shaft and the engagement projection is fitted into an engagement groove provided in the shaft hole 5 of the inner rotor. In the structure, the number of retaining grooves provided in the shaft hole of the inner rotor is greater than the number of engaging protrusions provided in the drive shaft, and these engaging grooves are arranged circumferentially at intervals of 120 degrees or less. A coupling structure between an inner rotor and a drive shaft in a trochoid pump, characterized in that they are arranged substantially evenly in directions. ■ Practical technology in which the engagement grooves are arranged approximately evenly in the circumferential direction at an angle obtained by dividing 360° by a value of 3 or more selected from among the divisors of the number of teeth of the inner rotor. A coupling structure between an inner rotor and a drive shaft in a trochoidal pump according to claim 1. (2) The inner rotor in the trochoidal pump according to claim 1, wherein the number of the engagement grooves is equal to the number of teeth of the inner rotor, and the locking groove is provided at the crest of the teeth of the inner rotor. and the coupling structure between the drive shaft and the drive shaft.
