Beschreibung
Zusammenfassung:	A connection unit connected to a rotation body by fitting to transmit a rotation force includes a rotation shaft, having a width across flat portion; and a core member, having fitting portions fitted to the rotation body in a direction perpendicular to the width across flat portion and an annular portion that the width across flat portion are slidably fitted, and held on the rotation shaft to be capable of moving relatively in two dimensions along the width across flat portion while rotating integrally with the rotation shaft. Accordingly, generation of vibration or noise can be prevented, and easiness of assembly work, cost reduction, miniaturization and the like can be achieved.
