A connector connects a rotatable body including an attachment hole and an engaging groove, and a shaft pressed into the attachment hole to integrally rotate. The connector includes at least one pin configured to fit in the engaging groove; and a screw having a head configured to be pressed against the rotatable body either directly or via another member. The at least one pin is fixed on the shaft and extends in a radial direction of the shaft to penetrate the shaft. The screw is screwed into a screw hole on an end face of the shaft and is tightened to press the at least one pin against a surface of the engaging groove.
