Rotary connector

Abstract

This invention provides a rotary connector that reduces the generation of abrasive powder and inhibits its adhesion to current collectors. The rotary connector comprises: an annular conductive ring; a conductive shaft inserted into the conductive ring and configured to rotate relative to the conductive ring; a current collector disposed radially between the conductive ring and the conductive shaft; a retaining pin disposed between adjacent current collectors in the circumferential direction; and a retaining plate disposed on at least one axial side of the retaining pin, the retaining pin having a shaft portion that slides in contact with the retaining plate and a protrusion portion connected to one axial end of the shaft portion and extending outwardly beyond the shaft portion.
