Abstract

A grounding structure includes a rotation shaft and a grounding member. The rotation shaft has a non-circular cross section, and rotates. The grounding member is attached to the rotation shaft to electrically communicate with the rotation shaft, and rotates together with the rotation shaft. The grounding member includes a first grounding portion, a grounding retainer and a second grounding portion. An outer shape of the first grounding portion is a circular shape. The grounding retainer is provided on a side of the first grounding portion in a shaft direction of the rotation shaft, and has an outside diameter being larger than an outside diameter of the first grounding portion. The second grounding portion is elastically held in contact with the first grounding portion.
