A gripping mechanism which grips an object includes a main body section, a first gripping section, and a second gripping section. The first and second gripping sections are connected, with a space therebetween, to the main body section. The first gripping section includes a first roller and a first frame. The first frame houses the first roller. The first gripping section grips a first portion of an object between an outer surface of the first roller and an inner surface of the first frame using gravity acting on the first roller. The second gripping section includes a second roller and a second frame. The second frame houses the second roller. The second gripping section grips a second portion of the object, differing from the first portion, between an outer surface of the second roller and an inner surface of the second frame using gravity acting on the second roller.
