Abstract: A tolerance ring includes: a base formed of a strip-like member substantially wound around into a shape; a plurality of projections provided along a winding direction of the base so as to protrude from an outer peripheral surface of the base in a radial direction of the base orthogonal to the outer peripheral surface; at least one extended portion extending from at least one of edge end portions in a width direction of the base, the width direction extending orthogonally to the winding direction and the radial direction. The extended portion extends from a region that includes at least one of a plurality of straight lines passing through respective contact points disposed between a section of the base and a circumscribed circle that circumscribes the section and extend in parallel with the width direction.
