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.

Abstract: A cover is provided with a connection portion on an outer peripheral portion for conducting fastening. The connection portion is provided with a fastening face that is fastened by a bolt on a top face and a connecting face that is connected to the base on a bottom face, and the connection portion is formed into a stepped shape with steps that form a recessed shape on the top face and a projected shape on the bottom face with respect to the outer peripheral portion. The steps are set to have dimensions less than a thickness of a plate material. The stepped shape is provided with an outer face of the step and an inner face of the step that do not overlap each other in a planer direction of the connecting face.
