A tolerance ring includes a ring body having a spring property, an abutment joint portion formed between circumferential end edges of the ring body, and protrusions protruding radially from the ring body, each having a reaction force due to radial rigidity. The tolerance ring includes an abutment joint semi-circumferential region and an opposing semi-circumferential region facing the abutment joint portion. The tolerance ring includes first and second X-direction semi-circumferential regions separated by a straight line connecting the abutment joint and opposing portions. The Y-direction passes through the axis center of the ring body and the abutment joint, and the X-direction is orthogonal to the Y-direction. The sum of the X-direction components of the reaction force vector in the first X-direction semi-circumferential region is the same or smaller than the sum of the Y-direction components of the reaction force vector in the abutment joint semi-circumferential region.
