Abstract
A tolerance ring for a torque transmission device is arranged in an annular space between an inner shaft member and an outer shaft member. The tolerance ring has a ring-shaped portion and a plurality of protrusions. The ring-shaped portion has a cylindrical shape and is brought into contact with one of the shaft members. The plurality of protrusions undergo elastic deformation and are arranged in a peripheral direction. The ring-shaped portion has seat portions formed between the protrusions that are adjacent to each other in the peripheral direction. The plurality of protrusions include selected protrusions that have the same shape and that are situated at the same axial position and unselected protrusions other than the selected protrusions. The selected protrusions and the unselected protrusions differ from each other in axial position of center point in a length direction.
