Abstract
A tolerance ring includes a ring body formed of a strip plate material having a spring property and formed in a ring shape. The tolerance also has a plurality of protrusions. The protrusions are formed on the ring body and radially protrude from the ring body. An abutment joint portion is formed between a first end and a second end of the ring body in the circumferential direction. The tolerance ring includes an insertion restricting portion configured to restrict an entering amount of another tolerance ring in the axial direction being inserted into the abutment joint portion from the side of the first edge of the ring body. The insertion restricting portion is located in an area between a first axial end of the plurality of the protrusions in the axial direction and the first edge, so as to restrict the entering amount of the other tolerance ring.
