摘要

The cup spring has a non-slotted resilient ring (2) that is provided on a radially inward tongue portion (3). The tongue portion is provided with a crank (5) which is used as an internal unit (4) of a cup spring portion (1). The crank is used as a false-assembling prevention element, such that the false assembling of the cup spring portion is avoided since the axial displacement of radially inner end of tongue portion for mounting the locking ring (7) is prevented.
