A coiled wave spring includes a first and second coiled portions. The first coiled portion has a plurality of first valley parts and a plurality of first peak parts. The first valley parts and the first peak parts are alternately disposed in a circumferential direction. The second coiled portion has a plurality of second peak parts and a plurality of second valley parts. The second peak parts respectively correspond to the first valley parts, whereas the second valley parts respectively correspond to the first peak parts. The second coiled portion extends continuously from the first coiled portion. The first peak parts are disposed away from the corresponding second valley parts at an interval in an axial direction. The first valley parts contact the corresponding second peak parts. Apices of the first valley parts are shifted from apices of the corresponding second peak parts in the circumferential direction.
