<p>The purpose of the present invention is to provide a coiled wave spring capable of suppressing the diameter-directional expansion and a drag knob using the same. The coiled wave spring (9) comprises a first coiled portion (91a) and a second coiled portion (91b). The first coiled portion (91a) has a plurality of first valley parts (911a) and a plurality of first peak parts (912a), which are alternately disposed in a circumferential direction. The second coiled portion (91b) has a plurality of second peak parts (912b) corresponding to the first valley parts (911a) and a plurality of second valley parts (911b) corresponding to the first peak parts (912a). In addition, the second coiled portion (91b) continuously extends together with the first coiled portion (91a). The first peak parts (912a) are spaced apart from the corresponding second valley parts (911b) at an interval in an axial direction. The first valley parts (911a) are in contact with the corresponding second peak parts (912b). The apices (913a) of the first valley parts (911a) are away from the apices (914b) of the corresponding second peak parts (912b) in the circumferential direction.</p> |
