Abstract
A coiled wave spring used by a diaphragm damper device and arranged in a fuel chamber defined by a housing and a cover is provided. The coiled wave spring is configured to be arranged between a diaphragm damper of the diaphragm damper device and the cover. The coiled wave spring is configured to fix the diaphragm damper to the housing with its elastic force. The coiled wave spring includes a coil portion, a winding initiation portion, and a winding termination portion. The winding initiation portion and the winding termination portion form flat seat windings. The seat windings each have a larger outer diameter than the coil portion. One of the seat windings is configured to be fixed to the diaphragm damper.
