摘要： Peripheral sections of two diaphragms are stacked on each other. The peripheral sections of the two diaphragms form an outer rim of a diaphragm damper. The outer rim is continuously sealed and joined by laser welding over the entire circumference of the outer rim. The thickness of the tip of the outer rim is set in correspondence with the spot diameter of a laser beam at the tip of the outer rim. A weld bead is formed by welding in the entire area of the tip of the outer rim.

摘要： A holding member for a diaphragm damper device including a plurality of diaphragm dampers is formed from an elastic member. The holding member includes a band that can be elastically tightened to circumferential walls of two adjacent ones of the diaphragm dampers and hooks arranged on two sides of the band. The hooks elastically hold each of the diaphragm dampers that are stacked.

摘要： 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.
