A method of manufacturing a dust boot for a shock absorber, the shock absorber comprising:
- a cylinder;
- a rod configured to move into and out of the cylinder;
- a rod-side spring seat installed in the rod;
- a cylinder-side spring seat installed in the cylinder;
- a suspension spring interposed between the rod-side spring seat and the cylinder-side spring seat;
- and
- the dust boot,
- wherein the dust boot has
- a tubular boot body provided with an extendable/contractible bellows portion to cover the rod, and
- an annular flange portion linked to an upper end of the boot body and held between the rod-side spring seat and the suspension spring,
- wherein the shock absorber further comprises a rubber seat installed in an upper end of the suspension spring and interposed between the flange portion and the suspension spring, and
- wherein an angle between the flange portion and a line perpendicular to an axis of the boot body in an outer side of the flange portion is set to be larger than 0 degrees and smaller than 90 degrees,
- said method comprising:
- forming both the boot body and the flange portion through blow molding.
