Document Type and Number:
WIPO Patent Application WO/2020/194903
Kind Code:
A1
Abstract:
A dust cover which ensures strength of a flange even when using a thermoplastic resin, a suspension device provided with a dust cover, and a dust cover manufacturing method are provided. This approximately cylindrical dust cover 6 comprises a thermoplastic resin formed by blow molding and covers the outside of a damper 3 that extends in a prescribed direction. The dust cover has a bellows section 61 which, in the axial direction, is inclined alternately outwards and inwards in the radial direction and which can expand and contract in the axial direction, and a flange 63 which extends radially outwards from a cylindrical section of the dust cover 6. The flange 63 protrudes from the cylindrical section of the dust cover 6 radially outwards higher than the radial height between the radial inner edge and the radial outer edge of the bellows section 61, and the thickness of the flange 63 is greater than the thickness of the radially outside edge of the bellows section 61.
