发明名称 Dust cover
摘要 A dust cover made of resin comprising a bellows tube portion and a mating tube portion provided to one axial side of the bellows tube portion. The mating tube portion includes: a circumferential groove that opens onto an inner peripheral surface of the mating tube portion and is configured to receive a catch claw that projects from a cylinder to an outer peripheral side to be inserted into the circumferential groove from an opening of the mating tube portion; and at least one bent portion that has a mountain-shaped cross section projecting to the outer peripheral side while opening to an inner peripheral side of the mating tube portion and extends in an axial direction so that the mating tube portion is substantially enlarged in diameter via elastic deformation of the bent portion to expand in a circumferential direction.

主权项 1. A dust cover made of resin comprising a bellows tube portion having peaks and valleys arranged in a linked manner, the bellows tube portion being configured to externally fit onto a piston rod of a shock absorber that constitutes a suspension mechanism, and a first axial side of the bellows tube portion being configured to attach to the piston rod while a second axial side thereof being configured to attach to a cylinder of the shock absorber, wherein a mating tube portion is provided to the second axial side of the bellows tube portion, and the mating tube portion includes: a circumferential groove that opens onto an inner peripheral surface of the mating tube portion and is configured to receive a catch claw that projects from the cylinder to an outer peripheral side to be inserted into the circumferential groove from an opening of the mating tube portion; and at least one bent portion that has a mountain-shaped cross section projecting to the outer peripheral side while opening to an inner peripheral side of the mating tube portion and extends in an axial direction so that the mating tube portion is substantially enlarged in diameter via elastic deformation of the bent portion to expand in a circumferential direction, the at least one bent portion comprises a plurality of the bent portions that are separated from one another in the circumferential direction of the mating tube portion, and the circumferential groove extends between an interior peripheral surface of consecutive bent portions.
