Abstract
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.
