Abstract

A dust cover receiving structure of a hydraulic shock absorber in which a seat rubber is interposed between a suspension spring and a spring seat. The seat rubber has a spring receiving portion which is arranged between the suspension spring and the spring seat, a centering portion which is fitted to a damper tube and guides an end portion of a dust cover in such a manner as to align the dust cover with an axial center of the damper tube, and a cover receiving portion which is provided between the spring receiving portion and the centering portion, and which receives an end surface of the dust cover.

Dependent claims

A dust cover receiving structure of a hydraulic shock absorber, said dust cover receiving structure comprising:

a dust cover places on a damper tube and having one end portion fixed to a side of a piston rod;
a suspension spring provided at an outer side of the dust cover and supported by a spring seat mounted on the damper tube;
and
a seat rubber interposed between the suspension spring and the spring seat,
wherein the seat rubber comprises:
a spring receiving portion which is arranged and clamped between the suspension spring and the spring seat,
a centering portion which is fitted to the damper tube and which guides another end portion of the dust cover so as to align the dust cover with an axial center of the damper tube, and
a cover receiving portion which is provided between the spring receiving portion and the centering portion and which receives an end surface of the dust cover at said another end portion of the dust cover;
and
wherein the end surface of said another end portion of the dust cover moves into contact with the cover receiving portion when the hydraulic shock absorber contracts, and moves out of contact with the cover receiving portion when the hydraulic shock absorber expands.
