<p>A double tube hydraulic shock absorber comprises: an outer tube; an inner tube; a base valve which is fitted and fixed to a base end of the inner tube; a lower cap provided so as to contact a leg portion of the base valve and seal a base end of the outer tube in an oil tight fashion; a piston rod inserted into the inner tube so as to be capable of an axial reciprocation; and a guide member attached to a top side of the outer tube and the inner tube so as to support the piston rod and apply an axial force on the inner tube. In this double tube hydraulic shock absorber, the leg portion of the base valve and the lower cap contact each other on a line of action of the axial force that is applied toward the base end of the inner tube.</p> |
