Abstract
A shock absorber is disclosed having an outer cylinder closed at one end thereof, a hollow inner cylinder closed at one end and opened at an another end thereof, the open end being inserted in the outer cylinder, a guide member for guiding the inner cylinder slidably in the outer cylinder, a member for generating a damping force, the damping force generating member being connected to the open end of the inner cylinder, and having an orifice for throttling flow of hydraulic fluid from a chamber in the outer cylinder to a chamber in the inner cylinder, the orifice being in a central portion of the inner cylinder, and a plate-like stop provided between the inner cylinder and the damping force generating member for retaining the damping force generating member against the damping force within a predetermined range, the stop having an aperture greater than the orifice.
