A damping force adjustable hydraulic shock absorber includes a piston rod projecting from a cylinder and an actuator for adjusting the level of damping force generated in the shock absorber, the actuator having a bottom portion and an axially extending outer peripheral portion. The shock absorber further includes a casing and retaining device. The casing has a bottom portion secured to the projecting end portion of a piston rod, a first rising portion which extends upward from the outer peripheral edge of the bottom portion, a flange portion which extends outward from the upper end of the rising portion and on which is placed the bottom portion of the actuator, and a second rising portion which extends upward from the outer edge of the flange portion, the second rising portion receiving at least a part of the outer peripheral portion of the actuator to prevent horizontal movement of the actuator. The retaining device retains the actuator on the flange portion of the casing while preventing upward movement thereof. Accordingly, it is possible to readily secure the actuator to the projecting end of the piston rod and it is also possible to minimize the space for accommodating the actuator and hence to lower the height of a vehicle or the like.
