An automatically adjustable damping force shock absorber includes an outer cylinder; an inner cylinder provided in the outer cylinder; a piston inserted into the inner cylinder. The piston includes a plunger assembly slidably fitted in the inner cylinder so as to divide the inner cylinder into two compartments and provided with orifices on a side wall thereof, several one way valves on a upper and lower walls thereof and a cylindrical piston rod connected at one end thereof to the plunger assembly, a control valve provided in the plunger assembly for controlling fluid amount passing through the orifices and one way valves of the plunger assembly, and an electric power supplier connected to the control valve by a cable for supplying electric power. The electric power supplier includes an accelerometer for detecting extension and contraction of the shock absorber and responsively producing an acceleration level signal, an amplifier for amplifying the acceleration level signal, and a voltage generator for generating voltage on the basis of the acceleration signal.
