PROBLEM TO BE SOLVED: To provide a damping force adjustable damper to be able to reduce the size and weight, and to facilitate the manufacturing, etc., of a piston. SOLUTION: The piston 16 comprises an outer yoke 31 whose outer peripheral surface is slid with the inner wall of a cylinder 12, an inner yoke 32 arranged in the outer yoke 31, six gap spacers 33 interposed between the outer yoke 31 and the inner yoke 32, an MLV coil 34 externally fitted in the axial center of the inner yoke 32, and a thermosensitive shut-off valve 35 installed at the lower surface of the inner yoke 32 as main components. The inner yoke 32, which is made of a ferromagnetic material in the same way as the outer yoke 31, is also two-divided into a first inner yoke 41 to form the upper part, and a second yoke 42 to form the lower part, and fastened/incorporated by three screws 43, clamping the outer yoke 31 via the cap spacer 33.
