<p>PROBLEM TO BE SOLVED: To provide a damper capable of changing an attraction force and a repulsion force which an additive agent receives from a surface of a sliding portion.SOLUTION: A damper D includes a cylinder 1, a piston rod 2 coming in and out with respect to the cylinder 1, a piston 3 held by the piston rod 2 and slidably kept into contact with an inner peripheral face 1a of the cylinder 1, a one-side chamber 10 and the other-side chamber 11 formed within the cylinder 1 and defined by the piston 3 in the cylinder 1, and a working fluid which is charged into the one-side chamber 10 and the other-side chamber 11 and to which an additive agent is added. It further includes a coil 4 wound on an outer periphery of the cylinder 1, and a magnet 5 mounted on the piston 3 or the piston rod 2 and disposed so that an S pole and an N pole are axially arranged. An electric circuit E is configured to include the cylinder 1 and the coil 4.</p> |
