Abstract
An intermediate cylinder is disposed between an outer cylinder and an inner cylinder. The intermediate cylinder forms a passage between the inner cylinder and itself, through which a hydraulic fluid as an electrorheological fluid flows. The intermediate cylinder is supplied (applied) with a voltage through an electrode connector. The intermediate cylinder includes a ring member. The ring member is provided with an extending portion which extends toward the outer cylinder. The extending portion of the ring member is inserted with an electrode pin as an imparting unit for imparting a voltage to the intermediate cylinder.
