Abstract:
A damper includes a coil that generates a magnetic field acting on magneto-rheological fluid flowing through a communication passage. A piston includes a concave portion formed on an outer peripheral surface of a piston core, a regulating member housed in the concave portion, an introduction flow passage that guides the magneto-rheological fluid in a first fluid chamber or a second fluid chamber into the concave portion such that the regulating member projects into the communication passage, and a fail valve that opens and closes the introduction flow passage. In the case where a current applied to the coil is a predetermined value or less, the regulating member projects into the communication passage.

Claim (Index 1):
A magneto-rheological fluid damper that employs magneto-rheological fluid as working fluid, the magneto-rheological fluid changing viscosity in accordance with a strength of a magnetic field, the magneto-rheological fluid damper comprising:\n a cylinder into which the magneto-rheological fluid is sealed; a piston coupled to a piston rod, the piston being movably disposed in the cylinder; and a first fluid chamber and a second fluid chamber partitioned in the cylinder by the piston, wherein the piston includes:\n a piston core coupled to the piston rod; \n a ring body that surrounds an outer periphery of the piston core, a communication passage being formed between the piston core and the ring body, the communication passage communicating between the first fluid chamber and the second fluid chamber; \n an electromagnetic coil configured to generate a magnetic field acting on the magneto-rheological fluid flowing through the communication passage; \n a concave portion formed on an outer peripheral surface of the piston core; \n a regulating member housed in the concave portion; \n an introduction flow passage that guides the magneto-rheological fluid in the first fluid chamber or the second fluid chamber into the concave portion such that the regulating member projects into the communication passage; and \n a fail valve that opens and closes the introduction flow passage, wherein \n in a case where a current applied to the electromagnetic coil has a predetermined value or less, opening the introduction flow passage by the fail valve projects the regulating member into the communication passage.
