Abstract: A piston of a magnetic rheological fluid shock absorber comprises a piston core that is formed from a magnetic material and is provided with a coil on the outer periphery thereof, and a ring body that is formed from a magnetic material, surrounds the outer periphery of the piston core. A flow path of the magnetic rheological fluid is formed between the ring body and the piston core. The flow path of the magnetic rheological fluid comprises a first flow path part having a predetermined cross-sectional flow area, and a second flow path part having a larger cross-sectional flow area than the predetermined cross-sectional flow area and a longer axial length than the coil to cover the outer periphery of the coil.
