Abstract:
A suspension apparatus includes: a cylinder (21) connected to one of a sprung member and an unsprung member, an interior space of the cylinder (21) being partitioned into a piston upper chamber (39) and a piston lower chamber (40); a piston (22) connected to the other of the sprung member and the unsprung member; an expansion side friction member (44) configured to damp a movement of the piston (22), a force of the expansion side friction member (44) for damping the movement of a piston (22) being increased by exerting a pressure of the piston upper chamber (39) on the expansion side friction member (44); and a contraction side friction member (45) configured to damp the movement of the piston (23), a force of the contraction side friction member (45) for damping the movement of the piston (22) being increased by exerting a pressure of the piston lower chamber (40) on the contraction side friction member (45).
