Abstract

A shock-absorber controlling apparatus is provided. A fluid passage (42a) is formed in a piston (42), and the piston moves in a cylinder (40) while causing the working fluid in a fluid chamber located before the piston (42) in the moving direction of the piston (42) to flow to the fluid passage (42a) and then to a fluid chamber located after the piston (42) in the moving direction. A first gear (50) and a second gear (52) are arranged to be rotated by the flow of the working fluid in the fluid passage (42a). A motor generator (19) generates electric power through the rotations of the first gear (50) and the second gear (52). Braking forces are applied to the first gear (50) and the second gear (52) by causing the electric current generated at the motor generator (19) to be supplied to a variable resistor (20). An ECU (30) controls the damping force on the piston (42) by changing the resistance of the variable resistor (20).
