PROBLEM TO BE SOLVED: To provide a shock absorber capable of providing sufficient damping force in a low area of a sliding speed of a piston, and capable of flexible telescopic control in response to various states. SOLUTION: In this shock absorber control device, the piston 42 partitions a cylinder chamber 40a filled with a working liquid into a first chamber 40b and a second chamber 40c. The piston 42 is formed with a flow passage 50 for making the working fluid flowed in from a front liquid chamber flow out to a rear liquid chamber among the first chamber 40b and the second chamber 40c when sliding in the cylinder chamber 40a. A screw 52 is arranged in the flow passage 50. A motor 20 drives the screw 52. An ECU 30 controls driving of the screw 52 by the motor 20. COPYRIGHT: (C)2009,JPO&INPIT |
