PURPOSE:To improve comfortability to ride, and make a shock absorber compact as a whole, by detecting a relative movement between an inner cylinder and an outer cylinder to adjust a damping force on occasion, and incorporating a control device and a driving motor, etc. in the shock absorber. CONSTITUTION:A magnetic sensor 11 for detecting a relative movement is embedded in one of an inner cylinder 2 and an outer cylinder 3, and a plurality of magnetic elements 12 are embedded in the other cylinder. The magnetic sensor 11 and the magnetic elements 12 constitute a stroke detecting means. There is provided between the inner cylinder 2 and a sheet pipe 4 mounted at the bottom of the outer cylinder 3 a damping force adjusting device 20 comprising a control device C, a driving motor M, a rod 21 connected at its one end to the driving motor M and adapted to be rotated thereby, and a damping rate adjusting valve 22 engaged with the rod 21. |
