<p><P>PROBLEM TO BE SOLVED: To provide a shock absorber in which an inexpensive and small solenoid can be used and a damping force can be actively controlled. <P>SOLUTION: The shock absorber includes: a shock absorber body D which includes a cylinder, a piston slidably inserted in the cylinder and partitioning the inside of the cylinder 2 into a compression-side chamber filled with liquid and an elongation-side chamber, and a piston rod 4 inserted in the cylinder and connected to the piston, and is placed between the vehicle body and the axle of a saddle riding type vehicle; a flow passage 5 making the liquid pass through during either the elongation or compression period of the shock absorber body D or both the periods; and a damping force control mechanism V which is disposed in the middle of the flow passage 5 and controls the damping force generated by the shock absorber body. The damping force control mechanism V includes a spool valve 7 and the solenoid 8, and the spool valve 7 includes a spool valve body 21 and a magnetic member 22 integrated with the spool valve body 21 and acting as the movable iron core of the solenoid 8. The specific gravity of the spool valve body 21 is controlled to be smaller than that of the magnetic member 22. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
