<P>PROBLEM TO BE SOLVED: To obtain high damping force while reducing an internal pressure of an oil chamber to improve ride quality of a vehicle, in a front fork. <P>SOLUTION: In the front fork 10, a piston rod 41 is suspended from the upper part inside an inner tube 12. In an upper piston 40 arranged in the piston rod 41, a pressure side flow passage 43A connected to a reservoir chamber 80 from the oil chamber 70 and a pressure side damping valve 43 opening/closing the pressure side passage 43A are arranged, while an extension side flow passage 44A connected to the oil chamber 70 from the reservoir chamber 80 and an extension side damping valve 44 opening/closing the extension side flow passage 44A are arranged. <P>COPYRIGHT: (C)2013,JPO&INPIT |
