PROBLEM TO BE SOLVED: To provide a front fork capable of obtaining proper attenuation force irrespective of the running state at a braking time or a steady running time.SOLUTION: A ring-shaped outer buffer chamber M is formed on the outer circumference side of an oil flow passage chamber R, and a ring piston member 14, which is made of a cylindrical ring body 15 for sliding hermetically on the inner and outer circumferences of the outer buffer chamber M, is housed. Moreover, a sliding member 41 disposed in the lower part of said cylindrical ring body 15 is pushed toward a lower pressure chamber 17A so that the pressure chamber 17A is compressed to acquire reactive force. |
