PROBLEM TO BE SOLVED: To provide a front folk which can easily adjust an attenuation force generated at an elongation-side stroke.SOLUTION: A front folk comprises: an outer tube; an inner tube; a cylinder arranged inside the outer tube; a piston which is slidable with the cylinder; a piston rod attached to the piston; a piston-side oil chamber and a rod-side oil chamber which are formed in the cylinder; a flow passage for making the rod-side oil chamber and the piston-side oil chamber communicate with each other; an attenuation valve which is arranged at the piston, opens the flow passage while separating from the piston when the hydraulic pressure of the flow passage reaches prescribed pressure, and generates an attenuation force corresponding to a flow of oil; and an attenuation force adjusting device for adjusting the opening/closing of the valve. The attenuation force adjusting device is extended from the vicinity of a lower end of the inner tube, and penetrates the piston and the attenuation valve, and the other end of the device can contact with the attenuation valve from an upper end side when the valve is separated.SELECTED DRAWING: Figure 2

    【課題】伸側行程時に発生する減衰力を容易に調整できるフロントフォークを提供する。【解決手段】フロントフォークは、アウタチューブと、インナチューブと、前記アウタチューブの内側に設けられるシリンダと、前記シリンダに摺動可能なピストンと、前記ピストンに取り付けられるピストンロッドと、前記シリンダ内に形成されたピストン側油室及びロッド側油室と、前記ロッド側油室と前記ピストン側油室とを連通する流路と、前記ピストンに設けられ、前記流路の油圧が所定圧力に達したときに離間して前記流路を開き、油の流れに応じた減衰力を発生する減衰バルブと、前記バルブの開閉を調整する減衰力調整装置とを備え、前記減衰力調整装置は、インナチューブの下端近傍から延設されて前記ピストン及び前記減衰バルブを貫通し、その他端が、前記バルブが離間した場合に上端側から前記減衰バルブと接触可能である。【選択図】図2
