設けたことを特徴とするフロントフオーク。 A bottom case, a fork pipe that is slidable within the bottom case, a seat pipe that is fixed to the bottom of the bottom case and has a piston at its upper end that is slidable relative to the inner surface of the fork pipe, and the upper end of the piston and the fork pipe. A check valve and a blow valve whose orifice is biased to close by a spring are installed in an oil passage provided on the side of the bottom case. In the front fork of a motorcycle equipped with a compression-side damping force generation mechanism, the spring that biases the blow valve is composed of a relatively strong spring, and a relatively weak spring is connected in series with a spring seat sandwiched between this strong spring. A front fork further comprising: a check valve arranged movably in the axial direction; and a stopper for the check valve provided at a distance from the check valve.
