ーク。 A wheel-side tube is slidably inserted into the vehicle-side tube, a hollow rod is movably inserted into the wheel-side tube via a piston, and the upper part of the hollow rod is connected to the vehicle-side tube. An oil lock case and a valve housing are provided in the middle of the inner periphery. Inside the valve housing, a valve guided to the outer periphery of a hollow rod is arranged so as to be able to move up and down. The oil chamber partitioned between the piston and the valve is inside the hollow rod. It communicates with the oil chamber inside the hollow rod through the provided expansion orifice, and an oil lock piece facing the oil lock case is installed on the upper outer periphery of the hollow rod, and the oil chamber provided above the valve is formed in the hollow rod. A front fork that communicates with an oil chamber inside a hollow rod through a pressure orifice, and is separated from a gas chamber through a partition wall provided on the inner periphery of the upper part of the hollow rod.
