フトにおけるリフトシリンダの緩衝装；　　置。A spool fitted to the bottom of the shift cylinder so as to be movable up and down on the valve body is configured to control the flow rate of pressure oil by changing the cross-sectional area of the communication passage connecting the cylinder chamber and the supply/discharge port. In a forklift truck incorporating a flow control valve, a cylindrical hollow part formed at the lower end of the piston rod that can come into contact with the bottom surface of the lift cylinder is configured to allow the spool to move downward when the piston rod approaches the lowering end. A shock absorbing device for a lift cylinder in a forklift, characterized in that a spool pressing member for gradually narrowing a communication path is provided so as to be able to come into contact with the spool.
