PURPOSE: A length-adjustable fodder feed pipe of a fodder vehicle is provided to reduce a worker's burden to a position adjustment problem of the vehicle by enabling length variation of a main feed pipe. CONSTITUTION: A length-adjustable fodder feed pipe of a fodder vehicle is installed to the upper part of a storage tank(100), to release fodder in the storage tank to a standoff place. The fodder feed pipe comprises a fixed pipe(12a) having a driving screw rotating by a hydraulic motor, and a variable pipe(12b) fitted to the end of the fixed pipe in the longitudinal direction. One end of the variable pipe is connected by a hydraulic cylinder(34) connected to the fixed pipe and a fodder discharge port is arranged to the front end of the variable pipe.
