PROBLEM TO BE SOLVED: To place switches for telescopically moving a mobile carrier pipe so as to easily be operated by constituting a grain-discharging auger with a fixed carrier pipe and the mobile carrier pipe which can lengthwise move. SOLUTION: In a combine harvester where a traveling chassis 8 having a running gear 8a is mounted with a grain tank 1 transiently storing grains, a grain elevating tube 12 unloading grains transiently stored in the tank 1 and an auger 14 carrying out grains, the auger 14 comprises a fixed carrier pipe 15 and a mobile carrier pipe 2 lengthwise moving telescopically in an interfitted state with the pipe 15. When an extension switch 31 for extending the pipe 2 and a contraction switch 32 for retracting the pipe 2 are installed at the rear of a final control element 30, this telescopic auger equipment is characterized by installing the extension switch 31 at the left side and the contraction switch 32 at the right side in being viewed from the final control element 30 backward.
