To provide a travel area registration system for a work vehicle, which facilitates arrangement of a work vehicle capable of autonomously traveling at a travel start position.SOLUTION: A travel area includes: a first area including a work path where work is performed by a work machine； a second area which is set around the first area； and a travel start permitted area which is set within the second area. In a travel area stored in a storage part, a control part performs control so that a vehicle body part can autonomously travel along a path generated by a path generation part while detecting a current position of the vehicle body part by a position detection part, and in the second area, when an instruction for staring the work by the work machine is given, the control part determines whether or not the current position of the vehicle body part is present in the travel start permitted area, and when determining that the position is present in the travel start permitted area, the control part makes the vehicle body part autonomously travel from the current position to a start point of the work path and then makes the work machine starts the work.SELECTED DRAWING: Figure 11【課題】自律走行可能な作業車両の走行開始位置への配置が容易となる作業車両の走行領域登録システムを提供する。【解決手段】走行領域は、作業機により作業が行われる作業経路を含む第１の領域と、第１の領域の周囲に設定される第２の領域と、第２の領域内に設定された走行開始許可領域を含み、制御部は、記憶部に記憶された走行領域において、位置検出部により車体部の現在位置を検出しつつ、経路生成部によって生成した経路に沿って車体部を自律走行可能に制御するとともに、第２の領域において、作業機による作業の開始が指示された場合に、車体部の現在位置が走行開始許可領域にあるか否かを判定し、走行開始許可領域内であると判定された場合に、車体部を現在位置から作業経路の開始地点まで自律走行させた後、前記作業機による作業を開始させる。【選択図】図１１
