PROBLEM TO BE SOLVED: To provide a tractor in which erroneous detection by an inertial measurement unit can be suppressed.SOLUTION: The tractor is provided with an inertial measurement unit 39 for measuring inertial data of a vehicle body 4, and right and left rear wheels 3 for driving the vehicle body. The inertial measurement unit 39 is provided at a position adjacent to a transmission case 10 for transmitting a driving force to the rear wheels 3 or a rigid member consisting a vehicle body frame 1.SELECTED DRAWING: Figure 44COPYRIGHT: (C)2019,JPO&INPIT【課題】慣性計測装置での誤検出の抑制が可能なトラクタを構成する。【解決手段】車体4の慣性情報を計測する慣性計測装置39と、走行用の左右の後輪3と、が備えられ、後輪3に駆動力を伝えるミッションケース10、あるいは、車体フレーム1で成る剛体部材に隣接する位置に慣性計測装置39を備えた。【選択図】図44
