PROBLEM TO BE SOLVED: To provide a battery unit replacing device having a simple structure of hardly requiring to slide a battery unit relative to an electrically-driven carrier vehicle.SOLUTION: A battery unit replacing device makes a battery unit 30 transferable between an electrically-driven carrier vehicle and a battery dolly 11. The battery unit 30 includes a front engagement part and a rear engagement part engageable with the electrically-driven carrier vehicle in a battery storage part A. The electrically-driven carrier vehicle includes a depth side engagement part enabling engagement of the front engagement part at the depth side of the battery storage part A, and an opening side engagement part enabling engagement of the rear engagement part at the opening side. The battery unit 30 is inclined forward and backward in the battery storage part A through the battery dolly 11 so as to make the battery unit 30 transferable between the electrically-driven carrier vehicle and the battery dolly 11. |
