PROBLEM TO BE SOLVED: To obtain a motor lorry capable of ascending and descending stairs for reducing operator's fatigue. SOLUTION: The motor lorry is equipped with a front wheel 3, a rear wheel 7, a skid plate 2 extended from the near the front wheel 3 backward to obliquely upper side, a main link 4 which is connected with a frame 1 supporting the front wheel 3 and the skid plate 2, and extends from the rear part of the frame 1 to more obliquely upper side than the extending direction of the skid plate 2, an operating link 5 having a holding part 5a, a parallel link 6 capable of vertically moving the operating link 5 relative to the main link 4, and a rear wheel support link 8 and a rear wheel storage link 9 which interlocks with the movement of the parallel link 6 and vertically moves the rear wheel 7. The motor lorry moves the rear wheel 7 to the upper side than the extended surface of the bottom surface of the skid plate 2 interlocking with the movement to the upper side position of the operating link 5. The form change of the motor lorry 101 from a flat traveling state to the stair-traveling state can be easily performed. COPYRIGHT: (C)2005,JPO&NCIPI
