PROBLEM TO BE SOLVED: To prevent a shift between swing angles of a pair of left/right swing arms, the shift being caused by a torsion of a drive shaft, to enable a large heavy load to be loaded/unloaded smoothly without tilting a bed to the left or right. SOLUTION: A vehicle has a lift 2 on the vehicle body upper surface 1A thereof. The lift 2 comprises the bed 3 which holds an article detachably, the drive shaft 7 which is rotated clockwise and counterclockwise by a drive source 6, and a pair of the left/right swing arms 9A, 9B each of which has one end fixed to the drive shaft 7 and the other end connected rotatably to one end of the bed 3, and is rocked vertically on the drive shaft 7. The drive shaft 7, which is connected to the drive source 6, is connected to a horizontal shaft 41 with a connecting metal piece 42 at one end side of the drive shaft 7, where the connecting metal piece 42 is so connected as to be incapable of rotating relative to the drive shaft 7.
