PURPOSE:To set the stopping position by providing a recess in the inclined guide face and to enlarge the lift angle. CONSTITUTION:A guide section 1 is inclined by a frame body 6 to form a recess 3. When the rear wheel 2 of a trailer is positioned at the recess it is stopped, and lifted by a lifter together with the trailer. The stopping position is made clear by the recess while since the wheel will rotate to the B direction by the lift, the lift angle is enlarged. |
