A packing door for a refuse truck which in its fully open position is located along the roof of the truck body remote from the refuse compartment opening so that the opening is unobstructed. The door is provided with a bearing on each side which are identical, being elongated and having arcuately shaped ends. A piston and cylinder mechanism is mounted on each side of the truck body with a piston rod coupled to each bearing by a link. When the door is actuated from its fully open position, the piston and cylinder mechanisms move the bearings in a straight path along a rectilinear guide surface to move the door in a corresponding straight path rearwardly of the body until it extends above the opening of the refuse compartment. At the end of the rectilinear guideway the bearings enter a rotary guideway which prevents further rectilinear movement but guides the bearings in a rotary movement. Because of their overcenter connections to the bearings, further actuation of the piston rods causes rotation of the bearings in their associated rotary guideways to produce a corresponding rotation of the door through the opening into the refuse compartment for packing the refuse contained therein. Opposite actuation of the piston and cylinder mechanisms produces a reverse movement of the door for opening the compartment.
