a platform that is provided with a first transport portion that transports articles that are to be shipped, and a second transport portion that transports articles that have been received;

a berth that is provided along a platform edge of the platform to allow a transport vehicle to be parked side-on; and

a transfer device that moves back and forth between an intermediate transport area and a load bed adjacent area in the vehicle's widthwise direction to transfer an article between the platform and the transport vehicle, the intermediate transport area being located downstream of the first transport portion and upstream of the second transport portion, and the load bed adjacent area being adjacent to a load bed of the transport vehicle when the transport vehicle is parked on the berth,

wherein the transfer device includes a travelling portion that travels along a travel rail that is provided in the vehicle's widthwise direction,

wherein the transfer device includes: a supporting portion that supports, from below, the base pallet on which the articles are placed; a sliding portion that slides in the vehicle's widthwise direction relative to the supporting portion, in a state of being locked to the base pallet; and a lift portion that is provided for the travelling portion and raises and lowers the sliding portion and the supporting portion, and

wherein the lift portion is configured to move upward and downward to switch the height of a supporting surface of the supporting portion to a first height set depending on the height of supporting surfaces of the first transport portion and the second transport portion, and a second height set depending on the height of a supporting surface of the load bed of the transport vehicle.

2. The distribution facility according to claim 1 , wherein the transfer device passes and receives a plurality of articles that are placed on a single base pallet, all at once.

3. The distribution facility according to claim 1 , wherein the transfer device further includes a conveyor unit that is configured to transport the articles in a direction that is orthogonal to the vehicle's widthwise direction, and

wherein the conveyor unit is configured to move in a vertical direction relative to the supporting portion, and to protrude upward from the supporting surface of the supporting portion when the transfer device is located at a specific position in the intermediate transport area and the lift portion has moved downward to a lower limit position, and to be located below the supporting surface of the supporting portion when the transfer device is located at a position other than the specific position.

4. The distribution facility according to claim 1 , wherein the platform is provided as a pair of platforms that face each other with a travel path therebetween on which the transport vehicle travels, and

wherein the transfer device is configured to move back and forth in the vehicle's widthwise direction between the respective intermediate transport areas of the pair of platforms, and to transfer articles between either one of the platforms and a transport vehicle that is parked on the berth corresponding thereto.

5. The distribution facility according to claim 1 , wherein the platform in plan view has a shape with a rectangular cutout position,

the intermediate transport area is provided in an area of the cutout portion, and

the first transport portion and the second transport portion are provided to face the cutout portion.

6. The distribution facility according to claim 5 , wherein the first transport portion, the intermediate transport area and the second transport portion are aligned.

7. The distribution facility according to claim 1 , further comprising a berth forming deck protruding from the platform edge of the platform toward a travel path through which the transport vehicle travels,

wherein the berth is provided along a deck edge of the berth forming deck, and

the load bed adjacent area is provided in an area in which the berth forming deck is formed.

8. The distribution facility according to claim 1 , wherein the transport vehicle is a truck.

9. The distribution facility according to claim 8 , wherein the truck has a wing-type load bed, and the article is loaded and unloaded via an opening provided in a lateral side of the load bed, with the truck being parked on the berth.

10. The distribution facility according to claim 1 , wherein the sliding portion has a hook portion with a locking claw at an end of the hook portion, and the hook portion is rotatable about a shaft that extends in a vertical direction.

11. The distribution facility according to claim 10 , wherein the base pallet has: a lock-target portion to which the locking claw of the sliding portion is hooked; and a retracted portion which is formed at a position adjacent to the lock-target portion, for preventing interference with the locking claw.
