〔Effect of the invention〕

According to this invention, the container support stand 2 in the transport vehicle 1
With wheels 7 attached to both sides of the container 6 in the width direction placed on a pair of container support rails 3 provided at The rail 3 is arranged in series with a pair of container running rails 5, and then the first transfer roller 10 provided on the container support base 2 is pressed against the transfer roller pressure contact horizontal surface 8 of the container 6, and the transfer is carried out. After rotating the first transfer roller 10 by the first driving device 9 to move the container 6 forward, the second transfer roller 13 provided on the support frame 11 is moved to the horizontal surface 8 for pressure contact of the transfer roller in the container 6. By repeatedly rotating the second transfer roller 13 by the second transfer drive device 12 in the pressed state and moving the containers 6 forward, a large number of containers 6 can be moved in series for container traveling. A large number of containers 6 can be sequentially transferred into the container storage chamber 4 along the rails 5, and therefore, two drive devices, the first drive device 9 and the second drive device 12, are used to transport a large number of containers 6.
, the number of drive devices used can be reduced, the operation control device for the drive devices can be simplified, and a device for transporting a large number of containers can be manufactured at low cost.
