## Abstract

A transport vehicle includes: a traveler; a transferer that is mounted on the traveler and receives or delivers an article from or to a transfer destination; and an antenna that is provided so that at least the position or the posture thereof can be changed to follow the action of the transferer, and that performs wireless communication with another device.

## Claims

### Claim 1

A transport vehicle comprising:
a traveler;
a transferer mounted on the traveler and receives or delivers an article from or to a transfer destination;
an antenna provided so that at least the position or the posture thereof can be changed to follow action of the transferer, and that performs wireless communication with another device; and
a rotation driver that rotates the transferer around a vertical axis, wherein
the position of the antenna around the vertical axis is changed to follow the rotation of the transferer by the rotation driver, wherein
the transferer includes a lateral mechanism that causes a holder for holding an article to move horizontally,
the rotation driver causes the lateral mechanism to rotate around the vertical axis, and
the antenna is provided in a portion of the transferer other than the portion that is moved horizontally by the lateral mechanism.

### Claim 2 (depends on 1)

The transport vehicle according to claim 1, further comprising:
a frame that surrounds the transferer and is rotated around the vertical axis together with the transferer by the rotation driver, wherein
the antenna is mounted on the frame.

### Claim 3

A transport vehicle comprising:
a traveler;
a transferer mounted on the traveler and receives or delivers an article from or to a transfer destination;
an antenna provided so that at least the position or the posture thereof can be changed to follow action of the transferer, and that performs wireless communication with another device; and
a rotation driver that rotates the transferer around a vertical axis, wherein
the position of the antenna around the vertical axis is changed to follow the rotation of the transferer by the rotation driver, and
a frame that surrounds the transferer and is rotated around the vertical axis together with the transferer by the rotation driver, wherein
the antenna is mounted on the frame.

### Claim 4 (depends on 3)

The transport vehicle according to claim 3, wherein the antenna is mounted in a state of projecting downward from a lower end of the frame.

### Claim 5

A transport vehicle comprising:
a traveler;
a transferer mounted on the traveler and receives or delivers an article from or to a transfer destination; and
an antenna provided so that at least the position or the posture thereof can be changed to follow action of the transferer, and that performs wireless communication with another device , wherein the traveler travels on a grid-patterned track, proceeds to a cell if a procession permission corresponding to each of the cells of the grid of the track is granted by communicating with the another device via the antenna, and does not proceed to the cell if the procession permission is not granted.
