Abstract:
An overhead transport vehicle includes: a traveler; a main body; a transferer including a holder, a mover, and a rotator, and which receives or delivers an article from or to a transfer destination; and a controller. The main body has an inner wall at a position at which the article held by the holder comes in contact therewith when the holder set at a storing position is rotated by a predetermined angle by the rotator. The controller causes the traveler to travel while the holder is at the storing position, and when the article is received or delivered, causes the rotator to rotate the holder by a predetermined angle or more about a rotation axis in a state where the holder is set at an exiting position by the mover to align the article with a prescribed orientation of the transfer destination.
