Claim 0:
1. An article transport apparatus comprising a transfer apparatus that moves an article in a transfer direction, and a movement apparatus that moves the transfer apparatus along a transport path, wherein:
a direction orthogonal to the transfer direction when viewed in a vertical direction is defined as a width direction,
the transfer apparatus is provided with a first protruding/retracting unit capable of protruding/retracting in the transfer direction, and a second protruding/retracting unit capable of protruding/retracting in the transfer direction and installed in a state spaced apart from the first protruding/retracting unit in the direction,
the transfer apparatus further comprises a first drive unit that moves the first protruding/retracting unit in the width direction, and a second drive unit that moves the second protruding/retracting unit in the width direction,
the first drive unit is provided with a first connection unit connected to the first protruding/retracting unit, a swing mechanism that swings the first connection unit around a prescribed axis, and a first drive mechanism that drives the swing mechanism, the first drive unit configured to move the first protruding/retracting unit in the width direction within a first setting range by swinging the first connection unit,
the second drive unit is provided with a second connection unit connected to the second protruding/retracting unit, a reciprocating movement mechanism that moves the second connection unit in a reciprocating manner along a prescribed path in the width direction, and a second drive mechanism that drives the reciprocating movement mechanism, the second drive unit configured to move the second protruding/retracting unit in the width direction within a second setting range wider than the first setting range by moving the second connection unit back and forth in the prescribed path,
the swing mechanism is provided with a swinging body supported so as to be capable of swinging around the prescribed axis, and
the first connection unit is provided with a first connection body provided at a position away from the prescribed axis in the swinging body, and a guide unit that is provided in the first protruding/retracting unit and slidably guides the first connection body in a direction that intersects the width direction.
