Abstract: A transfer apparatus (7) includes a first protruding/retracting unit (21), a second protruding/retracting unit (22), and a control unit. The first protruding/retracting unit (21) includes a first arm (27A) that protrudes and retracts in a transfer direction, and a first hook (31) that swings around a first axis (P1). The second protruding/retracting unit (22) includes a second arm (27B) that protrudes and retracts in the transfer direction, and a second hook (32) that swings around a second axis (P2). A spacing changing unit is configured to change a spacing between the first arm (27A) and the second arm (27B) to a first spacing (D1) that is narrower than the sum of a first intermediate-state protrusion amount and a second intermediate-state protrusion amount and is wider than the sum of a first transferring-state protrusion amount and a second transferring-state protrusion amount.

Abstract: An article transfer device includes: a guide movement mechanism for moving a first guide portion and a second guide portion independently along a first direction; and an interlocking mechanism for interlocking movement of the first guide portion and the second guide portion along the first direction with movement of an article supporting portion such that the article supporting portion is located midway between the first guide portion and the second guide portion in the first direction.
