An intermediate transfer device is located upwardly of an article delivering and receiving portion and downwardly of a ceiling transport vehicle. A transfer device grip is provided such that the intermediate transfer device is in vertical alignment with the ceiling transport vehicle and the article delivering and receiving portion and is capable of traveling, while guided and supported by a guiding support, to and among a transfer position for the delivering and receiving portion, a transfer position for the intermediate rack, a transfer-time retracted position, and a temporary-storage-time retracted. The guiding support is configured to form a space through which the grip portion and an article can pass in the vertical direction when the ceiling transport vehicle transfers the article.
