A tray for a spiral conveyor is configured from an outer tray, an inner tray which is placed over the inside of the outer tray, and a vibration damping material which is interposed between the outer tray and the inner tray. The tray has a fixing means for detachably fixing the inner tray and the vibration damping material to the outer tray on the outside of a conveyance spiral casing. The vibration damping material may be a single vibration damping material which is continuous over substantially all of the area between the outer tray and the inner tray, or may alternatively be arranged so as to be separated into a lower vibration damping material that is provided in a noise generation area with which a conveyance spiral is brought into contact and upper vibration damping materials that are provided in a noise propagation area including the fixed portion.
