The present invention relates to a running device of a sliding door for a cold storage warehouse and, more particularly, to a running device of a sliding door for a cold storage warehouse which includes a door bottom movement preventing and attaching unit between the lower side of the door and one or both sides of the bottom of an entrance to prevent the movement of the door bottom when a door is opened or closed and to automatically attaching the inner side of the lower side of the door to the warehouse when the door is closed at the same time. Therefore, the running device of a sliding door for a cold storage warehouse remarkably increases airtightness between the inner side of the door and the outside of the entrance of the cold storage warehouse and prevents the door from being twisted or separated by completely preventing a center roller and a side roller from being separated from a slope rail due to an impact from the opening and closing of the door. |
