To provide a device for connecting ceiling-traveling rails for allowing a traveling nursing lift to travel under a narrow wall without destroying the narrow wall of an opening part such as a sliding door and without the need for a ceiling reinforcing construction.

This connection device connects the ceiling traveling rails under the narrow wall by using a traveling rail device composed of a mechanism for horizontally moving/elevating and lowering the traveling rails and a turning rail device composed of a mechanism for turning/elevating and lowering the traveling rails. In the connection device, the ceiling traveling rails inside a room and a corridor, or the like, are connected by using a combination of the traveling rail device or the turning rail device and a ceiling traveling rail rack. Further, the individual devices are attached to a self-standing rack and the ceiling traveling rails are freely rearranged.
