Abstract
A device used to lay line elements such as electric and/or fluid lines between a stationary housing and a moving housing. The device includes a double pipe structure having an inner pipe member and an outer pipe member. The outer pipe member is attached to the moving housing and rotatably supported by the stationary housing. The inner and outer pipe members are arranged in a generally coaxial relationship and coupled to each other by a coupling member. The line elements, which extend between a holding portion on the stationary housing and a holding portion on the moving housing, are divided into first and second groups, and the first group of line elements is laid to extend through an inner hole of the inner pipe member while the second group of line elements is laid to extend through an annular gap formed between the inner and outer pipe members.
