PURPOSE:To prevent shoe characteristics from being degraded with time by securing a signal branching conductor on a signal branching base which is movable to the longer direction of a housing, in parallel with a signal transmission conductor while it is insulated. CONSTITUTION:A base B is secured movably on a duct housing 12 to the longer direction wherein a signal branching conductor 14 is provided while being insulated. This signal branching conductor 14 is arranged in parallel with a signal transmission conductor 11. As a result, both of the signal transmission conductor 11 and the signal branching conductor 14 act as a strip line type directional coupler whereby a signal transmission path can be branched under a non-contact condition between the signal transmission conductor 11 and signal branching conductor 14. Accordingly, when a signal branching base 13 is moved to the longer direction of a signal transmission duct 1, shoe characteristics are not degraded with time whereby transmission troubles can be prevented.
