ELECTRIC WIRING STRUCTURE OF HOLLOW ROTATOR

摘要

A relay connector (23) is secured to a hollow hole forming member (22) provided with a hollow hole (21) in a hollow rotator (20) so as to be coaxially located in the hollow hole (21) in order to draw out an electric wire group from the side of one end surface in the direction of a rotation central axis line (20a) of the hollow rotator (20) to the side of the other end surface by using the hollow hole (21) passing through in the direction of the rotation central axis line (20a) in the hollow rotator (20). A first connection section (24) is formed on one end of the direction of the rotation central axis line (20a) of the relay connector (23) and a second connection section (25) is formed on the other end thereof. A first electric wire side connector (28) attached to the end of a first electric wire group (26) is electrically and detachably connected to the first connection section (24) and a second electric wire side connector (29) attached to the end of a second electric wire group (27) is electrically and detachably connected to the second connection section (25).
