The slip ring is positioned below the pad side unrotatable member. Further, at least one column side slip ring is disposed concentrically with the boss, and positioned above the column side unrotatable member. A boss plate is disposed around the boss and at least one holder is fixed to the boss plate. Pad and column side contact pins are supported by the holder, and biased toward opposite direction to each other by a spring positioned inside the holder.
