ABSTRACT:
A contact device that has decreased contact pressure against a conductor caused by elastic repulsion force of a spring contact, to thereby enable suppressing friction and reducing electrical-resistance. The contact device includes first and second conductors arranged on a same axis and moved in their axis direction to fit to each other, a spring contact fitted to an installation groove of the second conductor, and a conductive contact piece arranged between a fitting face of the first conductors and the spring contact, so that electric current flows in a pair of conductors through the conductive spring contact and the conductive contact piece. The spring contact has an elliptical cross section formed of a bare wire being spirally wound with tilting against the winding axis thereof, and the contact piece is divided into a plurality of segments in a direction of the winding axis of the spring contact, and configured to line-contact or face-contact the other of the conductors.
