A receptacle, fixed to a first case, has a central conductor portion, an outer conductor portion that concentrically surrounds the central conductor portion, and a receptacle-side convex portion that extends in a connector circumferential direction and is formed on a top end portion of the outer conductor portion. A plug, fixed to a second case, has a plurality of inner contact pieces that make contact with an outer peripheral surface of the central conductor portion with fitting into the receptacle, a plurality of outer contact pieces that extend in a connector axial direction on an outer peripheral surface of the outer conductor portion with intervals therebetween, and plug-side convex portions that are freely displaceable in the connector axial direction in a state of being in surface contact with the outer peripheral surface of the outer conductor portion and are formed on the outer contact pieces of the plug. |
