  • Patent number: 11338688
    Abstract: A vehicle charging system includes a second fitting body. The second fitting body includes a projection-side electrode holding unit which includes a projection, the projection holding a second electrode member and projecting in a facing direction, and an elastic body which supports the projection-side electrode holding unit in the facing direction and is elastically deformable in a compression direction which is one direction of the facing direction. The elastic body moves the projection-side electrode holding unit in the compression direction from an initial position by being compressed by a load in the compression direction applied to the projection-side electrode holding unit and moves the projection-side electrode holding unit to the initial position by being restored when the load is removed.
