And the supporting means are springs disposed at four corners between the second holding member and the fixing member.

[0010]

According to the present invention, when the sliding door is closed, the concave and convex inclined guide surfaces interfere with each other if the first and second holding members are in the correct alignment. Without contact, the first and second terminals come into contact with each other, and power can be supplied.

If the first and second holding members are misaligned as a result of the door mounting adjustment or the like, the concave shape and the sliding door are moved in the closing direction. At least one of the holding members supported by the supporting means so as to be movable in the vertical and horizontal directions of the vehicle is moved in the direction in which the misalignment is eliminated, by the two inclined guide surfaces having a convex shape coming into contact with each other and further moving the slide door. Is done.
Thus, the terminal held by the holding member moves in the same manner, and the two terminals come into contact in a state of being finally aligned.
