A rear spoiler arrangement for a vehicle has at least one rear spoiler, that can be moved in the vertical direction of the vehicle between a rest position and a functional position. Its design characteristics maximize aerodynamic performance, speed, efficiency, comfort and range in the operational affect of carrying passengers over long distances at very high flight speeds and Mach numbers, generally above Mach 4. Further, the bag only has one film be embossed, and thus the manufacturing process thereof is simplified and at low cost, and the bag is easy to wash. The second conductor includes a second conductive loop disposed substantially within the encapsulation proximate to the first conductive loop to provide a communication link between the first and second conductors. The locking arm 13, since an elastic deformation portion 17 is extended from a proximal end portion 16 to the fixing projection 14 linearly in a slant state, and an arm portion 18 is extended from the fixing projection 14 along an outer surface 12A, is V-shaped; and between an end portion 18A of the arm portion 18 and the connector housing 11, space 19 is formed.
