OBJECT: To realize a wiping sheet with sufficient flexibility, high adhesion strength, easy attachment on concavo-convex surface, good adhesiveness and durability. A gateway terminal receives the user link beam for receiving a first received signal and a second received signal thereafter. The representations are exact, so the resulting solutions are not approximations. The flipper arm preferably is mounted to pivot around an axis, and the spring preferably biases the flipper arm around the axis toward the conveyor. When a vehicle transverse direction distance between the tire driving devices 118 is to be changed in accordance with a tread base of the vehicle, the first sliding base 34R is moved.
