However, the rubber material 2 on the inside of the curve is in a state of protruding to the inside due to the volume change due to the reduction.
Since there may be a hindrance after the completion of the construction, it is possible to use a method of absorbing the volume change due to the reduction by providing a groove having a predetermined width in the rubber material 2 on the side surface inside the curve.
