The pantograph in each row is formed in X-shape with two diagonal members 15 intersecting in X-shape, and a bracket 16 for horizontally connecting the respective intersection parts of the X-shape is provided between the two rows of pantographs. Each of the diagonal members 15 of the pantograph is perpendicularly turnable around each intersection part used as a shaft, and the bracket is vertically movable and fixable at a predetermined height.
