席。 Spectator seats with a certain angle of inclination are formed by a lower front area in contact with the competition floor and an upper rear area located behind it.The upper rear area is a fixed structure, and the lower front area is made of a The unit floor is created by subdividing the unit floor by dividing lines that roughly follow the radiation from the center and joining lines that are parallel to the boundary line between the rear upper area and the front lower area, while being guided by rails laid on the competition floor surface. A truss member that spans the two carts is installed on the cart, and the upper end of the truss member pivotally supports the unit floor in a scale-like manner.A securing member that can be turned freely is also provided on the cart, and the upper end of the truss member supports the front edge of the unit floor. It is a structure that supports the unit floor, and is supported by these truss members and securing members, and the rear edge of each unit floor is supported by the front edge of the upper rear area or the rear edge of the rear upper area. The front lower tier seats are extended by overlapping the front edge of the unit floor, and the unit floor is rotated vertically using the upper end of the truss member as a fulcrum while being aligned with the securing member and the truss member, and each unit floor is placed directly in front of the rear upper tier seat. A movable viewing seat characterized by a structure that folds in both directions.
