The front plate is placed parallel with the rear plate with a certain gap and has a freight delivery and load vessel and so on is installed thereon. The load cell is placed between the rear plate and the front plate and has the upper end fixed to the rear plate and the lower end fixed to the front plate. The elastic boards integrally connect the upper ends of the lower ends of the rear plate and the front plate respectively.
