On the other hand, the conventional takeout device is designed to increase the friction coefficient of the ground by installing the withdrawal wheels in front and rear to secure the straight running reliability of the movable unit grandstand. Not only did the linear straightness of the operation deteriorate, it also caused the problem of losing the linearity of the operation unit when the stand was operated, thus preventing the unfolding and folding of the driven unit seats.

The above problem is caused because the withdrawal wheel of the withdrawal device is placed on the uneven ground so that the withdrawal wheel of any one of the withdrawal wheels is not in contact with the ground, so that the idle wheel does not move forward or backward, while the withdrawal of the remaining wheel is withdrawn. The wheels move forward or backward so that the withdrawal device loses the moving straightness. When the withdrawal device loses the moving straightness, the moving direction of the moving unit grandstand also changes, so the interlocking linearity of the driven unit grandstands is also lost. In order to solve this problem, in order to solve this problem, the linearity of the movable unit grandstand is lost and at the same time the operation of the movable unit grandstand is stopped. This is because The same effect was able to prevent the continuous, yet smoothly.

The present invention was invented with the object of solving the problems caused by the combined relationship between the conventional drawing device and the movable unit grandstand as described above at the same time in the present invention. This can be maintained, and it is intended to solve the above problems by installing a withdrawal device in the movable unit grandstand that can stably support both sides of the movable unit grandstand.
