[Action]

 In the side fence of the bed according to the present invention as described above, the locking cylinder provided at the lower end of the column is inserted into the mounting hole provided in the side frame of the bed, and the operating shaft provided in the column is moved to one side. When it is rotated and pulled up, the wedge (or sphere) fixed to the tip pushes the locking cylinder outward from the tip with the slit part provided in the axial direction, and the tip of the locking cylinder becomes the mounting hole. It is pressed against the inner wall to prevent it from coming off. Further, when the actuating rod is rotated to the other side and lowered downward, the locking cylinder pushed and expanded by the wedge body is narrowed down so that it can be easily pulled out from the mounting hole. In this case, since one end of the locking cylinder is fixed to the lower end of the column, and the slit is provided from the tip side, the slit part expands when it is pulled out, making it difficult to pull out, or the locking barrel falls off from the column. There is no fear of doing anything.
