Next, the operation when using the bed apparatus having the above configuration will be described.
[0029]
When the side fence 21 is removed from the bed main body 1, the support member 20 is held on the lower surface side of the bed main body 1 in a posture lying down substantially horizontally. At this time, the first bolt 11 is located at the other end of the first groove portion 7 of the guide groove 6, so that the support member 20 is substantially on the inner surface side of the mounting member 4 as shown by a chain line in FIG. 2. It becomes the 1st state which laid down horizontally. In this first state, the sliding shaft 9 is restricted from rotating in the circumferential direction with respect to the guide member 5 because the first bolt 11 is engaged with the first groove portion 7. That is, the support member 20 is reliably held in a state where it lies horizontally.
[0030]
When the side fence 21 is attached to the bed main body 1, an angle range in which the second bolt 16 is advanced and retracted in advance and the first bolt 11 can rotate in the circumferential direction of the guide member 5 in the guide groove 6. Is set to be approximately 90 degrees.

Further, when the support member 20 is in the upright posture, the first bolt 11 abuts on the tip 17 of the second bolt 16, so that the pair of support members 20 are positioned in parallel with the axes substantially vertical. Is done. Therefore, the pair of support shafts 23 of the side fence 21 can be quickly and easily inserted into the support member 20.
[0035]
When the side fence 21 is removed from the bed main body 1, the support members 20 and the sliding shaft 9 are stored and held on the lower surface side of the bed main body 1 as described above.
[0036]
That is, the support members 20 are rotated in the direction indicated by the arrow Y in FIGS. 2 and 4, and then the slide shaft 9 is slid until the first bolt 11 reaches one end of the first groove portion 7. For example, as described above, the support member 20 can be supported on the lower surface of the bed main body 1 by lying down substantially horizontally. Therefore, when the side fence 21 is not used, the support member 20 does not protrude from the side of the bed main body 1 and get in the way.
