PURPOSE: To comprise an accessory on the main body of a bed, etc., freely loadably/unloadably without using a tool. CONSTITUTION: A mounting member 17 inserted to a mounting hole 16 for insert type side fence on a side frame 10 is implanted on the base horizontal frame 12 of a foldable side fence 11. An inclined face 18 is formed on the tip of the mounting member 17, and an operating shaft 19 is pierced through from the upper part of the base horizontal frame 12 via the mounting member 17 so as to move upward/-downward in an axial direction, and a movable piece 21 is provided at the tip. An inclined face 21 is provided on the movable piece 20 so as to confront with the inclined face 18, and an insertion hole 22 of diameter larger than that of the operating shaft 19 is formed in a center part. The movable piece 20 is moved with play to the side by inserting the operating shaft 10 into the insertion hole 22, and also, it is supported by suspending by a flange part 23 at the tip of the operating shaft 19. While, the upper terminal part of the operating shaft 19 is protruded over the base horizontal frame 12, and a control lever 25 to move the operating shaft 19 upward/downward in the axial direction is supported with bearings on the upper terminal part. |
