PROBLEM TO BE SOLVED: To mount attachments such as side fences by enabling the attachments to be freely movably held on the frame of a bed or the like through a much easier fixing operation without play. SOLUTION: A pair of fixtures 3, 3 are held on both ends of an auxiliary mounting frame 4 while being energized by a torsion spring 5 in such a way as to be oscillatable about an axis perpendicular to the longitudinal direction of the auxiliary mounting frame 4. The fixture 3 has an integrally formed lower receiver 6 and an upper receiver 7 of an L-shaped cross section, the lower receiver 6 and the upper receiver 7 being set to be offset from each other in the longitudinal direction of a side frame 2 to be mounted. This offset enables mounting of attachments on the side frame 2 through oscillation about the auxiliary mounting frame 4 even if the lower receiver 6 and the upper receiver 7 are integrally formed. |
