PROBLEM TO BE SOLVED: To provide a caster fixing structure for a bed, etc. which can be miniaturized while securing strength and is especially suitable to lower the bed. SOLUTION: A supporting arm 16 to be fixed to a base part frame 11 is integrally constituted with a cap-shaped caster receiver 12 supporting a yoke 14 holding a wheel 13 through a pivot receiver. This supporting arm 16 is made of an aluminum die-casting like the caster receiver 12 and is curved upward. The position of a fixing spot with the frame 11 is almost at the same height as the upper part of the wheel 13, which is lower than the caster receiver 12. |
