PROBLEM TO BE SOLVED: To provide a bed capable of commonly corresponding to multiple sizes of floor plates different in length in a single bed main body, facilitating cost-down, and achieving weight saving.SOLUTION: A bed includes a base frame to be placed on a floor surface; a lifting frame to be arranged above the base frame; a lifting support mechanism for supporting the lifting frame to be liftable with respect to the base frame; and a lifting drive device for lifting the lifting frame. The lifting frame is configured by combining long materials so as to form a long rectangular shape as a whole. Each one of the pair of long-side parts in a length direction in the lifting frame is divided into two or more portions in the length direction with the use of two or more long-side side division frame pieces. The two or more long-side side division frame pieces are mutually coupled to be slidable in the length direction of the long-side parts. The length of the long-side parts is adjustable in the length direction of the lifting frame.SELECTED DRAWING: Figure 1 |
