To stabilize the balance of a center of gravity of a bed device.SOLUTION: A bed device 10 includes a bed 11, a medical instrument attaching rod 38 having an engagement part 81 in the upper part, and a rod support part 36 for supporting a lower end 82 of the medical instrument attaching rod. The bed device 10 also includes a support frame 12 for supporting the bed. The bed is longer in a longitudinal direction than in a lateral direction in the planar view. A bent part 85 is formed to the medical instrument attaching rod so that the engagement part is arranged eccentrically with respect to an axial center of the lower end, and the medical instrument attaching rod is supported by the rod support part in a state that the engagement part is eccentric in the longitudinal direction with respect to the axial center of the lower end.SELECTED DRAWING: Figure 1
