PURPOSE:To automatically rotate a back receiving part, a hip receiving part, and a leg receiving part to a fixed bed frame by 90 deg., respectively, and automatically bring up the leg receiving part at the time of rotation by providing a rotating mechanism for rotating respective rotary bed frames by screw cylinder movement and an interlocking mechanism for bending the back receiving part and the leg receiving part. CONSTITUTION:When a screw shaft 12 is rotated to move a screw cylinder 13 on a motor 10 side, a cam roller 33a is pushed by the back surface of a moving cam body 20 to stand up a back receiving part 23b through an operation arm 33. Then, a cam roller 34a runs on the inclined surface of a moving cam body 21 to tilt a hip receiving part 23c, and a cam roller 35a similarly raises a leg receiving part 23d. In the stage of raising the leg receiving part 23d, when the screw cylinder 13 is moved on the motor 10 side in the state, where a pin 18 is inserted into either one of right and left holes 19, the pin 18 is fitted to a cam channel (a) or (b) to twist the screw shaft 13 side in one side of left and right, and rotary be frames are rotated by 90 deg., respectively. |
