BEST MODE FOR CARRYING OUT THE INVENTION A buttocks support 11 is laid on a buttocks 17 of a disabled person 18 sitting on a bed or a wheelchair, and both side straps 11 ', 11' of the buttocks support 11 are extended or retractable at both ends of the horizontal rod 7 in this state. The arm 8 is detachably connected to the lower end of the arm 8 by a mounting ring 22 (FIG. 2).

In this state, when the disabled person 18 inserts both knees 16, 16 into the vertical grooved mats 5, 5, and presses a switch, the electric motor 10 'of the rear traction device 10 rotates and the torque limiter 10a The take-up drum 10b rotates via the guide roller 23, and the traction strip 10 "is wound on the take-up drum 10b via the guide roller 23. 23, the buttocks support 11 is pulled up, the horizontal rod 7 shifts slightly behind the upright rods 2, 2, and the up-and-down rotatable arm 6 slightly tilts slightly rearward of the upright rods 2, 2, so that the upper part is lifted. The tip of the light blocking arm 26 is the upper photoelectric tube sensor 2
4, the motor 10 'is stopped by the signal and the towing is stopped. However, before the base of the vertically movable rotatable arm 6 comes into contact with the stopper 29, the torque limiter 10a is opened. Immediately thereafter, the electric motor 10 'is stopped, and the disabled person 18 stands upright with the knees and buttocks 17 supported by the vertical grooved mats 5, 5 and the buttocks support 11 (FIG. 5). In addition, buttocks support 11, both side hanging strap 11 ', 1
When 1 'or the like is caught on the wheelchair and applied to the rear traction device 10 with a certain force or more, the torque limiter 10a opens and the rear traction is not performed, so that the switch is turned off and the motor 10' is stopped.

In addition, the disabled person 18 can be seated on the bed or wheelchair by rotating the vertically movable arm 6 forward by the operation opposite to that described above and lowering the buttocks support 11 to the bed or wheelchair. At this time, the lower photoelectric tube sensor 25 is cut off by the tip of the lower light blocking arm 27 provided below the rotatable arm 6, and the motor 1
Stop 0 'and open the torque limiter 10a.

Then, the buttocks support 11 is removed from between the bed or the wheelchair and the buttocks 17, and the disabled person 18 can lie on the bed or sit on a wheelchair.
