The present invention relates to a free power-automatic flushing device using human body weight, which includes: a sensing cap having a screw hole formed inside, a sensing part which is located at a lavatory and has an embedded elastic spring inserted into the screw hole formed the sensing cap, screw protruding parts rotatably coupled with the screw hole formed on the sensing cap of the sensing part, a rotational part having a gear formed at the lower of the screw protruding part, a rack, a fixing part, a movement part, a first wire which includes one side wound by the first fixing part formed at the fixing part while being fixed to the first protruding part of the protruding part formed on the rack and the other end fixed to a movement member formed on the movement part, and a second wire which includes one side wound by the second fixing part formed at the fixing part and the movement member formed on the movement part while being fixed to the second protruding part of the protruding part formed on the rack and the other end fixed to a drainage cover of the lavatory. The present invention allows a user to cleanly use the lavatory by automatically drain water stored in the lavatory in such a manner that the drainage cover of the lavatory is automatically opened and closed as the sensing part and the rotational part operate when the user seats on or stands up from a seat of the lavatory, allows the sensing part, the rotational part, the rack, the fixing part, the movement part, the first wire, and the second wire to be used in a state free of power without any power device, and has advantages in that it can be conveniently manufactured thanks to a simple structure and manufacturing costs can be reduced to achieve economic feasibility, and it can be maintained conveniently. |
