Are parallel to each other in the horizontal state, and the thigh belt and the waist belt are connected by a connecting belt at the front and back (butt) of the worker. Since this connecting belt uses a belt that stretches, when the waist is bent, the feeling of tension is lost by stretching it along the line of the body. However, since the extending belt continues to stretch until it breaks, there is also a drawback that the waist belt is displaced toward the chest when the fall is prevented.

Further, since the thigh belt is structured to be connected inside the thigh, when moving, etc., the connecting devices of both feet contact each other on the inside of the thigh, which may cause uncomfortable feelings.
Furthermore, since the left and right thigh belts have the same shape and the same color, they may be worn on opposite thighs.
