According to the present invention, an automatic buckle comprises: a body unit having an upper coupling unit and a lower coupling unit disposed respectively on rear portions of an upper portion and a lower portion thereof; a support shaft coupled between the upper coupling unit and the lower coupling unit; and a fixation unit spaced to allow an insertion unit to be formed and coupled to the support shaft, wherein the insertion unit is arranged between the fixation unit and a rear lateral surface of the body unit and is moved when a belt is inserted. The fixation unit comprises: a rotation member having a rotation hole coupled to the support shaft to be able to rotate and penetrating the rotation member and a pressing unit protruding from an upper portion thereof; a contacting member disposed integrally on an outer circumference surface of the rotation member to cover the surface and having contacting protrusion formed on an outer circumference surface of the body unit facing a rear lateral surface of the body unit to allow the belt to be in contact with the same; and an elastic member coupled to the support shaft, whose one end is fixed to the lower coupling unit and the other end fixed to the rotation member and applying elastic force to allow the contacting protrusion to rotate toward the rear lateral surface of the body unit. The rear lateral surfaces of the rotation unit, the contacting member, the upper coupling unit and the lower coupling unit are flat. The rear lateral surfaces of the rotation member and the contacting member are disposed on the same plane as the rear lateral surfaces of the upper coupling unit and the lower coupling unit or inserted inwardly instead of being protruding outwardly. |
