PURPOSE: An automatically moving bollard is provided to be automatically installed and removed to/from a housing since torque of a motor is converted into linear driving force through a gear unit between an exposed body and a buried housing. CONSTITUTION: An automatically moving bollard comprises a housing(3), a body(5), a rack bar, a gear unit, a motor unit(7), a seal unit(11) and a sensing unit(S). The housing is formed in a cylinder shape, a flange is fixed to the upper end of the housing and a lower plate is welded to the lower end of the housing and is buried at the ground. The body is formed in a smaller cylinder than the housing in diameter, is installed or removed to/from the housing. A reflective sheet is attached along the outer circumferential surface of the upper end of the body. An upper plate is fixed to the upper end of the body. The rack bar is vertically arranged through the inside of the body.
