The present invention relates to a drum for winding a wire of a vinyl greenhouse. In particular, an opening and closing wire inside the vinyl greenhouse are wound around the drum, then an end portion of the wire is connected to an insulating cover. Therefore, when the insulation cover is opened or closed by winding and unwinding operations of the opening and closing wire according to the operation direction of a reciprocal motor, the wire is prevented from being entangled. An assembling process can be easily performed by setting an elasticity of a spring inserted between a holder and a flange of the drum in advance. Moreover, the drum is transferred and stored in an easy manner because the holder, the flange, and a winding rotor can be assembled and disassembled. |
