The present invention relates to a towing guider for a curtain opening and closing device and, more specifically, to a towing guider for a curtain opening and closing device, wherein a thermokeeping curtain opening and closing device additionally formed to be opened and closed in a longitudinal direction in a greenhouse (vinyl house) does not make a thermokeeping curtain downwardly drooping by dead load. According to the present invention, the towing guider comprises: a pair of towing rollers individually formed in both side front ends of a horizontal direction support unit horizontally spaced apart from the ground by means of multiple vertical direction support units, rotated without a load to support and guide movement of a ring chain circulating along a longitudinal direction of a greenhouse through an operation of a driving unit and to guide opening and closing movement by supporting both ends of a thermokeeping curtain, and opening or closing the thermokeeping curtain while being completely spread; a flow preventing hole penetrating through and coupled with the horizontal direction support unit near to one side of each of the towing rollers so as to fix a position of the towing rollers and limit a bidirectional rotation radius; and a guide bearing for activating opening and closing of the thermokeeping curtain according to the ring chain supported and guided to move, while penetrating through and coupled with the other side of each of the towing rollers. |
