PROBLEM TO BE SOLVED: To provide a rain-cover structure in horizontally spread net facilities made by surrounding a cultivation field with an insect proof net, preventing the field from getting wet with rainfall, and easy and inexpensive to add to existing horizontally spread net facilities by minimum necessary reconstruction. SOLUTION: This rain-cover structure comprises installing and supporting a tub placing means using beam members which are arranged at prescribed intervals on the ceiling part of the horizontally spread net facilities made by surrounding a cultivation field with an insect proof net, and connecting and fixing arch pipes between beam members adjacent to each other using the tub placing means. As a result of this, it is possible to place and support a tub on the upper side of the beam member, and lead rainwater falling on a rain-cover sheet to a gutter and discharge. As the arch pipes between beam members adjacent to each other are connected and fixed using the tub placing means, it is possible to stretch the rain-cover sheet on each of the arch pipes and prevent the horizontally spread net facilities from getting wet with rainfall.
