2. Description of the Related Art With the widespread use of institutional horticulture, various fruits and vegetables can be cultivated even in low temperature seasons such as winter, and year-round production and supply can help farmers stabilize and improve their income. It brings and enriches consumers' lives. This has a great effect due to the spread of greenhouse cultivation in the vinyl greenhouse method, which requires less investment than the conventional glass greenhouse method. In the current house cultivation, it is general to spread a film sheet on the framework of a pipe house to create an environment suitable for crop cultivation, and to carry out cultivation there.
A pipe house is made by spreading a film sheet of polyvinyl chloride resin or polyolefin resin as a film sheet for house cultivation on a frame of a pipe house installed using a plurality of arch pipes. In general, these stretched films and sheets are contaminated with the passage of time, resulting in poor sunlight transmission, damage, and deterioration in functions such as anti-fog properties. It is necessary to remove it and re-expand it in the next demand period, or replace it with a new one every one to two years. This spreading work
This is done by manually pulling the film sheet from one end to the other end in the longitudinal direction of the skeleton, which requires a lot of manpower, and some proposals such as the use of tools for labor saving have been made. For example, use of a guide roller (JP-A-2-215317) (JP-A-6-141690) or use of a sled.

However, even if such a tool is used, there are two workers who pull the film sheet from both sides by holding both ears at one end of the film sheet and pulling out the film sheet from the ground. One worker is required to send to the upper part of one end, and at least three workers are required in total. In the case of a large-sized house, if the house is long or there is wind, the film sheet is spread on the side surface, so that more workers are actually required. On the other hand, with the lack of manpower and aging of farmers, automation and labor saving are being promoted, and improvement is strongly required.
