<P>PROBLEM TO BE SOLVED: To reduce damage caused by contact with various films set in/out of an agricultural greenhouse. <P>SOLUTION: The agricultural film support member can reduce damage caused by contact with a film because the friction resistance in a contact part in contact with the film is low. It is important for various equipment used in the agricultural greenhouse to prevent impairment of sunlight conditions caused by setting the equipment, and also for the agricultural film support member, it is desirable that the area of projection of the agricultural film support member when the agricultural film support member is set is as small as possible. Accordingly, the outer diameter (diameter) of the agricultural film support member is desired to be as narrow as possible. However, the narrower the diameter of the agricultural film support member is, the greater the damage to the film caused by local breaking is. As the friction resistance in the contact part is small, the degree of damage to the film caused by the local breaking can be reduced even if the outer diameter is narrow. By using a narrower agricultural film support member, the sunlight conditions can be further improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
