Summary:PROBLEM TO BE SOLVED: To provide a stretch device for an exterior covering film for a greenhouse enabling securely and easily stretching the exterior covering film to be set in an openable and closable manner so as to be imparted with a desired tension without damage, and to provide a stretch method for the exterior covering film for the greenhouse using the stretch device. SOLUTION: The stretch method comprises connecting the base edge of a first belt member 11 to a rolling pipe 40 fixed with the edge of the exterior covering film 30 and setting a loop part 11c as a part to-be-engaged on a free edge. The hook member 12d of a second belt member 12 constituting a tension-imparting member is engaged with the loop part 11c so as to adjust the length of the second belt member 12. As a result, the exterior covering film 30 can be securely and easily stretched without damage. COPYRIGHT: (C)2004,JPO
