<P>PROBLEM TO BE SOLVED: To provide a sheet-stretching tool for feeding a sheet and exchanging the direction of a sheet with which setting work even at a high place can be safely and simply performed and the sheet can be set up without depending on a distance between portal-type skeleton bodies. <P>SOLUTION: The sheet-stretching tool for feeding a sheet is set to the portal-type skeleton bodies composing the skeleton of a plastic greenhouse and can hold a stretched plastic sheet. The sheet-stretching tool for feeding a sheet includes: a rod member turnable in a virtual space parallel to a virtual vertical surface in which the portal-type skeleton bodies reside; and a connection member with which the rod member is held to any one of the portal-type skeleton bodies. The connection member is provided with a portal-type skeleton-gripping part which grips any one of the portal-type skeleton bodies, and a part to which the rod member is pivotally attached where one longitudinal end part of the rod member is pivotally attached. <P>COPYRIGHT: (C)2012,JPO&INPIT |
