PROBLEM TO BE SOLVED: To provide a screen stretching frame that prevents deformation of a stretched screen even when the screen stretching frame is removed from a screen stretching jig during storage and transportation.SOLUTION: Four frame members, which constitute a screen stretching frame in which four frame members are coupled in a rectangular shape by means such as welding, are separated and coupled by corner members. These connection parts are inclined with respect to a longitudinal direction of the frame members and gaps are provided in the connection parts. Elastic bodies may be interposed in the connection parts of the four frame members constituting the screen stretching frame. Or, the connection parts are formed perpendicularly to the longitudinal direction and the elastic bodies are interposed in the connection parts.SELECTED DRAWING: Figure 28 |
