Means for fixing the dustproof screen to the front surface of the radiator is described in Japanese Utility Model Application Publication No. 138826/1983. However, the device described in this publication does not fix the frame of the dustproof screen with clamp fittings, but rather the dustproof screen itself is attached so as to be sandwiched between the radiator and the fan shroud, and is placed near the center of the dustproof screen. A fixing structure is described in which an elastic rod-like body presses the radiator toward the radiator.

(Problem to be solved by the invention) In order to attach a clamping tab to a frame such as a screen frame, the tab is a small piece of metal, which requires time and effort to manufacture, and it is troublesome to attach it to the frame. . In other words, although the tab is a small piece, it is thick and therefore requires more man-hours to process. Further, spot welding is also performed when attaching to the frame, but the position is not stable, which requires more man-hours and has the disadvantage that the attachment position may shift.

(Means for Solving the Problems) The present invention provides a method for forming a frame by bending a sheet metal or stacking two sheet metals and sandwiching a thin film such as a screen between the sheet metals. The body is fixed to each other by a concave crimped part made by integrally crimping two sheet metals on the front and back and a thin film body interposed in between, and the concave part of the crimped part is used to lock the frame with the clamp. This is a screen locking structure characterized by having two parts.

(Function) The two sheet metals forming the frame and the thin film interposed between the sheet metals are crimped in a concave shape to form an integral body, and the entire circumference of the frame is formed by a plurality of crimped parts. , the frame is fixed with a clamp fitting using the caulking part. Therefore, the clamp groove is formed without attaching the tab to the frame as in the conventional case, and the caulking part for fixing the thin film body is directly applied to the clamp locking part.

As shown in Fig. 3, when attaching the screen 2 to the engine body 1, there are four clamp locations.
The frame 5 of the screen 2 is secured to the engine body 1 by a clamp fitting 7. The caulking portions 8 are appropriately arranged in the longitudinal direction at the center of the width of the sheet metal constituting the frame body 5 to fix the wire mesh 4 to the frame body 5, so there are a large number of caulking portions 8. A part of the caulking part 8 is also used as a clamp locking part. In the present invention, there is no need to attach a tab on the frame 5 as in the conventional case.

(Effects of the invention) The present invention forms a frame by bending a sheet metal or stacking two sheet metals as described above, and sandwiching a thin film such as a screen between the sheet metals. The front and back two sheet metals and the thin film body interposed in the middle are integrally fixed to each other by a concave caulking part, and the concave part of the caulking part is used as a clamp locking part, and the frame body is attached to the engine body. Since it is fixed at a predetermined location, the thickness of the frame was increased by the thickness of the tab in the past due to the presence of the tab, but with the present invention, the screen as a whole can be made thinner and the tab is unnecessary. Further, according to the present invention, the locking part of the clamp fitting can be a groove or a protrusion having a smoother rounded shape than a tab, which has the effect of making it possible to attach and detach the clamp smoothly. Also, since tabs are not required, there is an effect of reducing tab machining and installation man-hours.
