２及びシリンダヘツド５を冷却する。 A conventional general-purpose air-cooled engine will be explained with reference to FIGS. 1 to 3. 1 is the crankcase,
2 is a cylinder, 3 is a carburetor, 4 is a fan, 5 is a cylinder head, 6 is an air guide plate, 7 is a side plate, 8 is a camshaft, 9 is a crankshaft, 10 is a guide plate, and the side wall 11 of the air guide plate 6 The front plate 12 is spot welded at two locations A and B, and the front plate 12 is spot welded at three bent portions 13. Reference numeral 14 denotes a concave portion formed in the front plate 12 of the air guide plate 6, and a name plate (not shown) or the like is attached thereto. Cooling air 15 generated by fan 4
is guided by the guide plate 10 to cool the cylinder 2 and cylinder head 5 as shown by arrow 6.

性が悪い。 When spot welding the guide plate 10 to the air guide plate 6 with the air guide plate configured as described above, both ends A and B of the guide plate 10 and the bent portion 13 are aligned in the spot welding direction.
Because they differ by 90 degrees, it is difficult to spot weld them at the same time. In addition, since the direction of spot welding is different, it is necessary to change the direction of the baffle plate 10 each time, resulting in poor productivity.
本考案の目的は同時スポツト溶接が可能な導風
板を提供するにある。 The object of the present invention is to provide a baffle plate that can be simultaneously spot welded.
