摘要： PURPOSE:To prevent dislodging of end caps and to reduce the cost of a flag hinge by providing plural projections formed by cutting the metal outward in the side edge at the end of vane plates, bending the end parts having the projections into a pipe shape, and spot welding the flat plate-like end caps to the projections of the pipe parts. CONSTITUTION:Mounting holes 14, 15 are opened in one end parts of members 10, 11, and the metal at the top end 16 and bottom end 17 in the end part on the opposite side are cut out to provide plural projections 12, 13 at equal intervals. The end parts are bent into a pipe shape to form pipe parts 4, 5, thereby forming upper and lower vane plates 2, 3. A ring 6 is held between the parts 4 and 5 and a shaft core 7 is passed in said parts. Flat plate-shaped end caps 8, 9 are placed on the open ends having the projections 12, 13 and are fixed to the parts 4, 5 by spot welding. It is also possible to make only one of the vanes 2, 3 and use the same for the other. The dislodging of the end caps in the flag hinge is thus prevented and the cost of the flag hinge is reduced by the inexpensive end caps and the simple projections.
