[Detailed Description of the Invention] [Purpose of the Invention] "Field of Industrial Application" The present invention relates to a sheet metal operating device used as an operating section of an opening/closing device for an opening such as a louver window or a casement window.

"Prior Art" FIG. 12 is a cross-sectional view of a louver window in the inside and outside direction. When the handle 2 of the operating device 1 attached to the opening is rotated, the arm 4 rotates around a horizontal axis 3 perpendicular to the plane of the paper, and the arm 4 is pivoted to the other end of the link 5 via a link 5 pivoted to the end of the arm 4. Move the interlocking rod 6 that has arrived. The interlocking rods 6 along the vertical frame 7 are pivotally connected to the arms 8a of the blades 8, which are respectively pivotally connected to the vertical frame 7, so that when the arms 8a are rotated, the blades 8 rotate, and the blades 8 mutually rotate. Close it with a heavy weight,
The blades 8 are opened and released.

FIG. 13 shows an example of a casement window, in which the operating device 1 is attached to the lower frame 13 at the other end of the link 12, one end of which is pivotally connected to the lower stile of the opening shoji 11, which is pivotally attached to the vertical frame 7 on one stile side. The four ends of the arm are pivotally connected. By rotating the arm 4 around the vertical axis 3,
The link 12 opens and pushes and pulls the lower stile of the shoji 9 to open and close the shoji 11.

FIG. 14 is a plan view of a conventional example of an operating device used in the operating section of a window opening/closing device as described above, FIG. 15 is a front view of FIG. 14, and FIG. 16 is a B--FIG.
It is a sectional view of B.

b, and a mounting hole 20a is provided in the mounting flange 14b. The container-shaped main body portion 14a has a planar shape of 14th.
As shown in the figure, a substantially cylindrical boss 14d projects obliquely from one trapezoidal side wall 14c (FIG. 15), and the inside thereof forms a worm housing hole 16 into which a worm 15 is inserted. The hole 16 communicates with the container-shaped main body 14a, and the worm 15 is rotatably supported by a support shaft 3 press-fitted into a shaft support hole 17 provided in the side walls 14c, 14'c of the container-shaped main body 14a. The worm wheel 18 is engaged with the worm wheel 18. The arm 4 described above is integrally formed on the worm wheel 18.
