- Helical gears 22a and 22b are cylindrical gears formed in a winding with helical teeth, and transmit rotational motion between two parallel support columns 11a and 12b.
- Helical gears are spur gears. There is no backslash (play between the teeth where the pair of gears mesh), and the meshing is smoother than that of the spur gear. No noise is generated. This noise problem becomes particularly prominent when spur gears are formed of metal materials in order to support the weight when the panel body is large or made of metal and has a weight force S. However, if a helical gear is used, such noise is not generated and the folding door can be opened and closed quietly.

- the helical gears 22a and 22b generate a thrust load (a load or a pressure parallel to the axial direction of the rotating shaft) in the axial direction (longitudinal direction) because the teeth are twisted.
- the plate 23 must be strong enough to support the axial thrust.
- the details of the pillars 11a, 12a and the helical gears 22a, 22b will be described with reference to FIG. 7 and FIG.
- the support columns 11a and 12a are formed in a hollow cylinder shape that is substantially larger than a semicircle, and groove portions llal and 12al are provided at the center of the semicircle over the entire length from the upper end to the lower end.

- the sealing members 28a and 28b having the same elasticity as the above are attached.
- the helical gears 22a and 22b are formed by two-stage cylindrical force having different diameters. That is, as shown in FIG. 8, helical gear teeth are cut on the outer periphery of a large diameter, and the portion corresponding to the string contacting the panel bodies 11a, 12a is cut to form a substantially semicircular shape. The small diameter portion is cut into a shape inscribed in the support pillars 11a and 12a to form fitting portions 22al and 22bl to be inserted into the support pillars 11a and 12a.
- the helical gears 22a and 22b are attached to the support bodies 11a and 12a in the following procedure. First, the helical gear 26a and 22b are meshed with each other, and the helical gear 26a and 22b are meshed with each other. Connect so that it can rotate freely. Then, the fitting portions 22al and 22bl of the helical gears 22a and 22b are inserted into the support pillars 11a and 12a, and the screw 28 is attached to the support pillars 11a and 12a. The helical gears 22a and 22b are fixed to the column bodies 11a and 12a by pressing the tip of the screw 28 against the bottom of the recess 30 provided by the progressive insertion.
