And in the holder 66, the gear part 62b and the gear part 64b (drive gear) of the 1st gearwheel 62 and the 2nd gearwheel 64 are arrange | positioned.

  As shown in FIGS. 4 and 5, a first opening 66 d and a second opening 66 e are formed in the other side wall 66 c facing the one side wall of the holder 66, respectively. At least a part of the first opening 66d and the second opening 66e are horizontally opposed at the same height position, and as shown in FIG. 6, the first opening 66d and the second opening 66e. The upper end of the portion 66e and the ceiling surface 66f of the holder 66 are set to be flush with each other. At least one of the first opening 66 d and the second opening 66 e has a shape that matches the cross-sectional shape of the horizontal piece 44 a of the support fitting 44. Further, on the front and rear outer surfaces of the holder 66, groove portions 66g that fit into ribs 22e (see FIG. 3) formed in the vertical frame 22c are formed.

  Here, a procedure for assembling the drive mechanism 60 will be described.

  First, in a state where the holder parts 66A and 66B of the holder 66 are disassembled, the first gear 62 and the second gear 64 are assembled to the holder 66 and the holder parts 66A and 66B are fitted, as shown in FIG. The openings 66d and 66e of the holder 66 and the horizontal piece 44a of the support fitting 44 are aligned, and the vertical piece 44b extending in the vertical direction of the support fitting 44 is located outside the other side wall 66c of the holder 66 as shown in FIG. The horizontal piece 44a of the support metal fitting 44 is inserted in the order of the second opening 66e and the first opening 66d of the holder 66 to the position where it abuts the surface of the holder 66, and the holder 66 is penetrated. In the penetrated state, at least one of the first opening 66d and the second opening 66e is fitted with the horizontal piece 44a of the support metal 44, or the horizontal piece 44a of the support metal 44 is the ceiling surface 66f of the holder 66. And the movement of the holder 66 in the vertical and forward / backward directions with respect to the horizontal piece 44a is restricted.

  Further, the upper end of the transmission shaft 36 and one end of the rotary shaft 24 are inserted into the shaft portion 62a of the first gear 62 and the shaft portion 64a of the second gear 64, respectively.

  Next, the holder 66 is inserted into the vertical frame 22c together with the support fitting 44. At this time, the ribs 22e of the vertical frame 22c are inserted into the grooves 66g of the holder 66, respectively, and are arranged in the vertical frame 22c. Thereby, the movement to the left-right direction with respect to the vertical frame 22c of the holder 66 is controlled.

  Next, the upper frame 22a and the vertical frame 22c are combined in a direction orthogonal to each other, the horizontal piece 44a of the support metal fitting 44 is placed inside the inner plate of the upper frame 22a, and the support metal piece 44 inside the inner plate of the vertical frame 22c. The vertical pieces 44b are brought into contact with each other, the positions of the respective screw holes 44c of the support metal fitting 44 are aligned with the positions of the insertion holes 22d of the upper frame 22a and the vertical frame 22c, and the screws 50 are fastened from the outside. As a result, the upper frame 22a and the vertical frame 22c can be assembled by the support bracket 44, and at the same time, the holder 66 can be fixed in the vertical frame 22c in the vertical direction, the front-rear direction, and the horizontal direction.

  Thus, since the drive mechanism 60 can be fixed using the assembly work of the upper frame 22a and the vertical frame 22c of the frame 22, the fixing work can be easily and efficiently performed.

  In addition, the holder 66 is restricted from moving in the vertical and forward / backward directions with respect to the frame 22 by the horizontal piece 44a of the support bracket 44, and is also restricted from moving in the horizontal direction with respect to the frame 22 by the ribs 22e of the vertical frame 22c. 66 itself can be fixed in the vertical frame 22c without screwing, and the fixing operation can be made easier and more efficient.

  However, regarding the restriction in the left and right direction, instead of using the rib 22e, for example, the holder 66 is sandwiched between a pair of plates of the frame 22 (for example, a pair of inner plates 22c1 and 22c2 (see FIG. 6) of the vertical frame 22c). You may control the movement of the left-right direction.

  Further, the opening of the holder 66 is formed so as to penetrate in the vertical direction, the vertical piece 44b of the support metal fitting 44 is inserted into the opening to restrict the movement in the left-right and front-rear directions, and the groove of the holder 66 is formed in the horizontal direction. In addition, ribs formed in the horizontal direction may be inserted into the frame 22 to restrict the vertical movement.

  Further, since the horizontal piece 44a or the vertical piece 44b of the support fitting 44 penetrates the holder 66 and is in contact with the ceiling surface 66f or the side wall inner surface of the holder 66, the strength of the holder 66 is reinforced by the support fitting 44. be able to.

  In the drive device configured as described above, the driven portion that is attracted to the operating portion 32 by a magnetic force by operating the operating portion 32 on the glass plate 12 and moving it vertically along the guide portion 38. 34 moves in the up-down direction, and the transmission shaft 36 screwed with it is driven to rotate. The rotation of the transmission shaft 36 is transmitted to the first gear 62 connected so as to rotate integrally therewith, and the rotation of the first gear 62 is transmitted to the second gear 64 engaged therewith. The rotation of the second gear is transmitted to the rotating shaft 24 connected to rotate integrally with the second gear, so that the rotating shaft 24 is driven to rotate, and the ladder tape 28 is tilted to rotate the slat 26. Thereby, the inclination angle of the slat 26 can be changed.

  In the above embodiment, the driving device performs driving for changing the inclination angle of the slat 26. However, the driving device is not limited to this. It can also be set as the drive device for this.
