Therefore, in the state where the motor fixing plate 30 is engaged with the engaging portions 11m and 12m of the side wall portions 11 and 12, the male screw 22 and the above-mentioned nut screwed to the male screw 22 are engaged with the engaging portions 11m and 12m. The lower holding pieces 111d and 112d are sandwiched and attached to the side wall portions 11 and 12.

Further, on the upper surface (direction of arrow e) of the base portion 31, a recessed motor support portion 32 having no edge only on the side facing the other motor fixing plate 30 is formed. Both sides of the motor 26 in the left-right direction (arrow ab direction) are fitted and supported by the motor support portions 32 of the pair of motor fixing plates 30a and 30b.

<Installation and removal (detachment) of the motor>
In the head box 1 of the present embodiment having the above-described configuration, the operation of attaching the motor 26 and the operation of removing the motor 26 (both operations are generally referred to as “detachment”) will be described with reference to FIGS. 7 to 10.

First, the pair of motor fixing plates 30a and 30b are oriented so that the edgesless sides of the recess of the motor support portion 32 face each other, and as described above, from one end of the headbox body 10 in the longitudinal direction.

The head box 1 is attached to the window frame via the bracket B, and the blind device 100 is erected on the window frame. A total of three rudder cords 4 and an elevating cord behind them are hung from the headbox 1 at predetermined intervals in the longitudinal direction (arrow ab direction).

The elevating cord 7 is wound up by the take-up drums 21, 25, 27, and is drawn out (hanged down). That is, the rotational power of the motor 26 rotates the take-up drums 21, 25, 27 via the shaft 28, and the elevating cord is taken up or unwound. Further, when winding the elevating cord, the slat 6 starts to be wound after the front side d is most inclined upward and the rear side c is most inclined downward, and conversely, when the elevating cord is unwound. The slat 6 is started to be fed after the front side d is most inclined downward and the rear side c is most inclined upward. Then, after the bottom rail 5 is stopped at a desired position, the motor 26 is appropriately rotated in the reverse rotation direction by an appropriate amount, so that the tilt angle of the slats 6 is appropriately adjusted.

In the blind device of the present embodiment as described above, the head box 1 is removed from the window frame at the time of regular maintenance of the motor 26, and also when the motor 26 needs to be repaired or replaced due to a failure. The motor 26 can be easily attached and detached without disassembling the inside of the head box 1.

The headbox and the solar shading device of the present invention have been described with reference to preferred embodiments, but the headbox and the solar shading device of the present invention are not limited to the configuration of the above embodiment. For example, in the above embodiment of the head box, an example is given in which the motor 26 is arranged near the center of the head box 10 in the longitudinal direction (arrow ab direction) and is connected to the shaft 28 via couplings 29 on both sides thereof. However, a mode in which the motor is arranged near one end of the head box in the longitudinal direction (arrow ab direction) and is connected to one shaft 28 via one coupling on the side opposite to the end side. It doesn't matter.

Further, in the above embodiment of the head box, regarding the engagement between the engaging portion of the main body of the head box and the engaged portion of the motor fixing member, the engaging portions 11m and 12m having a specific shape and the engaged portion are engaged. The combination of 33 and 35 is given as an example, but the shapes of both are not limited to this. There is no particular limitation as long as the engaging portion of the main body of the head box and the engaged portion of the motor fixing member can be engaged with each other, but while the engaging portion and the engaged portion are engaged, It is preferable that the motor fixing member has a structure capable of sliding in the longitudinal direction of the main body of the head box.

In the example of the present embodiment, for example, the lower holding pieces 111d and 112d including the protruding portions 111ds and 112ds and the claw portions 111dt and 112dt on the head box body 10 side and the motor fixing having a shape engaged with the lower holding pieces 111d and 112d. In the combination of the lower surfaces 33b and 35b and the engaged protrusions 33p and 35p on the plate 30 side, the engaging portion having no claws 111dt and 112dt and the engaging portion having no space under the lower surfaces 33b and 35b are engaged. It may be a combination with the joint part. That is, instead of the lower holding pieces 111d and 112d, those having the same shape as the upper holding pieces 111u and 112u are arranged, and a rail-shaped engaging portion in which the two ribs face each other and a cube fitted between them. It may be a combination with the fitted portion of the shape. Even in this case, the motor fixing member can slide in the longitudinal direction of the main body of the head box while the engaging portion and the engaged portion are engaged.

Further, in the above-described embodiment of the head box, a configuration in which a pair of motor fixing plates 30, that is, two motor fixing plates 30 are arranged has been described as an example, but in the present invention, the motor fixing members may be only one or three. It does not have to be the above, and it does not have to be a plate-shaped object. For example, the motor is supported by only one motor fixing member and supported by the main body of the head box, or one side of the motor in the longitudinal direction of the head box is supported by the motor fixing member according to the present invention while the other side. The present invention can be configured with only one motor fixing member, such as being supported by a member fixed to the main body of the head box or a member integrated with the main body of the head box.
