In other words, the embodiment can cope with both of the above-described parts by designing the winding shaft support 20 and the tilt support 30 as one unit, so versatility is enhanced.

The interior space of the headbox 11 is limited in space. Suppose that the winding shaft support 20 can be attached to and detached from the tilt support 30 from the left and right directions. In this case, for example, when an operator attaches the winding shaft support 20 to the tilt support 30 during product assembly, the winding shaft support 20 may interfere with other members, making it difficult to perform the mounting work. . Moreover, when an operator removes the winding shaft support 20 from the tilt support 30 during maintenance, the winding shaft support 20 may interfere with other members, making the removal work difficult.
If the winding shaft support 20 is vertically attachable to and detachable from the tilt support 30 as in the embodiment, it is possible to suppress such deterioration in workability.

In some conventional support members, the configuration for operating the ladder cords and the configuration for operating the lifting cords are unitized (hereinafter referred to as the first configuration). Further, some conventional support members include, for example, a case that holds only the tilt drum (hereinafter referred to as a second configuration). Furthermore, in a conventional horizontal blind, a support member having a winding shaft arranged symmetrically with respect to the ladder cord of the first configuration may be mounted (hereinafter referred to as a third configuration).

A horizontal blind may have a portion where a ladder cord and a lifting cord are provided in parallel on a slat, or a portion where only a ladder cord is provided on a slat. In this case, one or both of the support members of the first configuration and the third configuration are used for the horizontal blind.
In addition, the horizontal blind may have not only places where the ladder cords and the lifting cords are provided in parallel on the slats, but also places where only the ladder cords are provided on the slats. In this case, one or both of the support members of the first configuration and the third configuration and the support member of the second configuration are used for the horizontal blind.
Thus, support members with various configurations (eg, first to third configurations) are required according to the structure of the horizontal blind. In other words, it is difficult to reuse conventional support members for horizontal blinds according to the structure of the horizontal blind, and manufacturers of support members must prepare support members with various configurations according to the structure of the horizontal blind. There is

In the embodiment, the tilt support 30 can arrange the winding shaft support 20 symmetrically. In other words, the arrangement of the winding shaft support 20 when the winding shaft support 20 is engaged with the first engaging portion ps1 and the winding shaft support 20 when engaging with the second engaging portion ps2. The arrangement of the winding shaft support 20 at this time is symmetrical in the axial direction of the winding shaft 23 . In this manner, the tilt support 30 and the winding shaft support 20 can be arranged symmetrically, so that the tilt/winding unit 1 can be improved in versatility and the number of parts can be reduced. Further, as shown in FIG. 4, the tilt/wind-up unit 1 can be used with the tilt support 30 alone, so the tilt/wind-up unit 1 is further enhanced in versatility.

In a state in which the mounting portion 21 is engaged with the first engaging portion ps1, the winding shaft support body 22 is arranged at the second engaging portion ps2. Further, in the state where the mounting portion 21 is mounted on the second engaging portion ps2, the winding shaft support body 22 is arranged on the first engaging portion ps1. That is, the take-up shaft support 20 is provided so as to overlap the tilt support 30 when the take-up shaft support 20 is attached to the tilt support 30 . Therefore, the tilt/winding unit 1 is compact.

7. Other Embodiments The tilting/winding unit 1 and the tilting unit 3 described in the embodiments can also be applied to the electric horizontal blind 10 shown in FIG. The electric horizontal blind 10 does not have an operation cord or a pulley on which the operation cord is hung, but has an electric power unit (not shown) composed of a motor or the like. The electric power unit is mounted inside the head box 11 and can drive the elevation shaft and the tilt shaft.
