  As a connection structure between the drawer end portion of the shade fabric and the garnish in Patent Document 1, a bag portion along the width direction is formed at the drawer end portion of the shade fabric, and a core bar is inserted into the bag portion. The bag portion in which the core rod is inserted is configured to be connected to each other by being slid into a shade holding groove portion in the length direction provided in a garnish made of an extrusion mold.

  Similarly, the connecting structure of the curtain drawing end and the garnish in Patent Document 2 and Patent Document 3 also forms a bag portion along the width direction at the curtain drawing end portion, and the bag portion has a core. The bag portion in which the rod is inserted and the core rod is inserted is slid and inserted into the curtain holding groove in the length direction provided in the garnish made of the extrusion mold material.

  Therefore, although there is an advantage that they can be easily assembled with each other by slide insertion, one shade fabric or curtain is a thin sheet, and the other garnish is a thick three-dimensional shape. As a result, there is a problem in that a step is generated in the connecting portion of each other, resulting in poor design from the inside. There is also a problem that there is no means for concealing the sewn portion for forming the bag portion, and the sewn portion is visible from the room, resulting in poor design. In addition, there is no means for hiding the sewing portion for forming the bag portion, and there is a problem that the design is inferior because it can be seen from the room.

  Then, the subject which this invention tends to solve is providing the winding-type shade apparatus which aimed at the improvement of the design property, without impairing assembly property.

The technical means for solving the above-mentioned problems are a sheet-like shade fabric that is disposed inside the permeable window and is urged in the winding direction and has a drawer end, and a width direction of the drawer end. A connecting stay extending along the width direction of the connecting stay, the garnish connected to the connecting stay, and forming a shade holding portion on the connecting stay, the drawing end with respect to the shade holding portion In the winding-type shade device provided with a core rod inserted into the bag portion so as to retain and lock the bag portion formed along the width direction of the portion in a direction different from the width direction , Folded so that the shade dough extends from the indoor side end of the shade holding portion to the indoor side and close to the garnish, and the shade fabric is substantially flush with the garnish on the indoor side of the garnish. In that it comprises a turn-back piece portion of the state.

  Moreover, the sewing part for forming the bag part may be arranged between the shade holding part and the folded part of the shade fabric by the folding piece part so as not to be seen from the indoor side.

Further, ratchet ribs are alternately formed on both side portions of the hook portion of the garnish that are inserted into the garnish connection portion of the connection stay, facing the garnish connection portion, with an interval in the width direction. It is good also as a structure.

  The garnish may be integrally formed of a resin material, and the connection stay may be formed of a metal material.

  Furthermore, the said translucent window is good also as a structure which is provided in the roof part of a vehicle and can be opened and closed freely.

  According to the winding-type shade device of the present invention, a sheet-like shade fabric that is disposed inside the permeable window and is urged in the winding direction and has a pull-out end, and the width direction of the pull-out end. A connecting stay extending along the width direction of the connecting stay, the garnish connected to the connecting stay, and forming a shade holding portion on the connecting stay, the drawing end with respect to the shade holding portion In the winding-type shade device provided with a core rod inserted into the bag portion so as to prevent and lock the bag portion formed along the width direction of the portion in a direction different from the width direction, the shade fabric In order to make the garnish substantially the same surface on the indoor side, a folding piece for folding the shade fabric is extended so as to be closer to the garnish indoor surface direction than the shade holding portion. Since it is formed on the stay, when attaching the garnish to the drawer end of the shade fabric, the bag portion in which the core rod at the drawer end of the shade fabric is inserted is placed in the width direction on the shade holding portion of the connecting stay. If the garnish stay connection part is inserted into the garnish connection part of the connection stay from the width direction, the shade fabric and the garnish can be easily connected via the connection stay, and the shade cloth is shaded with the folded piece. Since the garnish and the interior surface of the garnish are arranged so as to extend from the holding portion in the garnish direction, the interior surface of the garnish and the interior surface of the shade fabric are close to each other and are substantially flush with each other. Thus, the design can be improved without impairing the assembling property.

  In addition, since the shade fabric is fixed in the folded state with the folding piece, the winding force acting on the shade fabric is biased in the winding direction so that the shade fabric is uniformly tensioned and wrinkles can be effectively prevented. .

  Furthermore, if the sewing part for forming the bag part is arranged between the shade holding part and the folded part of the shade fabric by the folding piece part so as not to be seen from the indoor side, the bag part is shaded. In the case where the end portion of the fabric is folded and sewn, there is an advantage that the sewn portion can be effectively hidden in the connecting stay by folding the shade fabric.

  Further, on both sides of the hook portion of the garnish that is inserted into the garnish connecting portion of the connecting stay, facing the garnish connecting portion, the length direction along the width direction is spaced apart and the back side is alternately rattled. If the structure is formed with ribs, it is possible to effectively prevent backlash between the connecting stay and the garnish without impairing the assembling property at the time of insertion.

  Furthermore, if the garnish is integrally formed of a resin material and the connecting stay is formed of a metal material, the rigidity (strength) of the garnish can be reinforced by the connected connecting stay, and the shape of the garnish can be changed. It can be easily formed into a desired shape, and the design can be improved from this point.

  In addition, if a translucent window is provided on the roof of the vehicle and can be opened and closed, it can be used as a sunroof device for the vehicle.
