## Abstract

A shade roller apparatus is provided to achieve stable attachment of a pull bar to a shading sheet, and reduce the numbers of components and process steps required for the attachment. The pull bar may include a clip portion clipping a front hem of the shading sheet along an entire length of the pull bar, and a bottom wall below the clip portion. While having a front end retained by the clip portion, the shading sheet can wrapped around the pull bar such that the shading sheet sequentially passes over an upper surface and a front surface of the clip portion and then continues along the bottom wall.

## Claims

### Claim 1

A shade roller apparatus comprising:
a shading sheet;
a roller around which the shading sheet can be rolled and from which the shading sheet can be unrolled; and
a pull bar attached to a front edge of the shading sheet, the front edge located forward in a direction in which the shading sheet is unrolled,
the shade roller apparatus configured to open and close a window provided in a roof of a vehicle with the shade sheet,
wherein the pull bar includes a clip portion and a bottom wall below the clip portion,
the clip portion includes an upper clip part and a lower clip part which are opened and closed with an end of each of the upper and lower clip parts functioning as a living hinge pivot, such that the upper and lower clip parts clip the front edge of the shading sheet therebetween along an entire length of the pull bar, and
while having a front end retained by the clip portion, the shading sheet is wrapped around the pull bar such that the shading sheet continues along the upper clip part, the pivot, and the bottom wall, and then extends to the roller.

### Claim 2 (depends on 1)

The shade roller apparatus of claim 1, wherein the pull bar includes a retaining part which is configured to hold and retain the shading sheet between the retaining part and a tip end of the upper clip part while the upper clip part is in a closed state.

### Claim 3 (depends on 2)

The shade roller apparatus of claim 2, wherein the upper clip part has a meshing portion on a surface facing a surface of the lower clip part, and the lower clip part has another meshing portion on the surface facing the surface of the upper clip part, and the meshing portions mesh with each other to pinch the shading sheet between the meshing portions.

### Claim 4 (depends on 1)

The shade roller apparatus of claim 1, wherein the clip portion has such dimensions that the clip portion clips and compresses the shading sheet.

### Claim 5 (depends on 1)

The shade roller apparatus of claim 1, wherein the bottom wall has, in an end portion close to the pivot, a curved portion which is curved toward the pivot, and the pivot projects forward with respect to the curved portion in a direction in which the pull bar is pulled.
