Description

車両用サンシェード装置Vehicle sunshade device
　本発明は、車両用サンシェード装置に関する。 The present invention relates to a vehicle sunshade device.
　従来、車両に設けられたウィンドウを透過して車両内に日光が入射する場合があり、このような日光を遮蔽するためのスクリーンを備える車両用サンシェード装置が知られている。 Conventionally, sunlight may enter the vehicle through a window provided in the vehicle, and a vehicle sunshade device provided with a screen for shielding such sunlight is known.
　特許文献１には、ウィンドウを開閉可能に設けられたドア本体に取り付けられる車両用サンシェード装置の例として、ドア本体に収納されて車両上方に引き上げて使用されるスクリーンと、ドア本体の上端部内側に設置されてスクリーンを巻き取る巻取装置と、を備えているものが開示されている。自動車の後席に乗る同乗者は、日光を遮蔽する必要がある場合には、スクリーンを巻取装置から引き上げてウィンドウを覆い、日光を遮蔽する必要がない場合には、スクリーンを巻取装置によって巻き取らせて収納させる。 Patent Document 1 describes, as an example of a vehicle sunshade device attached to a door body provided so as to open and close a window, a screen housed in the door body and used by pulling it upward of the vehicle, and an inside of the upper end portion of the door body. It is disclosed that it is equipped with a winding device that is installed in a windshield and winds up a screen. Passengers in the rear seats of the car pull the screen out of the winder to cover the window if they need to block the sunlight, and if they do not need to block the sunlight, the screen is pulled up by the winder. Roll it up and store it.

　ところで、この類の車両用サンシェード装置には、例えば、スクリーンの前方側の辺を構成する前辺の長さと、スクリーンの後方側の辺を構成する後辺の長さとが異なるものがある。このような長さが異なる前辺と後辺とを同一の巻取軸で巻き取ると、長さが短い方の辺の巻取が完了したときには、長さが長い方の辺が巻き取られずに残ってしまう可能性がある。このようなスクリーンの布地が巻き取られずに残る現象を回避するために、巻取軸のうち長さが長い方の辺を巻き取る部分を予めパッドで巻いて径を太く設計することも考えられる。 By the way, in this kind of vehicle sunshade device, for example, the length of the front side forming the front side side of the screen and the length of the rear side forming the rear side side of the screen are different. If the front side and the rear side having different lengths are wound on the same winding shaft, the longer side will not be wound when the winding of the shorter side is completed. There is a possibility that it will remain in. In order to avoid such a phenomenon that the cloth of the screen is not wound and remains, it is conceivable to design the winding shaft by pre-winding the portion to be wound on the longer side with a pad to increase the diameter. ..
　しかし、スクリーンは、長年、巻取軸のパッドに巻き取られて伸ばされると、経時的にたるむことも考えられる。 However, if the screen is wound and stretched by the pad of the winding shaft for many years, it is possible that the screen will sag over time.
　本発明は、かかる事情に鑑みてなされたものであり、スクリーンの中で巻取軸によって巻き取られずに残る現象を回避しつつ、スクリーンのたるみの発生を抑制することができる車両用サンシェード装置を提供することを目的とする。 The present invention has been made in view of such circumstances, and is a vehicle sunshade device capable of suppressing the occurrence of slack in the screen while avoiding the phenomenon that the screen remains unwound by the take-up shaft. The purpose is to provide.

This is the side that becomes the end to be wound when the winding shaft 27a winds up. The winding end portion 15c is arranged at the upper end of the screen main body 15.
［保持フレーム］
　図４は、車両用サンシェード装置１０を車両室内側から見た一部斜視図である。保持フレーム１６は、上方に持ち上げることにより、スクリーン本体１５をたるみなく整然と引き出すための部材であり、スクリーン本体１５の上側端末（引出側の端末）に車両前後方向に沿って設けられている。保持フレーム１６は、巻取終端部１５ｃに沿って取り付けられている。保持フレーム１６は、保持バー１６ａと、切欠部１６ｂと、を有する。 [Holding frame]
FIG. 4 is a partial perspective view of the vehicle sunshade device 10 as viewed from the vehicle interior side. The holding frame 16 is a member for pulling out the screen main body 15 in an orderly manner by lifting it upward, and is provided on an upper terminal (a terminal on the pull-out side) of the screen main body 15 along the vehicle front-rear direction. The holding frame 16 is attached along the winding end portion 15c. The holding frame 16 has a holding bar 16a and a notch 16b.
　保持バー１６ａは、例えば、車両前後方向に沿って軸が延在する棒状の部材から構成されている。
　切欠部１６ｂは、保持フレーム１６の上側端末が切り欠かれて形成されている。切欠部１６ｂの切り欠きを保持バー１６ａが跨ぐように構成されている。これにより、ドアサッシュ４の上辺部４ａに設けられたフック部材４ａ１（図２参照）に対して保持バー１６ａを引っ掛けることができる。この切欠部１６ｂは、後述するノブ１７を中央にして両側にそれぞれ配置されている。 The holding bar 16a is composed of, for example, a rod-shaped member whose shaft extends along the front-rear direction of the vehicle.
The cutout portion 16b is formed by cutting out the upper terminal of the holding frame 16. The holding bar 16a is configured to straddle the notch of the notch portion 16b.

The cutouts 16b are arranged on both sides with the knob 17, which will be described later, at the center.
［ノブ］
　ノブ１７は、保持フレーム１６の車両前後方向に沿った中央部に取り付けられている。ノブ１７は、車両室内側に臨むように保持フレーム１６に取り付けられており、スクリーン本体１５を引き出したり巻き取ったりする際の把手として機能する。ノブ１７は、スクリーン用開口６ａよりも大きな形状とされている。このため、スクリーン本体１５を巻き取る際には、スクリーン用開口６ａを通過することなく、ノブ１７が引っ掛かる。その結果、スクリーン本体１５の巻き取りが強制的に停止される。一方で、スクリーン本体１５を使用する際には、ドアトリム３の上端部に位置するノブ１７を上方に持ち上げることで、スクリーン本体１５を引き出すことができる。 [Knob]
The knob 17 is attached to the central portion of the holding frame 16 along the vehicle front-rear direction. The knob 17 is attached to the holding frame 16 so as to face the vehicle interior side, and functions as a handle when the screen body 15 is pulled out or wound up. The knob 17 has a shape larger than the screen opening 6a. Therefore, when the screen body 15 is wound up, the knob 17 is caught without passing through the screen opening 6a. As a result, the winding of the screen body 15 is forcibly stopped. On the other hand, when using the screen body 15, the screen body 15 can be pulled out by lifting the knob 17 located at the upper end of the door trim 3 upward.
［巻取部］
　図５は、車両用サンシェード装置１０のスクリーン１４及び予備巻き固定部２７ｂの展開図である。この図５及び前述の図４を参照しつつ以下説明する。巻取部２７は、車両の内側を覆う内装トリムの裏面側に配置され、スクリーン１４を巻き取る部位である。巻取部２７は、巻取軸２７ａと、予備巻き固定部２７ｂと、を有する。 [Winding section]
FIG. 5 is a developed view of the screen 14 and the preliminary winding fixing portion 27b of the vehicle sunshade device 10. This will be described below with reference to FIG. 5 and FIG. 4 described above. The winding portion 27 is arranged on the back surface side of the interior trim that covers the inside of the vehicle, and is a portion for winding the screen 14. The winding portion 27 has a winding shaft 27a and a preliminary winding fixing portion 27b.
［巻取軸］
　巻取軸２７ａは、後述の予備巻き固定部２７ｂが巻かれて固定された状態で、スクリーン１４を巻くための軸として機能する。巻取軸２７ａは、スクリーン１４が引っ張られていないときにはスクリーン１４を巻取可能に保持している。これとは反対に、巻取軸２７ａは、スクリーン１４が引っ張られることによりスクリーン１４を展開可能に保持している。また、巻取軸２７ａは、例えばシリンダーで形成されており、内部にスクリーン１４を巻き取るための図示しないスプリングが内蔵されている。 [Take-up shaft]
The take-up shaft 27a functions as a shaft for winding the screen 14 in a state where the preliminary winding fixing portion 27b, which will be described later, is wound and fixed. The take-up shaft 27a holds the screen 14 so that it can be taken up when the screen 14 is not pulled. On the contrary, the take-up shaft 27a holds the screen 14 in a deployable manner by pulling the screen 14. Further, the take-up shaft 27a is formed of, for example, a cylinder, and has a built-in spring (not shown) for winding the screen 14.
［予備巻き固定部］
　予備巻き固定部２７ｂは、スクリーン１４から巻取軸２７ａの方へと延設された領域であって巻取軸２７ａに予め巻かれて固定される。予備巻き固定部２７ｂは、巻取始端部１５ｄと、第１縁部１１５ａと、第２縁部１１５ｂと、固定始端１１５ｃと、によって囲まれた領域の部分である。本実施形態では、台形状に形成されている。予備巻き固定部２７ｂが巻取軸２７ａに巻かれる量は、第１辺１５ａ側から第２辺１５ｂ側へと次第に多く設定されている。第１縁部１１５ａと巻取始端部１５ｄとの間の巻き寸法は、例えば第１辺１５ａ側の寸法Ｋ１と第２辺１５ｂ側の寸法Ｋ２とを比べると、第２辺１５ｂ側の寸法Ｋ２の方が第１辺１５ａ側の寸法Ｋ１よりも大きく設定されている。 [Preliminary winding fixing part]
The preliminary winding fixing portion 27b is a region extending from the screen 14 toward the winding shaft 27a, and is previously wound and fixed to the winding shaft 27a. The pre-winding fixing portion 27b is a portion of a region surrounded by the winding start end portion 15d, the first edge portion 115a, the second edge portion 115b, and the fixing start end 115c. In this embodiment, it is formed in a trapezoidal shape. The amount of the preliminary winding fixing portion 27b wound around the winding shaft 27a is gradually set to increase from the first side 15a side to the second side 15b side. The winding dimension between the first edge portion 115a and the winding start end portion 15d is, for example, the dimension K2 on the second side 15b side when comparing the dimension K1 on the first side 15a side and the dimension K2 on the second side 15b side. Is set to be larger than the dimension K1 on the first side 15a side.
　第１縁部１１５ａは、第１辺１５ａの一端部１５ａ１から巻取軸２７ａに向かうに従って第１辺１５ａ側から第２辺１５ｂ側へと近づく部分である。本実施形態では、第１縁部１１５ａは、線で形成されている。第２縁部１１５ｂは、第２辺１５ｂの一端部１５ｂ１と巻取軸２７ａとを結ぶ部分である。第２縁部１１５ｂは、第２辺１５ｂを巻取軸２７ａへと延長した線部分に相当する。第１縁部１１５ａの長さは、第２縁部１１５ｂの長さよりも長く設定されている。 The first edge portion 115a is a portion that approaches from the first side 15a side to the second side 15b side as it goes from one end portion 15a1 of the first side 15a toward the winding shaft 27a. In the present embodiment, the first edge portion 115a is formed by a line. The second edge portion 115b is a portion connecting one end portion 15b1 of the second side 15b and the winding shaft 27a. The second edge portion 115b corresponds to a line portion extending the second side 15b to the winding shaft 27a. The length of the first edge portion 115a is set to be longer than the length of the second edge portion 115b.
　固定始端１１５ｃは、スクリーン１４が巻取軸２７ａに固定される始端となる部分である。固定始端１１５ｃの部分は、巻取軸２７ａに固定されている。スクリーン本体１５と巻取軸２７ａとの間の予備巻き固定部２７ｂについては、固定始端１１５ｃの部分は直接的に巻取軸２７ａに固定されているが、固定始端１１５ｃ以外の第１縁部１１５ａの部分は直接的に巻取軸２７ａに固定されていない。従って、第１縁部１１５ａと巻取軸２７ａとの間は、布地が無い領域となっている。固定始端１１５ｃは、第１辺１５ａよりも第２辺１５ｂに近い。 The fixed start end 115c is a portion where the screen 14 is fixed to the take-up shaft 27a. The portion of the fixed starting end 115c is fixed to the take-up shaft 27a. Regarding the preliminary winding fixing portion 27b between the screen main body 15 and the winding shaft 27a, the portion of the fixed starting end 115c is directly fixed to the winding shaft 27a, but the first edge portion 115a other than the fixed starting end 115c Is not directly fixed to the take-up shaft 27a. Therefore, the area between the first edge portion 115a and the take-up shaft 27a is a region without fabric. The fixed starting end 115c is closer to the second side 15b than the first side 15a.
　固定始端１１５ｃは、辺であるので、点である場合に比べて巻き易い。例えば、固定始端１１５ｃが辺であると、この固定始端１１５ｃを巻取始端部１５ｄと平行に巻いていけば良いので、予備巻き固定部２７ｂを巻き易い。しかし、固定始端１１５ｃが点であって予備巻き固定部２７ｂが逆三角形である場合には、巻取軸２７ａが巻取始端部１５ｄと平行になるように予備巻き固定部２７ｂを巻いていこうとしても、巻取軸２７ａが巻取始端部１５ｄに平行に配置されない場合には、巻取軸２７ａを巻取始端部１５ｄに揃え難い場合もあり、予備巻き固定部２７ｂを巻き難い。第１縁部１１５ａの先端１１５ａ１と第２縁部１１５ｂの先端１１５ｂ１とを結んだ固定始端１１５ｃの寸法Ｘ３は、巻取始端部１５ｄの寸法Ｘ２よりも小さく設定されている。 Since the fixed starting end 115c is a side, it is easier to wind than when it is a point. For example, if the fixed start end 115c is a side, the fixed start end 115c may be wound in parallel with the winding start end portion 15d, so that the preliminary winding fixing portion 27b can be easily wound. However, when the fixed start end 115c is a point and the preliminary winding fixing portion 27b is an inverted triangle, the preliminary winding fixing portion 27b is attempted to be wound so that the winding shaft 27a is parallel to the winding starting end portion 15d. However, if the take-up shaft 27a is not arranged parallel to the take-up start end portion 15d, it may be difficult to align the take-up shaft 27a with the take-up start end portion 15d, and it is difficult to wind the preliminary winding fixing portion 27b. The dimension X3 of the fixed start end 115c connecting the tip 115a1 of the first edge portion 115a and the tip 115b1 of the second edge portion 115b is set smaller than the dimension X2 of the winding start end 15d.
　図６（ａ）は、予備巻き固定部２７ｂを巻いた状態の車両用サンシェード装置１０の内側面図である。図６（ａ）に示されるように、巻取始端部１５ｄの寸法Ｘ２は、巻取終端部１５ｃの寸法Ｘ１よりも大きい。 FIG. 6A is an inner side view of the vehicle sunshade device 10 in a state where the preliminary winding fixing portion 27b is wound. As shown in FIG. 6A, the dimension X2 of the winding start end portion 15d is larger than the dimension X1 of the winding end portion 15c.
　図６（ｂ）は、車両用サンシェード装置１０の巻取軸２７ａを上方から見た断面図である。図６（ｂ）に示されるように、巻取軸２７ａに対して予備巻き固定部２７ｂが巻き取られて固定された段階で、巻取部２７の径は、第１辺１５ａ側から第２辺１５ｂ側へと次第に太く設定されている。すなわち、巻取部２７における車両後方の径が細く設定され、巻取部２７における車両前方の径が太く設定され、その間の変化はなだらかに変化する。
　これは、予備巻き固定部２７ｂについては、車両後方側の巻き量が少ないので細い径が形成され、車両前方側の巻き量が多いので太い径が形成されるからである。また、巻き量は、車両後方側から車両前方側に向かうに従って次第に多くなるので、巻取部２７の径は車両後方側から車両前方側に向かうに従って次第に大きくなる。 FIG. 6B is a cross-sectional view of the take-up shaft 27a of the vehicle sunshade device 10 as viewed from above. As shown in FIG. 6B, when the preliminary winding fixing portion 27b is wound and fixed to the winding shaft 27a, the diameter of the winding portion 27 is the second from the first side 15a side. It is gradually thickened toward the side 15b side. That is, the diameter at the rear of the vehicle in the winding unit 27 is set to be small, the diameter at the front of the vehicle at the winding unit 27 is set to be large, and the change between them changes gently.
This is because the preliminary winding fixing portion 27b has a small diameter because the winding amount on the rear side of the vehicle is small, and a large diameter because the winding amount on the front side of the vehicle is large. Further, since the winding amount gradually increases from the rear side of the vehicle toward the front side of the vehicle, the diameter of the winding portion 27 gradually increases from the rear side of the vehicle toward the front side of the vehicle.
［パッド］
　また、その上で、巻取部２７の車両前方側にパッド１９が固定される。パッド１９の厚みの分だけ巻取部２７は段差を有することになる。このため、巻取始端部１５ｄは、スクリーン本体１５が巻取軸２７ａによって巻き取られた後に、巻取終端部１５ｃと略平行な位置に到達する。そして、パッド１９の部分は、保持フレーム１６の前端に揃えられる。パッド１９は、巻取軸２７ａに巻かれた予備巻き固定部２７ｂのうち、「第２辺１５ｂの位置」から「第２辺１５ｂから所定寸法の位置」までの範囲に巻かれる。ここでいう所定寸法とは、例えば、前述した固定始端１１５ｃの寸法Ｘ３であっても良い。 [pad]
On top of that, the pad 19 is fixed to the front side of the vehicle of the winding unit 27. The winding portion 27 has a step by the thickness of the pad 19. Therefore, the winding start end portion 15d reaches a position substantially parallel to the winding end portion 15c after the screen main body 15 is wound by the winding shaft 27a. Then, the portion of the pad 19 is aligned with the front end of the holding frame 16. The pad 19 is wound in a range from "the position of the second side 15b" to "the position of the second side 15b to a predetermined dimension" in the preliminary winding fixing portion 27b wound around the winding shaft 27a. The predetermined dimension referred to here may be, for example, the dimension X3 of the fixed start end 115c described above.
［巻取ユニット］
　ここで、図４に戻って説明する。図４に示されるように、巻取ユニット２０は、リトラクタ２１と、ベアリング２４と、を有する。リトラクタ２１は、巻取部２７をドアアッパー６に取り付けると共に、ベアリング２４及び巻取軸２７ａを支持するための部材である。ベアリング２４は、巻取軸２７ａの両端を支持しつつ巻取軸２７ａと共に回転する。 [Taking unit]
Here, it will be described back to FIG. As shown in FIG. 4, the take-up unit 20 has a retractor 21 and a bearing 24. The retractor 21 is a member for attaching the take-up portion 27 to the door upper 6 and supporting the bearing 24 and the take-up shaft 27a. The bearing 24 rotates together with the take-up shaft 27a while supporting both ends of the take-up shaft 27a.
［製造工程］
　車両用サンシェード装置１０が製造される工程では、図５のように予備巻き固定部２７ｂが展開された状態から、図６（ａ）のように予備巻き固定部２７ｂが巻取軸２７ａに巻かれた状態に移行させる。そして、巻取軸２７ａの位置と巻取始端部１５ｄの位置とが揃えられ、巻取軸２７ａに対して予備巻き固定部２７ｂが固定される。それから、図３に示されるように、巻取軸２７ａの外周にパッド１９が取り付けられる。 [Manufacturing process]
In the process of manufacturing the vehicle sunshade device 10, the preliminary winding fixing portion 27b is wound around the winding shaft 27a as shown in FIG. 6A from the state where the preliminary winding fixing portion 27b is deployed as shown in FIG. Move to the new state. Then, the position of the take-up shaft 27a and the position of the take-up start end portion 15d are aligned, and the preliminary winding fixing portion 27b is fixed to the take-up shaft 27a. Then, as shown in FIG. 3, a pad 19 is attached to the outer circumference of the take-up shaft 27a.
［使用方法］
　自動車の後席に乗っている同乗者は、ノブ１７を把持してスクリーン１４を上方に引き上げる。そして、同乗者は、切欠部１６ｂと保持バー１６ａにより形成される孔を、ドアサッシュ４の上辺部４ａに設けられたフック部材４ａ１（図２参照）に引っ掛ける。 [how to use]
A passenger in the rear seat of the car grips the knob 17 and pulls up the screen 14. Then, the passenger hooks the hole formed by the notch portion 16b and the holding bar 16a on the hook member 4a1 (see FIG. 2) provided on the upper side portion 4a of the door sash 4.
　本実施形態の車両用サンシェード装置１０は、第１辺１５ａ、及び第１辺１５ａに対向して配置され第１辺１５ａよりも長い第２辺１５ｂを有し、車両に設けられたウィンドウ５に沿って展開可能なスクリーン１４と、車両の内側を覆う内装トリムの裏面側に配置されてスクリーン１４を巻取可能な巻取軸２７ａ、及びスクリーン１４から延設されて巻取軸２７ａに予め巻かれて固定される予備巻き固定部２７ｂを有する巻取部２７と、を備える。ここで、予備巻き固定部２７ｂが巻取軸２７ａに巻かれる量は、第１辺１５ａ側から第２辺１５ｂ側へと次第に多く、前記巻取部２７の径は、第１辺１５ａ側から第２辺１５ｂ側へと次第に太く設定されている。
　こうした構成によれば、巻取部２７の径が第１辺１５ａ側から第２辺１５ｂ側へと次第に太く設定されているので、スクリーン１４の長い方の辺である第２辺１５ｂが巻き取られずに残る現象が回避される。また、予備巻き固定部２７ｂが巻取軸２７ａに巻かれる量が第１辺１５ａ側から第２辺１５ｂ側へと次第に多く設定されているので、スクリーン１４のたるみの発生が抑制される。その結果、スクリーン１４の中で巻取軸２７ａによって巻き取られずに残る現象が回避されつつ、スクリーン１４のたるみの発生が抑制される。 The vehicle sunshade device 10 of the present embodiment has a first side 15a and a second side 15b that is arranged to face the first side 15a and is longer than the first side 15a, and is provided in a window 5 provided on the vehicle. A screen 14 that can be deployed along the screen, a take-up shaft 27a that is arranged on the back side of the interior trim that covers the inside of the vehicle and can take up the screen 14, and a take-up shaft 27a that extends from the screen 14 and is pre-wound on the take-up shaft 27a. A winding portion 27 having a preliminary winding fixing portion 27b to be fixed by being fastened is provided. Here, the amount of the preliminary winding fixing portion 27b wound around the winding shaft 27a gradually increases from the first side 15a side to the second side 15b side, and the diameter of the winding portion 27 is from the first side 15a side. It is gradually thickened toward the second side 15b side.
According to such a configuration, the diameter of the winding portion 27 is gradually increased from the first side 15a side to the second side 15b side, so that the second side 15b, which is the longer side of the screen 14, is wound. The phenomenon that remains without being left is avoided. Further, since the amount of the preliminary winding fixing portion 27b wound around the winding shaft 27a is gradually set from the first side 15a side to the second side 15b side, the occurrence of slack in the screen 14 is suppressed. As a result, the occurrence of slack in the screen 14 is suppressed while avoiding the phenomenon that the screen 14 remains unwound by the take-up shaft 27a.
　また、車両用サンシェード装置１０は、巻取軸２７ａに巻かれた予備巻き固定部２７ｂのうち、第２辺１５ｂの位置から第２辺１５ｂから所定寸法の位置までの範囲に巻かれるパッド１９を更に備える。こうした構成によれば、パッド１９がスクリーン１４を巻き取る分、予備巻き固定部２７ｂの巻取り面積を広く設定せずに済む。
　また、巻取軸２７ａに対してパッド１９を先に取り付けてから予備巻き固定部２７ｂを巻くことも考えられるが、パッド１９に対して予備巻き固定部２７ｂが確実に固定された状態にしないと、予備巻き固定部２７ｂ全体としてはたるみが生じ易くなる可能性がある。あるいは、パッド１９の上から予備巻き固定部２７ｂを巻くと、作業者によってはパッド１９を潰しながら巻取軸２７ａに巻く人やパッド１９を潰さずに巻取軸２７ａに巻く人が出てくるが、このような作業者の力加減による製品のバラツキが生じ易くなる可能性がある。そのために、巻取軸２７ａに対してパッド１９を先に取り付けてから予備巻き固定部２７ｂを巻く方が良いと考えられる。
　なお、予備巻き固定部２７ｂとパッド１９とを兼用することにより、パッド１９を小さく形成しても機能できる。このために、巻取部２７の段差を小さく設計することができ、スクリーン１４のたるみが抑制される。 Further, the vehicle sunshade device 10 has a pad 19 wound in a range from the position of the second side 15b to the position of the second side 15b to a predetermined dimension among the preliminary winding fixing portions 27b wound around the winding shaft 27a. Further prepare. According to such a configuration, it is not necessary to set a large winding area of the preliminary winding fixing portion 27b because the pad 19 winds the screen 14.
Further, it is conceivable to attach the pad 19 to the take-up shaft 27a first and then wind the preliminary winding fixing portion 27b, but the preliminary winding fixing portion 27b must be securely fixed to the pad 19. , There is a possibility that slack is likely to occur as a whole of the preliminary winding fixing portion 27b. Alternatively, when the preliminary winding fixing portion 27b is wound from above the pad 19, some workers wind the pad 19 around the winding shaft 27a while crushing the pad 19 or wind the pad 19 around the winding shaft 27a without crushing the pad 19. However, there is a possibility that the product may easily vary due to the force of the operator. Therefore, it is considered better to attach the pad 19 to the take-up shaft 27a first and then wind the preliminary winding fixing portion 27b.
By using the preliminary winding fixing portion 27b and the pad 19 in combination, the pad 19 can function even if it is made small. Therefore, the step of the winding portion 27 can be designed to be small, and the slack of the screen 14 is suppressed.
