　以下、本発明の実施形態を説明する。むろん、以下の実施形態は本発明を例示するものに過ぎず、実施形態に示す特徴の全てが発明の解決手段に必須になるとは限らない。 Hereinafter, embodiments of the present invention will be described. Of course, the following embodiments are merely examples of the present invention, and all the features shown in the embodiments are not necessarily essential to the means for solving the invention.
（１）本発明に含まれる技術の概要：
　まず、図１～１１に示される例を参照して本発明に含まれる技術の概要を説明する。尚、本願の図は模式的に例を示す図であり、これらの図に示される各方向の拡大率は異なることがあり、各図は整合していないことがある。むろん、本技術の各要素は、符号で示される具体例に限定されない。 (1) Summary of technology included in the present invention:
First, the outline of the technology included in the present invention will be described with reference to the examples shown in FIGS. In addition, the figure of this application is a figure which shows an example typically, The expansion ratio of each direction shown by these figures may differ, and each figure may not match. Of course, each element of the present technology is not limited to the specific example indicated by the reference numeral.
［比較例］
　図１０は、車両用巻取装置の製造方法の比較例として、巻取軸２の本体部分であるバレル部材１０の外周面１０ｏにシート状部材２０の本体部分２１の基端部２２を両面粘着テープ４０により接着させる様子を模式的に例示している。シート状部材２０の引出端２６にはリンフォース部材２５があり、シート状部材２０の本体部分２１はリンフォース部材２５に繋がっている。便宜上、本体部分２１の表裏について、バレル部材１０に巻かれた時に外側となる方を表側２１ａと呼び、内側となる方を裏側２１ｂと呼ぶことにする。シート状部材２０の引き出し方向Ｄ２２における両面粘着テープ４０の長さＬａは、バレル部材１０の外周長Ｌｃよりもごく僅かに短くされている。従って、本体部分２１の表側２１ａには、両面粘着テープ４０が重ならない。これは、例えば、バレル部材１０がアルミニウム製であって本体部分２１が塩化ビニル樹脂製である場合、２０～３０℃程度において、バレル部材１０と両面粘着テープ４０との接着強度は、本体部分２１と両面粘着テープ４０との接着強度よりも高いためである。本体部分２１のうちバレル部材１０の外周面１０ｏに接着する部分は、引き出し方向Ｄ２２の側の接着端２２ａから収容方向Ｄ２１の側の接着端２２ｅまでとなる。 [Comparative example]
FIG. 10 shows, as a comparative example of the method for manufacturing the vehicle winding device, the base end portion 22 of the body portion 21 of the sheet-like member 20 is adhered on both sides to the outer peripheral surface 10o of the barrel member 10 which is the body portion of the winding shaft 2. The manner of bonding with the tape 40 is schematically illustrated. The drawer end 26 of the sheet-like member 20 has a reinforcement member 25, and the main body portion 21 of the sheet-like member 20 is connected to the reinforcement member 25. For convenience, with respect to the front and back of the main body portion 21, the outer side when wound around the barrel member 10 is referred to as the front side 21a, and the inner side is referred to as the back side 21b. The length La of the double-sided pressure-sensitive adhesive tape 40 in the drawing direction D22 of the sheet-like member 20 is slightly shorter than the outer peripheral length Lc of the barrel member 10. Therefore, the double-sided adhesive tape 40 does not overlap the front side 21 a of the main body portion 21. For example, when the barrel member 10 is made of aluminum and the main body portion 21 is made of vinyl chloride resin, the adhesive strength between the barrel member 10 and the double-sided adhesive tape 40 is about 20 to 30 ° C. This is because the adhesive strength between the adhesive tape 40 and the double-sided adhesive tape 40 is higher. The portion of the main body portion 21 that adheres to the outer peripheral surface 10o of the barrel member 10 extends from the adhesive end 22a on the drawing direction D22 side to the adhesive end 22e on the accommodation direction D21 side.
　シート状部材２０の基端部２２の裏側に両面粘着テープ４０の第一粘着面４１を貼り付け、両面粘着テープ４０の第二粘着面４２を端４４、すなわち、本体部分２１の接着端２２ｅの側からバレル部材１０の外周面１０ｏに当てた状態を、図１０に示している。この状態でシート状部材２０の本体部分２１を巻くように回転軸ＡＸ１を中心としてバレル部材１０を周方向Ｄ１０へ回転させると、図１１に例示する巻取装置９０１のように、両面粘着テープ４０の第二粘着面４２がバレル部材１０の外周面１０ｏに貼り付き、シート状部材２０の基端部２２がバレル部材１０の外周面１０ｏに留められる。尚、図１０，１１に示すシート状部材２０の本体部分２１、及び、両面粘着テープ４０の厚さは、説明上の一例に過ぎない。従って、実際の本体部分２１、及び、両面粘着テープ４０の厚さは、図１０，１１に示す厚さよりも薄い等、図１０，１１に示す厚さと異なってもよい。 The first adhesive surface 41 of the double-sided pressure-sensitive adhesive tape 40 is attached to the back side of the base end portion 22 of the sheet-like member 20, and the second adhesive surface 42 of the double-sided pressure-sensitive adhesive tape 40 is the end 44, that is, the adhesive end 22 e of the main body portion 21. FIG. 10 shows a state where it is applied to the outer peripheral surface 10o of the barrel member 10 from the side. When the barrel member 10 is rotated in the circumferential direction D10 around the rotation axis AX1 so as to wind the main body portion 21 of the sheet-like member 20 in this state, the double-sided pressure-sensitive adhesive tape 40 is used as in the winding device 901 illustrated in FIG. The second adhesive surface 42 adheres to the outer peripheral surface 10 o of the barrel member 10, and the base end portion 22 of the sheet-like member 20 is fastened to the outer peripheral surface 10 o of the barrel member 10. The thickness of the main body portion 21 of the sheet-like member 20 and the double-sided pressure-sensitive adhesive tape 40 shown in FIGS. 10 and 11 is merely an example for explanation. Accordingly, the actual thickness of the main body portion 21 and the double-sided pressure-sensitive adhesive tape 40 may be different from the thicknesses shown in FIGS. 10 and 11, such as being thinner than the thicknesses shown in FIGS.
　ここで、真夏の駐車等、車内が高温となることがある。シート状部材２０が引き出された状態の巻取装置９０１が高温となると、両面粘着テープ４０の粘着剤が軟化してバレル部材１０の外周面１０ｏとシート状部材２０の基端部２２との接着強度が低下することがある。すると、図１１に示すように、本体部分２１の接着端２２ａに引っ張られて両面粘着テープ４０の引き出し側の端４３がバレル部材１０の外周面１０ｏから剥離する可能性がある。しかし、例えば、バレル部材の外周面にシート状部材の基端部を固定する溝を形成して該溝にシート状部材の基端部を嵌め込む場合、バレル部材等の形状が複雑となり、バレル部材等の重量が増加する等、部品代の上昇に繋がる。そこで、巻取軸の外周面に対するシート状部材の接着強度を簡易な構造で向上させる技術を提供することが望まれる。 Here, the inside of the car may become hot, such as parking in midsummer. When the winding device 901 with the sheet-like member 20 pulled out becomes hot, the adhesive of the double-sided pressure-sensitive adhesive tape 40 is softened and the outer peripheral surface 10o of the barrel member 10 and the base end portion 22 of the sheet-like member 20 are bonded. The strength may decrease. Then, as illustrated in FIG. 11, the pull-out side end 43 of the double-sided pressure-sensitive adhesive tape 40 may be peeled from the outer peripheral surface 10 o of the barrel member 10 by being pulled by the adhesive end 22 a of the main body portion 21. However, for example, when a groove for fixing the base end portion of the sheet-like member is formed on the outer peripheral surface of the barrel member and the base end portion of the sheet-like member is fitted into the groove, the shape of the barrel member or the like becomes complicated, and the barrel This increases the cost of parts, such as an increase in the weight of the member. Therefore, it is desired to provide a technique for improving the adhesive strength of the sheet-like member to the outer peripheral surface of the winding shaft with a simple structure.
［態様１］
　本技術の一態様に係る車両用巻取装置は、図９等に例示するように、シート状部材２０と、該シート状部材２０を引き出し可能に巻き取るための巻取軸２と、前記シート状部材２０において前記巻取軸２に沿った基端部２２を前記巻取軸２の外周面１０ｏに接着させた両面粘着テープ４０と、を有している。前記両面粘着テープ４０が前記巻取軸２の外周面１０ｏに対して１周よりも長く巻かれて前記両面粘着テープ４０の外側粘着面５１と該両面粘着テープ４０の内側粘着面５２とが貼り付いた重なり部位５３が前記両面粘着テープ４０に形成されている。前記シート状部材２０の基端部２２が少なくとも前記重なり部位５３の外側に貼り付けられている。 [Aspect 1]

And a double-sided pressure-sensitive adhesive tape 40 in which a base end portion 22 along the winding shaft 2 is bonded to the outer peripheral surface 10o of the winding shaft 2 in the cylindrical member 20. The double-sided pressure-sensitive adhesive tape 40 is wound longer than one turn around the outer peripheral surface 10o of the winding shaft 2, and the outer side adhesive surface 51 of the double-sided pressure-sensitive adhesive tape 40 and the inner side adhesive surface 52 of the double-sided pressure-sensitive adhesive tape 40 are attached. An attached overlapping portion 53 is formed on the double-sided adhesive tape 40. The base end portion 22 of the sheet-like member 20 is attached to at least the outside of the overlapping portion 53.
　高温環境で試験を行ったところ、シート状部材２０の基端部２２が少なくとも重なり部位５３の外側に貼り付けられていると、巻取軸２の外周面１０ｏに対するシート状部材２０の基端部２２の接着強度が飛躍的に向上することが判った。これは、重なり部位５３において外側の両面粘着テープ４０と内側の両面粘着テープ４０とが強固に貼り付いているため、外側となる両面粘着テープ４０の引き出し側の端４３が本体部分２１の接着端２２ａに引っ張られても内側の両面粘着テープ４０に引き留められるためと考えられる。 When the test is performed in a high temperature environment, when the base end portion 22 of the sheet-like member 20 is attached to at least the outside of the overlapping portion 53, the base end portion of the sheet-like member 20 with respect to the outer peripheral surface 10o of the winding shaft 2 is obtained. It was found that the adhesive strength of 22 was drastically improved. This is because the outer double-sided pressure-sensitive adhesive tape 40 and the inner double-sided pressure-sensitive adhesive tape 40 are firmly attached to each other at the overlapping portion 53, so that the end 43 on the pull-out side of the double-sided pressure-sensitive adhesive tape 40 on the outer side is the adhesive end of the main body portion 21. This is considered to be because the inner side double-sided pressure-sensitive adhesive tape 40 is held even when pulled by 22a.
　また、巻取軸２の外周面１０ｏに対するシート状部材２０の接着強度を向上させるために、巻取軸２等を複雑な形状にする必要が無く、巻取軸２等の重量増加等が抑制される。従って、上記態様１は、巻取軸の外周面に対するシート状部材の基端部の接着強度を簡易な構造で向上させた車両用巻取装置を提供することができる。 Moreover, in order to improve the adhesive strength of the sheet-like member 20 with respect to the outer peripheral surface 10o of the winding shaft 2, it is not necessary to make the winding shaft 2 etc. in a complicated shape, and an increase in the weight of the winding shaft 2 or the like is suppressed. Is done. Therefore, the said aspect 1 can provide the winding device for vehicles which improved the adhesive strength of the base end part of the sheet-like member with respect to the outer peripheral surface of a winding shaft by simple structure.
　ここで、巻取装置に巻き取られるシート状部材は、スクリーン、シェード、ブラインド、等を含む概念であり、具体的には、トノカバー、サンシェード、等が含まれる。 Here, the sheet-like member wound around the winding device is a concept including a screen, a shade, a blind, and the like, and specifically includes a tonneau cover, a sunshade, and the like.
［態様２］
　前記巻取軸２の周方向Ｄ１０において、前記両面粘着テープ４０が前記シート状部材２０の基端部２２に貼り付いた部分の長さをＬａ、前記両面粘着テープ４０の重なり部位５３の長さをＬｂ、前記巻取軸２の外周長をＬｃとするとき、
　Ｌａ＜Ｌｃ＜Ｌａ＋Ｌｂ
でもよい。この態様では、シート状部材２０において両面粘着テープ４０が貼り付いた基端部２２が重ならずに両面粘着テープ４０の重なり部位５３が形成される。従って、本態様は、巻取軸の外周面に対するシート状部材の基端部の接着強度を向上させた好適な巻取装置を提供することができる。
　ここで、巻取軸２の断面の外形が円形である場合、巻取軸２の外周長Ｌｃは、巻取軸２の直径にπ（約３．１４）を乗じた長さとなる。 [Aspect 2]
In the circumferential direction D10 of the winding shaft 2, the length of the portion where the double-sided pressure-sensitive adhesive tape 40 is attached to the base end portion 22 of the sheet-like member 20 is La, and the length of the overlapping portion 53 of the double-sided pressure-sensitive adhesive tape 40 is Is Lb, and the outer peripheral length of the winding shaft 2 is Lc,
La <Lc <La + Lb
But you can. In this embodiment, the overlapping portion 53 of the double-sided pressure-sensitive adhesive tape 40 is formed without overlapping the base end portion 22 to which the double-sided pressure-sensitive adhesive tape 40 is attached in the sheet-like member 20. Therefore, this aspect can provide a suitable winding device in which the adhesive strength of the base end portion of the sheet-like member to the outer peripheral surface of the winding shaft is improved.
Here, when the outer shape of the cross section of the winding shaft 2 is circular, the outer peripheral length Lc of the winding shaft 2 is a length obtained by multiplying the diameter of the winding shaft 2 by π (about 3.14).
［態様３］
　ところで、本技術の一態様に係る製造方法は、図５，８等に例示するように、シート状部材２０、及び、該シート状部材２０を引き出し可能に巻き取るための巻取軸２を有する車両用巻取装置の製造方法であり、第一貼付工程ＳＴ１と第二貼付工程ＳＴ２を含む。前記第一貼付工程ＳＴ１では、前記シート状部材２０において前記巻取軸２に沿う基端部２２に対して、前記シート状部材２０の引き出し方向Ｄ２２において前記巻取軸２の外周よりも長い両面粘着テープ４０の第一粘着面４１を前記基端部２２からはみ出させて貼り付ける。前記第二貼付工程ＳＴ２では、前記両面粘着テープ４０の前記第一粘着面４１とは反対の第二粘着面４２の内、前記基端部２２からはみ出した第一部分４２１、及び、該第一部分４２１から連続し前記基端部２２からはみ出していない第二部分４２２を前記巻取軸２の外周面１０ｏに直接貼り付け、前記第二部分４２２から連続した残りの第三部分４２３を前記第一粘着面４１において前記基端部２２からはみ出した部分（例えばはみ出し部４１２）に貼り付ける。 [Aspect 3]
By the way, the manufacturing method which concerns on 1 aspect of this technique has the winding shaft 2 for winding up the sheet-like member 20 and this sheet-like member 20 so that extraction is possible so that it may illustrate in FIG. It is a manufacturing method of the winding device for vehicles, and includes the 1st sticking process ST1 and the 2nd sticking process ST2.

　図３は、バレル部材１０と端部材３０とシャフト部材６５とプレート部材６４とを例示している。図４は、別の角度から端部材３０とバレル部材１０とを例示している。
　バレル部材１０は、両端が開口した筒状部材であり、ケース部材６１内において長手方向（軸方向Ｄ１）に沿った回転軸ＡＸ１を中心として回転可能に配置される。図２に示すように、バレル部材１０の両端部１１には、端部材３０が取り付けられている。ここで、一方の端部１１ａの開口１２に端部材３０Ａが嵌入され、他方の端部１１ｂの開口１２に端部材３０Ｂが嵌入されている。尚、端部１１ａ，１１ｂを端部１１と総称し、端部材３０Ａ，３０Ｂを端部材３０と総称する。また、バレル部材１０の中空部１０ｈには、スライド部材７２が挿入されている。 FIG. 3 illustrates the barrel member 10, the end member 30, the shaft member 65, and the plate member 64.

The barrel member 10 is a cylindrical member that is open at both ends, and is disposed in the case member 61 so as to be rotatable about a rotation axis AX1 along the longitudinal direction (axial direction D1). As shown in FIG. 2, end members 30 are attached to both end portions 11 of the barrel member 10. Here, the end member 30A is inserted into the opening 12 of one end 11a, and the end member 30B is inserted into the opening 12 of the other end 11b.

A slide member 72 is inserted into the hollow portion 10 h of the barrel member 10.
　回転軸ＡＸ１に対して垂直な断面におけるバレル部材１０の外周面１０ｏの断面形状は、略円形とされている。一方、バレル部材１０の内周部１０ｉの断面形状は、非円形とされている。図４に示す内周部１０ｉには、軸方向Ｄ１に沿った溝１３が回転軸ＡＸ１を中心として６０°間隔で形成されている。バレル部材１０が押出成形品である場合、外周面１０ｏ及び内周部１０ｉは、軸方向Ｄ１の全体にわたって略同一形状となる。 The cross-sectional shape of the outer peripheral surface 10o of the barrel member 10 in a cross section perpendicular to the rotation axis AX1 is substantially circular. On the other hand, the cross-sectional shape of the inner peripheral portion 10i of the barrel member 10 is non-circular. In the inner peripheral portion 10i shown in FIG. 4, grooves 13 along the axial direction D1 are formed at intervals of 60 ° about the rotation axis AX1. When the barrel member 10 is an extruded product, the outer peripheral surface 10o and the inner peripheral portion 10i have substantially the same shape throughout the axial direction D1.
　バレル部材１０の材質には、アルミニウムといった金属、熱可塑性樹脂といった合成樹脂、等を用いることができる。アルミニウムを筒状に押し出し形成する場合のバレル部材の大きさは、特に限定されず、例えば、外径を６～３０ｍｍ程度とすることができる。 As the material of the barrel member 10, a metal such as aluminum, a synthetic resin such as a thermoplastic resin, or the like can be used. The size of the barrel member when aluminum is extruded and formed in a cylindrical shape is not particularly limited. For example, the outer diameter can be about 6 to 30 mm.
　図１，２に示すシート状部材２０の本体部分２１は、バレル部材１０の外周面１０ｏ上に巻取可能な柔軟性を有するシート状材料で形成されている。本体部分２１は、可撓性の材料が用いられ、遮光性を有する軟質材料が好ましいが、遮光率１００％の不透明材料に限定されず、半透明材料等でもよい。本体部分２１には、塩化ビニル樹脂等の樹脂材料を用いたレザー、樹脂材料を成形したシート、ジャージ素材といった伸縮性素材、織物、各種網状材料、等を用いることができる。すなわち、シート状材料の概念には網状材料等が含まれ、シート状部材の概念には網状部材等が含まれる。本体部分２１の厚さは、例えば、０．０５～２ｍｍ（より好ましくは０．１～１ｍｍ）程度とすることができる。詳細は後述するが、本体部分２１の基端部２２は、両面粘着テープ４０（図５～９参照）によりバレル部材の外周面１０ｏに留められている。本体部分２１において基端部２２とは反対側の先端縁（引出端２４）には、突出部２８，２８を有する硬質のリンフォース部材２５が取り付けられている。リンフォース部材２５は、シート状部材２０全体の引出端２６に配置されている。リンフォース部材２５には、板状の部材、棒状の部材、筒状の部材、等を用いることができ、合成樹脂の射出成形品といった成形品等を用いることができる。 1 and 2, the main body portion 21 of the sheet-like member 20 is formed of a flexible sheet-like material that can be wound on the outer peripheral surface 10 o of the barrel member 10. The main body portion 21 is made of a flexible material and is preferably a soft material having a light shielding property, but is not limited to an opaque material having a light shielding rate of 100%, and may be a translucent material or the like. For the main body portion 21, leather using a resin material such as vinyl chloride resin, a sheet formed from a resin material, a stretchable material such as a jersey material, a woven fabric, various net-like materials, and the like can be used. That is, the concept of sheet-like material includes a mesh-like material, and the concept of sheet-like member includes a mesh-like member. The thickness of the main body portion 21 can be, for example, about 0.05 to 2 mm (more preferably 0.1 to 1 mm). Although details will be described later, the base end portion 22 of the main body portion 21 is fastened to the outer peripheral surface 10o of the barrel member by a double-sided adhesive tape 40 (see FIGS. 5 to 9). A rigid reinforcement member 25 having projecting portions 28 and 28 is attached to the distal end edge (drawing end 24) of the main body portion 21 opposite to the base end portion 22. The reinforcement member 25 is disposed at the drawing end 26 of the entire sheet-like member 20. As the reinforcement member 25, a plate-shaped member, a rod-shaped member, a cylindrical member, or the like can be used, and a molded product such as an injection molded product of synthetic resin can be used.
　図３等に示す端部材３０の嵌入部３１は、バレル部材１０の端部１１の開口１２に挿入される。これにより、端部材３０の規制部３２が開口１２を隠蔽する。尚、端部材は、ローター、キャップ、等とも呼ばれる。バレル部材１０の一方の端部１１ａに取り付けられる端部材３０Ａには、軸方向外側Ｄ１ｏへ突出した軸部３０ｄが形成されている。軸部３０ｄは、ケース部材６１の端部に取り付けられたプレート部材６３の軸受け部６３ａに対して回転軸ＡＸ１を中心として回転可能に保持されている。バレル部材１０の他方の端部１１ｂに取り付けられた端部材３０Ｂには、軸方向Ｄ１へ貫通した軸受け孔３０ｃが形成されている。この軸受け孔３０ｃには、シャフト部材６５が挿入される。ケース部材６１、ホルダ６２、プレート部材６３，６４、及び、シャフト部材６５により端部材３０Ａ，３０Ｂが回転軸ＡＸ１を中心として回転可能に支持されることにより、シート状部材２０がバレル部材１０の外周面１０ｏ上に巻取可能となっている。 3 and the like, the insertion portion 31 of the end member 30 is inserted into the opening 12 of the end portion 11 of the barrel member 10. Thereby, the restriction part 32 of the end member 30 conceals the opening 12. The end member is also called a rotor, a cap, or the like. The end member 30A attached to one end portion 11a of the barrel member 10 is formed with a shaft portion 30d that protrudes outward in the axial direction D1o. The shaft portion 30d is held so as to be rotatable about the rotation axis AX1 with respect to the bearing portion 63a of the plate member 63 attached to the end portion of the case member 61. A bearing hole 30c penetrating in the axial direction D1 is formed in the end member 30B attached to the other end 11b of the barrel member 10. A shaft member 65 is inserted into the bearing hole 30c. The end member 30A, 30B is supported by the case member 61, the holder 62, the plate members 63, 64, and the shaft member 65 so as to be rotatable about the rotation axis AX1. It can be wound on the surface 10o.
　端部材３０の軸受け孔３０ｃの断面形状は、略円形とされている。嵌入部３１の外周部の各突条３３は、回転軸ＡＸ１を中心として６０°間隔で形成され、バレル部材１０の溝１３に挿入される。これにより、端部材３０は、バレル部材１０に対して回転不能に取り付けられる。端部材３０には、合成樹脂の射出成形品といった成形品等を用いることができる。 The cross-sectional shape of the bearing hole 30c of the end member 30 is substantially circular. The protrusions 33 on the outer peripheral portion of the fitting portion 31 are formed at intervals of 60 ° around the rotation axis AX1 and are inserted into the groove 13 of the barrel member 10. Thereby, the end member 30 is attached to the barrel member 10 so as not to rotate. The end member 30 may be a molded product such as a synthetic resin injection molded product.
　図１に示すケース部材６１は、シート状部材２０の本体部分２１を引き出すための引出口６１ａを有し、バレル部材１０、及び、巻き取った本体部分２１を収容する空間が形成されている。ケース部材６１の両端には、図２，３に示すプレート部材６３，６４が固定され、所定範囲内で軸方向Ｄ１へ摺動可能にホルダ６２が取り付けられている。図３に示すプレート部材６４には、シャフト部材６５の星形部６５ａが挿入される断面星形状の星形孔６４ａが形成されている。図３に示すシャフト部材６５は、断面星形状の星形部６５ａ、フランジ部６５ｂ、及び、端部材３０Ｂの軸受け孔３０ｃに挿入される本体部６５ｃを有している。本体部６５ｃの外周面の断面形状は、略円形とされている。端部材３０Ｂは、軸受け部材として機能し、回転しない本体部６５ｃに対して回転軸ＡＸ１を中心として回転可能に支持される。シャフト部材６５には、合成樹脂の射出成形品といった成形品等を用いることができる。
　むろん、シャフト部材６５とプレート部材６４との嵌合は、星形部６５ａと星形孔６４ａの組合せに限定されず、断面四角形状といった断面多角形状の部位と同様の形状の孔との組合せ等でもよい。 The case member 61 shown in FIG. 1 has an outlet 61a for pulling out the main body portion 21 of the sheet-like member 20, and a space for accommodating the barrel member 10 and the wound main body portion 21 is formed. The plate members 63 and 64 shown in FIGS. 2 and 3 are fixed to both ends of the case member 61, and holders 62 are attached to be slidable in the axial direction D1 within a predetermined range. A plate-shaped member 64 shown in FIG. 3 is formed with a star-shaped star hole 64a into which a star-shaped portion 65a of the shaft member 65 is inserted. The shaft member 65 shown in FIG. 3 has a star-shaped portion 65a having a star-shaped cross section, a flange portion 65b, and a main body portion 65c inserted into the bearing hole 30c of the end member 30B. The cross-sectional shape of the outer peripheral surface of the main body portion 65c is substantially circular. The end member 30B functions as a bearing member, and is supported to be rotatable about the rotation axis AX1 with respect to the main body portion 65c that does not rotate. The shaft member 65 may be a molded product such as a synthetic resin injection-molded product.
Of course, the fitting of the shaft member 65 and the plate member 64 is not limited to the combination of the star-shaped portion 65a and the star-shaped hole 64a, and the combination of a portion having a polygonal cross section such as a quadrangular cross section and a hole having the same shape, etc. But you can.
　回転軸ＡＸ１を中心としてバレル部材１０を回転する方向へ付勢する付勢部７０は、バレル部材１０の中空部に挿入されたばね（弾性部材）７１、及び、スライド部材７２を有する。図２に示すばね７１は、コイルばねであり、一方の端部７１ａがスライド部材７２に取り付けられ、他方の端部７１ｂがシャフト部材６５の本体部６５ｃに取り付けられている。図２に示すスライド部材７２の外周部７２ｏの各突条７２ａがバレル部材１０の溝１３に挿入されることにより、スライド部材７２は、バレル部材１０に対して、軸方向Ｄ１へは摺動可能に、且つ、相対回転不能となるように嵌合している。これにより、シート状部材２０の本体部分２１を引き出すとスライド部材７２がバレル部材１０等とともに回転してばね７１の付勢力が大きくなり、ばね７１の付勢力によりシート状部材２０の本体部分２１がバレル部材１０に巻き取られる。
　むろん、付勢部に使用可能なばねは、コイルばねに限定されず、渦巻きばね、エラストマーで形成された弾性部材、等でもよい。ばねの位置は、バレル部材の内部に限定されず、端部材よりも軸方向外側等といったバレル部材の外部でもよい。付勢部は、ばねといった弾性部材等による機械式に限定されず、電動式等でもよい。 The urging portion 70 that urges the barrel member 10 in the direction of rotation about the rotation axis AX1 includes a spring (elastic member) 71 inserted into the hollow portion of the barrel member 10 and a slide member 72. The spring 71 shown in FIG. 2 is a coil spring, and one end 71 a is attached to the slide member 72, and the other end 71 b is attached to the main body 65 c of the shaft member 65. 2 is inserted into the groove 13 of the barrel member 10, the slide member 72 can slide in the axial direction D1 with respect to the barrel member 10. As shown in FIG. And it is fitted so that relative rotation is impossible. Accordingly, when the main body portion 21 of the sheet-like member 20 is pulled out, the slide member 72 rotates together with the barrel member 10 and the like, and the urging force of the spring 71 increases, and the urging force of the spring 71 causes the main-body portion 21 of the sheet-like member 20 to move. It is wound around the barrel member 10.
Of course, the spring that can be used for the urging portion is not limited to the coil spring, but may be a spiral spring, an elastic member formed of an elastomer, or the like. The position of the spring is not limited to the inside of the barrel member, but may be the outside of the barrel member such as the outside in the axial direction from the end member.

FIG. 9 is a side view schematically illustrating the winding device 1 formed. The thicknesses of the main body portion 21 of the sheet-like member 20 and the double-sided pressure-sensitive adhesive tape 40 shown in FIGS. 5 to 9 are only examples for explanation. Accordingly, the actual thickness of the main body portion 21 and the double-sided pressure-sensitive adhesive tape 40 may be different from the thicknesses shown in FIGS. 5 to 9, such as being thinner than the thicknesses shown in FIGS. The double-sided adhesive tape is also called an adhesive double-sided tape, a double-sided adhesive tape, a double-sided tape, etc. A general-purpose product can be used for the double-sided pressure-sensitive adhesive tape 40. The thickness of the double-sided pressure-sensitive adhesive tape 40 (support 40a and pressure-sensitive adhesive layers 40b and 40c shown in FIG. 7) can be, for example, about 0.05 to 2 mm (more preferably 0.1 to 1 mm).
　本具体例でも、便宜上、本体部分２１の表裏について、バレル部材１０に巻かれた時に外側となる方を表側２１ａと呼び、内側となる方を裏側２１ｂと呼ぶことにする。 Also in this specific example, for the sake of convenience, regarding the front and back of the main body portion 21, the outer side when wound around the barrel member 10 will be referred to as the front side 21a, and the inner side will be referred to as the back side 21b.
　まず、図５に示す第一貼付工程ＳＴ１では、シート状部材２０の本体部分２１において長尺なバレル部材１０に沿う基端部２２の裏側２１ｂに対して、引き出し方向Ｄ２２においてバレル部材１０の外周（外周長Ｌｃ）よりも長い両面粘着テープ４０の第一粘着面４１を基端部２２からはみ出させて貼り付ける。図５，６には、本体部分２１の裏側２１ｂに第一粘着面４１が貼り付けられた様子が示されている。 First, in 1st sticking process ST1 shown in FIG. 5, with respect to the back side 21b of the base end part 22 in alignment with the long barrel member 10 in the main-body part 21 of the sheet-like member 20, the outer periphery of the barrel member 10 in the pull-out direction D22. The first adhesive surface 41 of the double-sided pressure-sensitive adhesive tape 40 that is longer than (peripheral length Lc) is pasted from the base end portion 22 and pasted. 5 and 6 show a state in which the first adhesive surface 41 is attached to the back side 21b of the main body portion 21. FIG.
　ここで、第一粘着面４１の内、基端部２２に貼り付いた部分を貼付部４１１と呼び、該貼付部４１１から収容方向Ｄ２１へはみ出した部分をはみ出し部４１２と呼ぶことにする。本体部分２１のうち第一粘着面４１が貼り付いた部分は、引き出し方向Ｄ２２の側の接着端２２ａから収容方向Ｄ２１の側の接着端２２ｅまでとなる。第一粘着面４１は、両面粘着テープ４０がバレル部材１０の外周面１０ｏに巻かれた時に回転軸ＡＸ１を中心として外側を向いた外側粘着面５１となる。 Here, a portion of the first adhesive surface 41 that is attached to the base end portion 22 is referred to as a sticking portion 411, and a portion that protrudes from the sticking portion 411 in the accommodation direction D21 is referred to as a protruding portion 412. The portion of the main body portion 21 to which the first adhesive surface 41 is attached extends from the adhesive end 22a on the drawing direction D22 side to the adhesive end 22e on the accommodation direction D21 side. The first pressure-sensitive adhesive surface 41 becomes an outer pressure-sensitive adhesive surface 51 facing outward with the rotation axis AX1 as the center when the double-sided pressure-sensitive adhesive tape 40 is wound around the outer peripheral surface 10o of the barrel member 10.
　また、両面粘着テープ４０の第一粘着面４１とは反対の第二粘着面４２の内、基端部２２からはみ出した部分を第一部分４２１と呼び、該第一部分４２１を除いてバレル部材１０の外周面１０ｏに直接貼り付けられる部分を第二部分４２２と呼び、該第二部分４２２から引き出し方向Ｄ２２へ連続した残りの部分を第三部分４２３と呼ぶことにする。第二粘着面４２の第二部分４２２は、第一部分４２１から引き出し方向Ｄ２２へ連続し基端部２２からはみ出していない部分である。第二粘着面４２は、両面粘着テープ４０がバレル部材１０の外周面１０ｏに巻かれた時に回転軸ＡＸ１を中心として内側を向いた内側粘着面５２となる。 In addition, the portion of the second adhesive surface 42 opposite to the first adhesive surface 41 of the double-sided adhesive tape 40 that protrudes from the base end portion 22 is referred to as a first portion 421, and the barrel member 10 is removed except for the first portion 421. A portion that is directly attached to the outer peripheral surface 10o is referred to as a second portion 422, and the remaining portion that continues from the second portion 422 in the drawing direction D22 is referred to as a third portion 423. The second portion 422 of the second adhesive surface 42 is a portion that continues from the first portion 421 in the pulling direction D22 and does not protrude from the base end portion 22. When the double-sided adhesive tape 40 is wound around the outer peripheral surface 10o of the barrel member 10, the second adhesive surface 42 becomes an inner adhesive surface 52 that faces inward with the rotation axis AX1 as the center.
　ここで、引き出し方向Ｄ２２における貼付部４１１の長さＬａが外周長Ｌｃよりも短いと、両面粘着テープ４０が貼り付いた基端部２２が重ならずに両面粘着テープ４０の重なり部位５３が形成される。この場合、両面粘着テープ４０の引き出し側の端４３が本体部分２１の接着端２２ａに引っ張られても内側の両面粘着テープ４０に引き留められるので、バレル部材１０の外周面１０ｏに対する基端部２２の接着強度が向上する。
　　Ｌａ＜Ｌｃ　…（１）
　また、第一粘着面４１に対する基端部２２の良好な粘着強度を得る点から、貼付部４１１の長さＬａは、外周長Ｌｃの１／２以上が好ましく、外周長Ｌｃの３／４以上がより好ましい。 Here, when the length La of the sticking part 411 in the pull-out direction D22 is shorter than the outer peripheral length Lc, the overlapping part 53 of the double-sided adhesive tape 40 is formed without overlapping the base end part 22 to which the double-sided adhesive tape 40 is attached. Is done. In this case, since the end 43 on the pull-out side of the double-sided pressure-sensitive adhesive tape 40 is pulled to the inner double-sided pressure-sensitive adhesive tape 40 even if it is pulled by the adhesive end 22a of the main body portion 21, the base end portion 22 of the barrel member 10 with respect to the outer peripheral surface 10o Adhesive strength is improved.
La <Lc (1)
Moreover, from the point which obtains the favorable adhesive strength of the base end part 22 with respect to the 1st adhesion surface 41, the length La of the sticking part 411 has preferable 1/2 or more of outer periphery length Lc, and is 3/4 or more of outer periphery length Lc. Is more preferable.
　さらに、引き出し方向Ｄ２２におけるはみ出し部４１２の長さＬｄと貼付部４１１の長さＬａとの和Ｌａ＋Ｌｄは、重なり部位５３を形成するために外周長Ｌｃよりも長くされる。
　　Ｌｃ＜Ｌａ＋Ｌｄ　…（２）
　はみ出し部４１２の長さＬｄ自体は、外周面１０ｏに対する基端部２２の良好な接着強度を得る点から、外周長Ｌｃの１／１０以上が好ましく、外周長Ｌｃの１／６以上がより好ましい。また、両面粘着テープ４０を節約しながら外周面１０ｏに対する基端部２２の良好な接着強度を得る点から、はみ出し部４１２の長さＬｄは、外周長Ｌｃ以下が好ましく、外周長Ｌｃの１／２以下がより好ましい。 Furthermore, the sum La + Ld of the length Ld of the protruding portion 412 and the length La of the sticking portion 411 in the pulling direction D22 is made longer than the outer peripheral length Lc in order to form the overlapping portion 53.
Lc <La + Ld (2)
The length Ld of the protruding portion 412 itself is preferably 1/10 or more of the outer peripheral length Lc, more preferably 1/6 or more of the outer peripheral length Lc, from the viewpoint of obtaining good adhesion strength of the base end portion 22 to the outer peripheral surface 10o. . In addition, the length Ld of the protruding portion 412 is preferably equal to or less than the outer peripheral length Lc from the viewpoint of obtaining good adhesive strength of the base end portion 22 with respect to the outer peripheral surface 10o while saving the double-sided adhesive tape 40, and 1 / of the outer peripheral length Lc. 2 or less is more preferable.
　基端部２２に両面粘着テープ４０の第一粘着面４１を貼り付ける際には、図７に示すように、両面粘着テープ４０の第二粘着面４２に剥離ライナー４０ｄを残してもよい。一般に、両面粘着テープ４０は、粘着剤を含む粘着剤層４０ｂ、支持体４０ａ、粘着剤を含む粘着剤層４０ｃ、及び、剥離ライナー４０ｄが順に積層された構造を有している。そこで、粘着剤層４０ｃに剥離ライナー４０ｄが貼り付いている状態で粘着剤層４０ｂの一部を基端部２２の裏側２１ｂに貼り付けると、粘着剤層４０ｃの意図しない貼り付きが抑制される。この場合、粘着剤層４０ｂが第一粘着面４１となり、粘着剤層４０ｃが第二粘着面４２となる。むろん、粘着剤層４０ｃから剥離ライナー４０ｄの一部又は全部を剥がした状態で粘着剤層４０ｃの一部を基端部２２の裏側２１ｂに貼り付けることも可能である。この場合、粘着剤層４０ｃが第一粘着面４１となり、粘着剤層４０ｂが第二粘着面４２となる。 When the first adhesive surface 41 of the double-sided pressure-sensitive adhesive tape 40 is affixed to the base end portion 22, the release liner 40d may be left on the second adhesive surface 42 of the double-sided pressure-sensitive adhesive tape 40 as shown in FIG. In general, the double-sided pressure-sensitive adhesive tape 40 has a structure in which a pressure-sensitive adhesive layer 40b containing a pressure-sensitive adhesive, a support 40a, a pressure-sensitive adhesive layer 40c containing a pressure-sensitive adhesive, and a release liner 40d are sequentially laminated. Therefore, when a part of the pressure-sensitive adhesive layer 40b is attached to the back side 21b of the base end portion 22 in a state where the release liner 40d is attached to the pressure-sensitive adhesive layer 40c, unintended sticking of the pressure-sensitive adhesive layer 40c is suppressed. . In this case, the pressure-sensitive adhesive layer 40 b becomes the first pressure-sensitive adhesive surface 41, and the pressure-sensitive adhesive layer 40 c becomes the second pressure-sensitive adhesive surface 42. Of course, a part of the pressure-sensitive adhesive layer 40c can be attached to the back side 21b of the base end portion 22 in a state where a part or all of the release liner 40d is peeled off from the pressure-sensitive adhesive layer 40c. In this case, the pressure-sensitive adhesive layer 40 c becomes the first pressure-sensitive adhesive surface 41, and the pressure-sensitive adhesive layer 40 b becomes the second pressure-sensitive adhesive surface 42.
　図８に示す第二貼付工程ＳＴ２では、まず、両面粘着テープ４０の第二粘着面４２に剥離ライナー４０ｄが貼り付いている場合には第二粘着面４２から剥離ライナー４０ｄを剥がす。第二粘着面４２が露出している状態において、図８に示すように、第二粘着面４２を端４４の側からバレル部材１０の外周面１０ｏに当てる。この状態において、基端部２２、及び、両面粘着テープ４０を巻くように回転軸ＡＸ１を中心としてバレル部材１０を周方向Ｄ１０へ回転させる。この時、第二粘着面４２の基端部２２からはみ出した第一部分４２１が外周面１０ｏに直接貼り付けられ、続く第二部分４２２が外周面１０ｏに直接貼り付けられ、続く第三部分４２３が第一粘着面４１のはみ出し部４１２に貼り付けられる。 In the second sticking step ST2 shown in FIG. 8, first, when the release liner 40d is attached to the second adhesive surface 42 of the double-sided adhesive tape 40, the release liner 40d is peeled from the second adhesive surface 42. In the state where the second adhesive surface 42 is exposed, as shown in FIG. 8, the second adhesive surface 42 is applied to the outer peripheral surface 10 o of the barrel member 10 from the end 44 side. In this state, the barrel member 10 is rotated in the circumferential direction D10 around the rotation axis AX1 so as to wind the proximal end portion 22 and the double-sided adhesive tape 40. At this time, the first portion 421 protruding from the base end portion 22 of the second adhesive surface 42 is directly attached to the outer peripheral surface 10o, the subsequent second portion 422 is directly attached to the outer peripheral surface 10o, and the subsequent third portion 423 is The first adhesive surface 41 is attached to the protruding portion 412.
　すると、図９に示すように、両面粘着テープ４０がバレル部材１０の外周面１０ｏに対して１周よりも長く巻かれて外側粘着面５１と内側粘着面５２とが貼り付いた重なり部位５３が両面粘着テープ４０に形成される。両面粘着テープ４０において、少なくとも、引き出し方向Ｄ２２の側であった端４３と収容方向Ｄ２１の側であった端４４とが重なり部位５３に含まれる。シート状部材２０の基端部２２は、少なくとも重なり部位５３の外側に貼り付いている。図９に示す基端部２２は、重なり部位５３を含む貼付部５１１の外側に貼り付いている。このようにして、基端部２２がバレル部材１０の外周面１０ｏに留められる。 Then, as shown in FIG. 9, there is an overlapping portion 53 where the double-sided adhesive tape 40 is wound longer than one turn around the outer peripheral surface 10 o of the barrel member 10 and the outer adhesive surface 51 and the inner adhesive surface 52 are adhered. It is formed on the double-sided adhesive tape 40. In the double-sided pressure-sensitive adhesive tape 40, at least the end 43 that was on the drawing direction D 22 side and the end 44 that was on the accommodation direction D 21 side are included in the overlapping portion 53. The base end portion 22 of the sheet-like member 20 is attached to at least the outside of the overlapping portion 53. The base end portion 22 shown in FIG. 9 is stuck to the outside of the sticking portion 511 including the overlapping portion 53. In this way, the base end portion 22 is fastened to the outer peripheral surface 10o of the barrel member 10.
　外側粘着面５１の内、基端部２２の裏側２１ｂに貼り付いている貼付部５１１は貼付部４１１であった部分であり、残りのはみ出し部５１２ははみ出し部４１２であった部分である。図９に示すはみ出し部５１２は、大部分が内側粘着面５２に貼り付いているが、一部が内側粘着面５２に貼り付いていない。また、内側粘着面５２の内、はみ出し部５１２とは反対側の第一部分５２１は第一部分４２１であった部分であり、第一部分５２１を除いて外周面１０ｏに直接貼り付けられた第二部分５２２は第二部分４２２であった部分であり、外側粘着面５１に貼り付いた第三部分５２３は第三部分４２３であった部分である。重なり部位５３は、内側粘着面５２の第三部分５２３に対応し、この第三部分５２３と外側粘着面５１のはみ出し部５１２とが貼り付いた部分である。 Of the outer adhesive surface 51, the affixing part 511 attached to the back side 21 b of the base end part 22 is the part that was the affixing part 411, and the remaining protruding part 512 is the part that was the protruding part 412. Most of the protruding portion 512 shown in FIG. 9 is attached to the inner adhesive surface 52, but a part thereof is not attached to the inner adhesive surface 52. The first portion 521 on the opposite side to the protruding portion 512 in the inner adhesive surface 52 is a portion that was the first portion 421, and the second portion 522 that is directly attached to the outer peripheral surface 10 o except for the first portion 521. Is the portion that was the second portion 422, and the third portion 523 that was attached to the outer adhesive surface 51 was the portion that was the third portion 423. The overlapping portion 53 corresponds to the third portion 523 of the inner adhesive surface 52 and is a portion where the third portion 523 and the protruding portion 512 of the outer adhesive surface 51 are attached.
　ここで、巻取軸２の周方向Ｄ１０において両面粘着テープ４０の外側粘着面５１が基端部２２に貼り付いた貼付部５１１の長さＬａが外周長Ｌｃよりも短いと（上記不等式（１））、両面粘着テープ４０が貼り付いた基端部２２が重ならずに両面粘着テープ４０の重なり部位５３が形成されている。この場合、両面粘着テープ４０の引き出し側の端４３が本体部分２１の接着端２２ａに引っ張られても内側の両面粘着テープ４０の外側粘着面５１に引き留められるので、バレル部材１０の外周面１０ｏに対する基端部２２の接着強度が向上している。
　また、外側粘着面５１に対する基端部２２の良好な粘着強度を得る点から、貼付部５１１の長さＬａは、外周長Ｌｃの１／２以上が好ましく、外周長Ｌｃの３／４以上がより好ましい。 Here, in the circumferential direction D10 of the winding shaft 2, when the length La of the affixing portion 511 where the outer adhesive surface 51 of the double-sided adhesive tape 40 is adhered to the base end portion 22 is shorter than the outer peripheral length Lc (the inequality (1 )), The overlapping portion 53 of the double-sided pressure-sensitive adhesive tape 40 is formed without overlapping the base end portion 22 to which the double-sided pressure-sensitive adhesive tape 40 is adhered. In this case, even if the pull-out side end 43 of the double-sided pressure-sensitive adhesive tape 40 is pulled by the adhesive end 22 a of the main body portion 21, the double-sided pressure-sensitive adhesive tape 40 is fastened to the outer pressure-sensitive adhesive surface 51 of the inner double-sided pressure-sensitive adhesive tape 40. The adhesive strength of the base end portion 22 is improved.
In addition, from the viewpoint of obtaining good adhesive strength of the base end portion 22 with respect to the outer adhesive surface 51, the length La of the sticking portion 511 is preferably 1/2 or more of the outer peripheral length Lc, and 3/4 or more of the outer peripheral length Lc. More preferred.
　さらに、巻取軸２の周方向Ｄ１０において両面粘着テープ４０の重なり部位５３の長さＬｂと貼付部５１１の長さＬａとの和Ｌａ＋Ｌｂは、外周長Ｌｃよりも長くされる。
　　Ｌｃ＜Ｌａ＋Ｌｂ　…（３）
　重なり部位５３の長さＬｂ自体は、外周面１０ｏに対する基端部２２の良好な接着強度を得る点から、外周長Ｌｃの１／１０以上が好ましく、外周長Ｌｃの１／６以上がより好ましい。また、両面粘着テープ４０を節約しながら外周面１０ｏに対する基端部２２の良好な接着強度を得る点から、重なり部位５３の長さＬｂは、外周長Ｌｃ以下が好ましく、外周長Ｌｃの１／２以下がより好ましい。尚、図８，９に示す巻取装置１において、重なり部位５３の長さＬｂは、はみ出し部４１２の長さＬｄよりも若干短い。 Further, the sum La + Lb of the length Lb of the overlapping portion 53 of the double-sided pressure-sensitive adhesive tape 40 and the length La of the sticking portion 511 in the circumferential direction D10 of the winding shaft 2 is made longer than the outer peripheral length Lc.
Lc <La + Lb (3)
The length Lb of the overlapping portion 53 is preferably 1/10 or more of the outer peripheral length Lc, and more preferably 1/6 or more of the outer peripheral length Lc, from the viewpoint of obtaining good adhesion strength of the base end portion 22 to the outer peripheral surface 10o. . In addition, the length Lb of the overlapping portion 53 is preferably equal to or less than the outer peripheral length Lc from the viewpoint of obtaining good adhesive strength of the base end portion 22 with respect to the outer peripheral surface 10o while saving the double-sided adhesive tape 40, and 1 / of the outer peripheral length Lc. 2 or less is more preferable. In the winding device 1 shown in FIGS. 8 and 9, the length Lb of the overlapping portion 53 is slightly shorter than the length Ld of the protruding portion 412.
　真夏の駐車等により車内が高温となると、両面粘着テープ４０の粘着剤が軟化してバレル部材１０の外周面１０ｏと両面粘着テープ４０との接着強度が低下することがある。図１１で示した比較例の巻取装置９０１では、引き出されたシート状部材２０の接着端２２ａに引っ張られて両面粘着テープ４０の引き出し側の端４３が外周面１０ｏから剥離する可能性がある。 When the inside of the vehicle becomes hot due to parking in midsummer or the like, the adhesive of the double-sided pressure-sensitive adhesive tape 40 may be softened and the adhesive strength between the outer peripheral surface 10o of the barrel member 10 and the double-sided pressure-sensitive adhesive tape 40 may be reduced. In the winding device 901 of the comparative example shown in FIG. 11, there is a possibility that the pull-out side end 43 of the double-sided pressure-sensitive adhesive tape 40 is peeled off from the outer peripheral surface 10 o by being pulled by the bonded end 22 a of the drawn sheet-like member 20. .
　本具体例では、図９に示すように、重なり部位５３において外側の両面粘着テープ４０の内側粘着面５２と内側の両面粘着テープ４０の外側粘着面５１とが強固に貼り付いている。このため、外側となる両面粘着テープ４０の引き出し側の端４３が本体部分２１の接着端２２ａに引っ張られても内側の両面粘着テープ４０に引き留められる。また、巻取軸２の外周面１０ｏに対する基端部２２の接着強度を向上させるために、巻取軸２等を複雑な形状にする必要が無く、巻取軸２等の重量増加等が抑制される。従って、本具体例は、巻取軸の外周面に対するシート状部材の基端部の接着強度を簡易な構造で向上させることができ、安価な対策により軽量な巻取装置を提供することができる。 In this specific example, as shown in FIG. 9, the inner adhesive surface 52 of the outer double-sided adhesive tape 40 and the outer adhesive surface 51 of the inner double-sided adhesive tape 40 are firmly attached at the overlapping portion 53. For this reason, even if the pull-out side end 43 of the double-sided pressure-sensitive adhesive tape 40 that is on the outside is pulled by the adhesive end 22 a of the main body portion 21, the double-sided pressure-sensitive adhesive tape 40 is fastened. Moreover, in order to improve the adhesive strength of the base end part 22 with respect to the outer peripheral surface 10o of the winding shaft 2, it is not necessary to make the winding shaft 2 etc. in a complicated shape, and an increase in the weight of the winding shaft 2 or the like is suppressed. Is done. Therefore, this specific example can improve the adhesive strength of the base end portion of the sheet-like member with respect to the outer peripheral surface of the winding shaft with a simple structure, and can provide a lightweight winding device by an inexpensive measure. .
