［本開示の実施形態の説明］
　最初に本開示の実施態様を列挙して説明する。 [Explanation of Embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
（１）本開示は、電線が収容される外装体であって、前記電線の延び方向に延びるベースシートと、前記ベースシートと折れ曲がり部を介して連なるとともに、前記電線の前記延び方向と交差する交差方向に延びる複数のスリットにより分割された複数のカバー片と、を有し、前記複数のカバー片は前記折れ曲がり部において前記ベースシートに重なるように折り返されており、前記ベースシートと前記複数のカバー片のそれぞれは、前記折れ曲がり部と反対側の端部に形成された接合部において接合されており、前記電線は、前記ベースシートと前記複数のカバー片との間に挟まれている。 (1) The present disclosure is an exterior body in which an electric wire is housed, and the base sheet extending in the extending direction of the electric wire is connected to the base sheet via a bent portion and intersects the extending direction of the electric wire. It has a plurality of cover pieces divided by a plurality of slits extending in the intersecting direction, and the plurality of cover pieces are folded back so as to overlap the base sheet at the bent portion, and the base sheet and the plurality of cover pieces are folded. Each of the cover pieces is joined at a joint formed at an end opposite to the bent portion, and the electric wire is sandwiched between the base sheet and the plurality of cover pieces.
　電線は、ベースシートと、複数のカバー片との間に挟まれているので、電線と外装体との間にデッドスペースが生じにくくなっている。これにより、外装体を、ベースシートと複数のカバー片とが重ねられた方向について薄型化できる。 Since the electric wire is sandwiched between the base sheet and a plurality of cover pieces, dead space is less likely to occur between the electric wire and the exterior body. As a result, the exterior body can be made thinner in the direction in which the base sheet and the plurality of cover pieces are overlapped.
（２）前記折れ曲がり部は、前記ベースシート側に設けられた第１折れ曲がり部と、前記第１折れ曲がり部との間に間隔を空けて、前記複数のカバー片側に設けられた第２折り曲がり部と、を有することが好ましい。 (2) The bent portion is provided on one side of the plurality of covers with a space between the first bent portion provided on the base sheet side and the first bent portion. And, it is preferable to have.
　第１折り曲がり部と第２折れ曲がり部との間隔を調節することにより、ベースシートと複数のカバー片との間隔を容易に調節できる。これにより、異なる直径を有する電線に容易に対応できる。 By adjusting the distance between the first bent part and the second bent part, the distance between the base sheet and the plurality of cover pieces can be easily adjusted. This makes it easy to handle wires with different diameters.

［本実施形態の作用効果］
　続いて、本実施系形態の作用効果について説明する。本実施形態にかかる外装体７０は、電線１２が収容される外装体７０であって、電線１２の延び方向に延びるベースシート７３と、ベースシート７３と折れ曲がり部７２を介して連なるとともに、電線１２の延び方向と交差する交差方向に延びる複数のスリット７４により分割された複数のカバー片７５と、を有し、複数のカバー片７５は折れ曲がり部７２においてベースシート７３に重なるように折り返されており、ベースシート７３と複数のカバー片７５のそれぞれは、折れ曲がり部７２と反対側の端部に形成された接合部７７において接合されており、電線１２は、ベースシート７３と複数のカバー片７５との間に挟まれている。 [Action and effect of this embodiment]
Subsequently, the action and effect of the present embodiment will be described. The exterior body 70 according to the present embodiment is an exterior body 70 in which the electric wires 12 are housed, and is connected to the base sheet 73 extending in the extending direction of the electric wires 12 via the base sheet 73 and the bent portion 72, and the electric wires 12 It has a plurality of cover pieces 75 divided by a plurality of slits 74 extending in an intersecting direction intersecting the extending direction of the cover piece 75, and the plurality of cover pieces 75 are folded back at a bent portion 72 so as to overlap the base sheet 73. , Each of the base sheet 73 and the plurality of cover pieces 75 is joined at a joint portion 77 formed at an end opposite to the bent portion 72, and the electric wire 12 is joined to the base sheet 73 and the plurality of cover pieces 75. It is sandwiched between.
　また、本実施形態にかかるワイヤーハーネス１１は、上記の外装体７０と、外装体７０に収容される電線１２と、を備える。 Further, the wire harness 11 according to the present embodiment includes the above-mentioned exterior body 70 and the electric wire 12 housed in the exterior body 70.
　電線１２は、ベースシート７３と、複数のカバー片７５との間に挟まれているので、電線１２と外装体７０との間にデッドスペースが生じにくくなっている。これにより、外装体７０を、ベースシート７３と複数のカバー片７５とが重ねられた方向について薄型化できる。 Since the electric wire 12 is sandwiched between the base sheet 73 and the plurality of cover pieces 75, a dead space is less likely to occur between the electric wire 12 and the exterior body 70. As a result, the exterior body 70 can be made thinner in the direction in which the base sheet 73 and the plurality of cover pieces 75 are overlapped.
　また、本実施形態によれば、複数のスリット７４のうちベースシート７３側の端部には円形孔７６が形成されている。これにより、スリット７４に外力が加えられた場合に、円形孔７６において力が分散されるので、スリット７４の端部を起点にしてベースシート７３または複数のカバー片７５が裂けることを抑制できる。 Further, according to the present embodiment, a circular hole 76 is formed at the end of the plurality of slits 74 on the base sheet 73 side. As a result, when an external force is applied to the slit 74, the force is dispersed in the circular hole 76, so that it is possible to prevent the base sheet 73 or the plurality of cover pieces 75 from being torn starting from the end portion of the slit 74.
　また、本実施形態によれば、接合部７７において、ベースシート７３と複数のカバー片７５のそれぞれとは、熱融着されている。 Further, according to the present embodiment, in the joint portion 77, the base sheet 73 and each of the plurality of cover pieces 75 are heat-sealed.
　ベースシート７３と複数のカバー片７５とを熱融着するという簡易な手法により接合できるので、外装体７０の製造コストを低減できる。 Since the base sheet 73 and the plurality of cover pieces 75 can be joined by a simple method of heat fusion, the manufacturing cost of the exterior body 70 can be reduced.

　上記以外の構成については、実施形態１と略同様なので、同一部材については同一符号を付し、重複する説明を省略する。 Since the configurations other than the above are substantially the same as those in the first embodiment, the same members are designated by the same reference numerals, and duplicate description will be omitted.
　本実施形態によれば、折れ曲がり部８２は、ベースシート８３側に設けられた第１折れ曲がり部８２Ａと、第１折れ曲がり部８２Ａとの間に間隔を空けて、複数のカバー片８５側に設けられた第２折れ曲がり部８２Ｂと、を有する。 According to the present embodiment, the bent portion 82 is provided on the plurality of cover pieces 85 side with a space between the first bent portion 82A provided on the base sheet 83 side and the first bent portion 82A. It also has a second bent portion 82B.
　第１折れ曲がり部８２Ａと第２折れ曲がり部８２Ｂとの間隔を調節することにより、ベースシート８３と複数のカバー片８５との間隔を容易に調節できる。これにより、異なる直径を有する電線１２に容易に対応できる。 By adjusting the distance between the first bent portion 82A and the second bent portion 82B, the distance between the base sheet 83 and the plurality of cover pieces 85 can be easily adjusted. This makes it possible to easily handle electric wires 12 having different diameters.
＜他の実施形態＞
（１）ベースシート７３とカバー片７５とは超音波融着される構成としたが、ヒータによって加圧しつつ加熱することにより融着される構成としてもよい。 <Other Embodiments>
(1) Although the base sheet 73 and the cover piece 75 are ultrasonically fused, they may be fused by heating while pressurizing with a heater.
（２）実施形態１では１つの折れ曲がり部７２が形成され、実施形態２では第１折れ曲がり部８２Ａと第２折れ曲がり部８２Ｂが形成される構成としたが、３つ以上の折れ曲がり部が形成される構成としてもよい。 (2) In the first embodiment, one bent portion 72 is formed, and in the second embodiment, the first bent portion 82A and the second bent portion 82B are formed, but three or more bent portions are formed. It may be configured.
（３）円形孔は省略してもよい。 (3) The circular hole may be omitted.
