- the bottom surface 45 of the groove 44 is an inclined surface, the depth of the groove 44 becomes shallower toward the vertical upper side. From this point of view, even if there is a space for movement above the wiring member 50 on the most vertically upper side, the range of movement is limited. As a result, the wiring member 50 and the inner surface of the groove 44 are less likely to collide with each other during vibration, and even if they collide, a loud noise is less likely to occur.

Abstract
Description
最初に本開示の実施態様を列記して説明する。
本開示の配線モジュールの具体例を、以下に図面を参照しつつ説明する。なお、本開示はこれらの例示に限定されるものではなく、請求の範囲によって示され、請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。
以下、実施形態1にかかる配線モジュールについて説明する。図1は実施形態1にかかる配線モジュール30及びこれが組み込まれるドアパネル20を示す平面図である。図2は図1のII-II線に沿った断面図である。図3はカバー部材60がベース部材40に固定される様子を示す模式図である。
溝44の内部において、配線部材50が第1側縁部46の側に寄っており、カバー本体62には、第2側縁部48の側に溝44の内部に入り込む突出部63が設けられていることによって、溝44の内部空間が狭められる。これにより、溝44の内部において配線部材50が移動できるスペースが小さくなり、配線部材50と溝44の内面とが衝突しにくくなる。また、衝突したとしても、配線部材50が移動できるスペースが小さい分、衝突時の配線部材50のエネルギーが小さくなる。これらより、配線部材50が溝44に保持された配線モジュール30において、大きな音の発生を抑制することができる。
これまで、配線モジュール30がドア10に組み込まれるものとして説明されたが、このことは必須の構成ではない。配線モジュール30は、車両において、ドア10以外の部位に組込まれてもよい。この場合、ベース部材40は、組み込まれる位置に応じた部材が用いられるとよい。例えば、配線モジュールはインストルメントパネルに組込まれてもよい。この場合、ベース部材はインストルメントパネルであってもよい。
