To decrease a degree of bending or expanding/contracting of a wiring member with rotations of a wiper arm body, when the wiring member is wired from the wiper arm body side to a vehicle side.SOLUTION: A wiper arm is equipped with a wiper arm body coupled with a wiper blade at a tip end portion, and a bearing that has a bush 56 attached to a base end portion of the wiper arm body and a shaft member 58 rotatably fitted with the inside of the bush 56. The wiper arm body is rotated about the bearing with respect to a vehicle. The shaft member 58 is supported by the vehicle while an inner space 68 is opened to both side in an axial direction, so that a wiring member (wiring) can be wired from the vehicle side to the wiper arm body side through the space 68. In that case, the wiring member passes through a center portion of the bearing, so that a degree of bending or expanding/contracting of the wiring member with rotations of the wiper arm body can be decreased as compared with a conventional one.SELECTED DRAWING: Figure 5
【課題】ワイパアーム本体側から車両側に配索部材が配索される場合に、ワイパアーム本体の回動に伴って配索部材が屈曲や伸縮等をする度合いを従来よりも小さくする。【解決手段】ワイパアームは、ワイパブレードが先端部に連結されるワイパアーム本体と、ワイパアーム本体の基端部に取り付けられるブッシュ56及びブッシュ56の内側に回転自在に嵌合する軸部材58を有する軸受とを備えており、この軸受け回りにワイパアーム本体が車両に対して回動される。上記の軸部材58は、内側の空間68が軸線方向両側に開放された状態で車両に支持されるので、当該空間68を通して車両側からワイパアーム本体側に配索部材(例えば配線)を配索することができる。その場合、配索部材が軸受の中心部を通るので、ワイパアーム本体の回動に伴って配索部材が屈曲や伸縮等をする度合いを、従来よりも小さくすることができる。【選択図】図5
