To provide a wiper arm by which the wiper arm can be easily and securely mounted on a pivot shaft (an output shaft).SOLUTION: An arm member 22 is provided with an opening 22x, which enables a fastening portions (a fixed hole 21a, an external thread part 11b and nut 15) of an arm head 21 and a pivot shaft 11 to face outside. When the opening 22x is uncovered by a cover member 27, a restricting piece 27c of the cover member 27 is interposed between the arm head 21 and the arm member 22, so that displacement of an urged coil spring 23 on the leading-end side of the arm member 22 toward a to-be-wiped surface can be hindered. When the opening 22x is uncovered by the cover member 27, the restricting piece 27c of the cover member 27 is released from being interposed between the arm head 21 and the arm member 22, so that displacement of an urged coil spring 23 on the leading-end side of the arm member 22 toward the to-be-wiped surface can be cancelled.SELECTED DRAWING: Figure 4
【課題】ピボット軸(出力軸)に対するワイパアームの取付作業を容易且つ確実に行うことができるワイパアームを提供する。【解決手段】アーム部材22に対し、アームヘッド21とピボット軸11との締結部分(固定孔21a、雄ネジ部11b及びナット15)を外部に臨ませることを可能とする開口部22xが設けられ、カバー部材27にてその開口部22xを開放状態とした場合、カバー部材27の規制片部27cがアームヘッド21とアーム部材22との間に介在して、アーム部材22の先端側の付勢コイルバネ23による払拭面側への変位の規制が図れる。カバー部材27により開口部22xを閉塞状態とした場合、カバー部材27の規制片部27cがアームヘッド21とアーム部材22との間にて非介在となり、アーム部材22の先端側の付勢コイルバネ23による払拭面側への変位の規制の解除が図れる。【選択図】図4
