Summary:PROBLEM TO BE SOLVED: To suppress a play of a wiper blade to a wiper arm.SOLUTION: In a vehicular wiper 10, even when a second small-diameter part 78B of a second support shaft 78 is disposed on a second opening part 66 side, a first small-diameter part 76B of a first support shaft 76 can be disposed on a side opposite to a first opening part 56 because the first small-diameter part 76B and the second small-diameter part 78B are disposed in point-symmetry positions with respect to an axis CL1. In this case, because a first arc part 76A closes the first opening part 56, movement of a support shaft 74 to the first opening part 56 side (the base end side of a retainer 18) in at least the first support shaft 76 is suppressed. Thereby, a play of a wiper blade 20 to a wiper arm 12 (the retainer 18) can be suppressed. 【課題】ワイパアームに対するワイパブレードのがたを抑制する。【解決手段】車両用ワイパ10では、第1支軸76の第1小径部76Bと第2支軸78の第2小径部78Bとが、軸線CL1に対して点対称の位置に配置されているため、第2小径部78Bが第2開口部66側に配置された場合でも、第1小径部76Bを第1開口部56とは反対側に配置できる。そして、この場合には、第1円弧部76Aによって第1開口部56を塞ぐようになるため、支軸74では、少なくとも第1支軸76における第1開口部56側(リテーナ18の基端側)への移動が抑制される。これにより、ワイパアーム12(リテーナ18)に対するワイパブレード20のがたを抑制できる。【選択図】図3
