PROBLEM TO BE SOLVED: To avoid that a serration unprocessed part is formed at a pressure-insertion shaft part, in a member having the pressure-insertion shaft part which is applied with serration processing such as a ball pin of a wiper device and a shaft part of a pivot shaft.SOLUTION: In a pivot member for a wiper device, a ball part 30a of a ball pin 30 or a support part 22a of a pivot shaft 22 being a pivot part is formed at one end side, flange parts 30d, 22d are formed at the other end side, pressure-insertion shaft parts 30b, 22b which are applied with serration processing are formed at the flange parts 30d, 22d, and the pressure-insertion shaft parts 30b, 22b are pressure-fixed into holes 24a, 24b which are formed at an oscillating or turning member 24. Grooves 30f, 22f having prescribed depths are formed at the flange parts 30d, 22d along root-side external peripheries of the pressure-insertion parts 30b, 22b, and in the pressure-insertion shaft parts 30b, 22b, serration processing parts 30e, 22e are arranged up to positions corresponding to at least the grooves 30f, 22f.SELECTED DRAWING: Figure 6
【課題】ワイパ装置におけるボールピンやピボット軸のシャフト部等のセレーション加工された圧入軸部を備える部材において、圧入軸部にセレーション未加工部が形成されないようにすること。【解決手段】一端側に枢支部となるボールピン30のボール部30aないしピボット軸22の支持部22aが、他端側につば部30d,22dがそれぞれ形成され、つば部30d,22dにはセレーション加工された圧入軸部30b,22bが形成され、圧入軸部30b,22bが揺動又は回動する部材24に形成された穴内24a、24bに圧入固定されたワイパ装置用枢支部材であって、つば部30d,22dには圧入軸部30b,22bの根元側外周に沿って所定深さの溝30f,22fが形成されており、圧入軸部は30b,22b少なくとも溝30f,22fに対応する位置までセレーション加工部30e,22eが設けられている。【選択図】図6
