Description

なお、ワッシャ３０のシール形成部３２における径方向外側に向くシール形成部外径面３２ｂと、それに対向するプーリアームのアーム内径面３ｃとの間の隙間Ｃは、プーリアーム３と円筒支持材１４との間のすべり軸受のラジアル隙間よりも大きくなるように設定されている。ここで、プーリアーム３と円筒支持材１４との間のすべり軸受のラジアル隙間とは、プーリアーム３のアーム内径面の半径と円筒支持材１４の外径面１４ｂの半径との差から、軸受ブッシュ１２の組み込み後の径方向厚さを差し引いた寸法である。
ワッシャ３０とプーリアーム３との径方向の隙間Ｃを、すべり軸受のラジアル隙間よりも大きくすることで、回転側であるプーリアーム３と固定側であるワッシャ３０との接触を避けることができる。 A gap C between the seal forming portion outer diameter surface 32 b facing outward in the radial direction of the seal forming portion 32 of the washer 30 and the arm inner diameter surface 3 c of the pulley arm facing the seal forming portion 32 is formed between the pulley arm 3 and the cylindrical support member 14. It is set to be larger than the radial clearance of the sliding bearing between. Here, the radial clearance of the sliding bearing between the pulley arm 3 and the cylindrical support member 14 is the difference between the radius of the arm inner surface of the pulley arm 3 and the radius of the outer surface 14b of the cylindrical support member 14, and the bearing bush 12. It is a dimension obtained by subtracting the radial thickness after installation.
By making the radial gap C between the washer 30 and the pulley arm 3 larger than the radial gap of the plain bearing, contact between the pulley arm 3 on the rotating side and the washer 30 on the fixed side can be avoided.
