Description

本実施形態の嵌合部６０，６１は、第１実施形態の嵌合部４２ｂ，４３ｂと以下の点で相違する。即ち、上側のヨーク４２の嵌合部６０は、嵌合部４２ｂに比し軸方向に長く形成され、２個のシール部材３３，３３の収容が可能とされている。嵌合部６０は、図４に示すように軸方向に上下に並べたシール部材３３，３３と嵌合する寸法形状に形成され、上側のシール部材３３は、軸受３１と接するようになっている。シール部材３３，３３の対向間であって、それらリップ４６，４６間の部分に隙間Ｇ２が形成されており、当該隙間Ｇ２はグリース溜め部とされている。具体的には、隙間Ｇ２には、例えば、ＪＩＳ分類０号〜３号までの稠度を有する半固体状のウレア系グリースが充填されている。このグリースによって、シール部材３３，３３とシャフト２４との間の潤滑作用を向上させ、シール部材３３，３３の摩耗を抑制することができる。 The fitting parts 60 and 61 of this embodiment differ from the fitting parts 42b and 43b of 1st Embodiment by the following points. That is, the fitting portion 60 of the upper yoke 42 is formed longer in the axial direction than the fitting portion 42b, and can accommodate the two seal members 33, 33. As shown in FIG. 4, the fitting portion 60 is formed in a size and shape that fits with the seal members 33, 33 arranged vertically in the axial direction, and the upper seal member 33 is in contact with the bearing 31. . A gap G2 is formed between the lips 46 and 46 between the seal members 33 and 33, and the gap G2 is a grease reservoir. Specifically, the gap G2, for example, semi-solid urea-based grease having a consistency of up to J IS classification No. 0 to 3 No. is filled. With this grease, the lubricating action between the seal members 33 and 33 and the shaft 24 can be improved, and wear of the seal members 33 and 33 can be suppressed.
