Description

シール部材２０は、弾性材製で、全体として円環形状に構成されている。シール部材２０は、シール保持溝３３への装着前に、円環形状をある程度保持できるように、アクリロニトリルブタジエンゴム（ＮＢＲ、高硬度ニトリル）などの、硬度がＨｓ８５以上Ｈｓ９５以下（Ｈｓ９０±５）の材料製としている。本例では、シール部材２０の硬度を、Ｈｓ９０程度としている。 The seal member 20 is made of an elastic material and has an annular shape as a whole. The seal member 20 is made of acrylonitrile butadiene rubber (NBR, high hardness nitrile) or the like, and has a hardness of Hs 85 or more and Hs 95 or less ( Hs 90±5) so that it can maintain its annular shape to some extent before being attached to the seal holding groove 33. It is made of materials. In this example, the hardness of the seal member 20 is approximately Hs90.
