This shock absorber generates a damping force by imparting resistance to a working fluid. The shock absorber includes a cylinder filled with the working fluid, a piston sliding against an inner peripheral surface of the cylinder, a piston rod coupled to the piston and projecting outward from the cylinder, and an elastic resin seal ring slidingly supporting an outer peripheral surface of the piston rod. At least one of the outer peripheral surface of the piston rod, the inner peripheral surface of the cylinder, and the outer peripheral surface of the piston has a multi-element amorphous film with a hydrogen content of 15 at% or more. Cet amortisseur génère une force d'amortissement en conférant une résistance à un fluide de travail. L'amortisseur comprend un cylindre rempli du fluide de travail, un piston coulissant contre une surface périphérique intérieure du cylindre, une tige de piston couplée au piston et faisant saillie vers l'extérieur à partir du cylindre, ainsi qu'une bague d'étanchéité en résine élastique supportant de manière coulissante une surface périphérique extérieure de la tige de piston. Au moins l'une de la surface périphérique extérieure de la tige de piston, de la surface périphérique intérieure du cylindre et de la surface périphérique extérieure du piston comporte un film amorphe à éléments multiples ayant une teneur en hydrogène de 15% atomique ou plus. この緩衝器は、作動流体に抵抗を付与することによって減衰力を生じる緩衝器であって、前記作動流体が充填されるシリンダと、前記シリンダの内周面に対し摺動するピストンと、前記ピストンに結合され、前記シリンダから外部に突出するピストンロッドと、前記ピストンロッドの外周面を摺動自在に支持する弾性樹脂シールリングを備え、前記ピストンロッドの外周面、前記シリンダの内周面、前記ピストンの外周面の少なくとも１つに、Ｈ含有量が１５ａｔ％以上である多元アモルファス膜を有する。
