摘要:
The object of the present disclosure is to accomplish a stable sealing performance while maintaining the durability. A mating ring (120) includes a sliding portion (121) having a sliding surface that slides against a sealing ring (110) within an end surface on an atmosphere side (A) thereof in an axial direction of a shaft (200), and a retained portion (122) that extends from a radially outward end portion of the sliding portion (121) toward a sealed-fluid side (F) in the axial direction and is retained by a sleeve (130). A mechanical seal (100) includes an annular holder (500) that is fixed to the sleeve (130) receives pressure from an O-ring (140) that receives, from the sealed-fluid side (F) in the axial direction, a fluid pressure (P) of a fluid to be sealed that flew into a space created by a flange portion (132) of the sleeve (130) and the retained portion (122) of the mating ring (120).
