摘要： A sealing device includes an annular reinforcing ring fixed to a housing, an annular elastic member that includes a fixing portion fixed to the reinforcing ring, and a lip that protrudes from the fixed portion and is in slidable contact with an outer peripheral surface of a shaft, and at least one annular spring that presses the lip against the outer peripheral surface of the shaft, the lip being between the at least one spring and the outer peripheral surface of the shaft. The elastic member is made of an electrically conductive elastic material. A contact surface, which is a part of the lip and is in contact with the outer peripheral surface of the shaft, is straight when viewed in a cross section defined by a plane that includes a central axis of the elastic member. A width of the at least one annular spring is greater than its thickness.

摘要： To provide a method for manufacturing a sealing device having high pressure-resistance and high durability.
Provided is a method for manufacturing a sealing device to be provided between a shaft and an inner surface of a shaft hole in which the shaft is provided, the method comprising: a step for forming an atmosphere-side rigid ring by forming a through-hole in a rigid body by a punching-out process; a step for causing a reinforcement ring for reinforcing an elastic ring to contact the elastic ring in a direction parallel to the axial direction of the shaft, wherein the elastic ring is made of an elastic body, is attached to a liquid-side rigid ring made of a rigid body and disposed inside the shaft hole, is disposed radially inward of the liquid-side rigid ring, and has formed thereon a seal lip that slidably makes sealing contact with the shaft; and a step for causing the atmosphere-side rigid ring to contact the reinforcement ring in a direction parallel to the axial direction of the shaft so that a surface contacted by an end surface of a punch during the punching-out process of the atmosphere-side rigid ring is positioned on an opposite side to the reinforcement ring.
