Claims

[Scope of utility model registration request]

A shaft sealing device for when a rotating shaft is pivotally supported by a housing includes a fixed ring whose outer peripheral end is fixed to the housing and through which the rotating shaft is inserted through an inner space; a rotation transmission member that rotates integrally; a driven ring made of a soft material that is disposed on the rotation shaft via a seal member and rotates in response to the rotation of the rotation transmission member while slidingly contacting a side surface of the fixed ring; a metal retainer disposed on a side surface of the driven ring and having the same outer circumference as the driven ring; and a metal retainer disposed between the retainer and the rotation transmission member and connecting the driven ring to the fixed ring via the retainer. when viewed in a cross section perpendicular to the axis of the rotating shaft, recesses of the same shape are formed at the same position on the outer peripheries of the driven ring and the retainer, respectively, and the rotation transmission A shaft sealing device, wherein the member is formed with a convex portion that fits into the concave portion when viewed in a cross section perpendicular to the axis of the rotating shaft.
