Abstract
A shaft sealing device comprising: a first member; a second member provided with a through-hole through which the first member passes; a sealing member configured to seal a gap between the through-hole and the first member; a rotation restricting part restricting relative rotation between the first and second members; and an axial displacement restricting part restricting the axial displacement of the sealing member. The rotation restricting part includes a first contact portion provided on the first member, a second contact portion provided on the sealing member and an inclined surface included on the first contact portion. The axial displacement restricting part includes a stopper surface. When the sealing member rotates in one direction relative to the second member by being dragged by the first member, the sealing member contacts the stopper surface to restrict the axial displacement of the sealing member.
