Abstract:
A dust cover that allows a dust lip part thereof to offer sealing performance stably for a long period of time. A sealing part  130  includes an inner peripheral sealing part that can slide relative to an outer peripheral surface of a shaft part, and a dust lip part  132  that can slide relative to an end surface of a knuckle  400 , wherein an annular protrusion  135  that protrudes radially outward is formed at an end of the sealing part  130  on the other end side, and at least one of inner and outer peripheral surfaces of the dust lip part  132  extends toward the other end side from recessed parts  132 a  and  132 b  of the sealing part  130  being recessed toward one end side with respect to an end surface  135 a  of the annular protrusion  135  on the other end side.

Claim (Index 1):
A dust cover for use in a ball joint including a ball stud having a spherical part at one end of a shaft part thereof, a socket that has a bearing for the spherical part and supports the ball stud in a rotatable and swingable manner, and a coupling member that couples with the shaft part on a side of the shaft part opposite to the spherical part,\n the dust cover comprising: a deformable body part; a fixed part provided on one end side of the body part and fixed to the socket; and a sealing part provided on the other end side of the body part and provided slidably relative to the shaft part and the coupling member, the sealing part including: an inner peripheral sealing part that can slide relative to an outer peripheral surface of the shaft part; and a dust lip part that is configured to be inclined radially outwardly and toward the other end side, and that can slide relative to an end surface of the coupling member, wherein an annular protrusion that protrudes radially outward is formed at an end of the sealing part on the other end side, and an outer peripheral surface of the dust lip part extends toward the other end side from a recessed part of the sealing part being recessed toward the one end side with respect to an end surface of the annular protrusion on the other end side.
