摘要： Provided is a grease composition containing a base oil, a thickener, and an additive. The base oil contains a poly-α-olefin and has a kinematic viscosity of 20-60 mm2/s at 40° C. The thickener contains a urea compound produced by reacting a diisocyanate compound with a mixed amine containing an alicyclic amine and an aromatic amine. The additive contains a phosphorous acid ester, an ether compound, and an oxidized paraffin.

摘要： A ball joint includes a tubular boot, an upper end portion and a lower end portion of which are fitted onto an intermediate portion of a shaft of a ball stud and an open end of a housing, respectively. An annular lip portion is formed at the upper end portion of the boot. The lip portion has a first sliding contact face that is in contact with an outer periphery of the shaft, a second sliding contact face that is in contact with a lower face of the knuckle arm, and an annular rib that is formed so as to project inward beyond the first sliding contact face from an upper end portion of the first sliding contact face. The rib is elastically deformed due to contact with the shaft so as to extend along the first sliding contact face and project upward beyond the second sliding contact face.

摘要： Through-holes are formed in an axially intermediate portion of a cylindrical portion of a first metal core, at predetermined intervals in a circumferential direction, and the through-holes pass through the cylindrical portion in a radial direction. A first elastic seal has a lip that is in sliding contact with an outer peripheral face of a cylindrical portion of a second metal core, a first cylindrical portion that is in close contact with an inner peripheral face of an axially inner-side portion of the cylindrical portion of the first metal core, a second cylindrical portion that is in close contact with an outer peripheral face of an axially outer-side portion of the cylindrical portion of the first metal core, and connecting pieces that are inserted into the through-holes of the cylindrical portion of the first metal core and that connect the first cylindrical portion with the second cylindrical portion.

摘要： An annular groove, in which a lower end of a boot is fitted, is formed in an outer periphery of an open end of a housing so as to extend in a circumferential direction of the housing. The annular groove is defined by a cylindrical face, an upper inner wall, and a lower inner wall. By fitting a clip onto a cylindrical portion of the lower end of the boot, the cylindrical portion is pushed against the cylindrical face, and an inner end portion and a folded-back portion are pushed against the upper inner wall and the lower inner wall, respectively. The inner end portion has an annular protrusion that is engaged with the upper inner wall and elastically contracted when the lower end of the boot is fitted in the annular groove.
