[Problem] To achieve, in a bearing seal for preventing electrolytic corrosion of a rolling bearing, reduction in conduction resistance and improvement in conduction stability, as well as easy manufacture. [Solution] A conductive fiber 5 is integrated with a surface layer part on one surface side of an elastic body 4, and a portion of the conductive fiber 5 is exposed from the surface. A portion of the conductive fiber 5 exposed from the surface, located at an outer circumferential part 8 of the elastic body 4 is brought into contact with an outer ring 11, and a portion of the conductive fiber 5 exposed from the surface, located at an inner circumferential part 9 of the elastic body 4 is brought into contact with an inner ring 12. Since the conductive fiber 5 is integrated with the surface layer part of the elastic body 4, the risk of detachment of the conductive fiber 5 from the elastic body 4 becomes significantly small. Since the conductive fiber 5 exposed from the surface of the elastic body 4 slidably comes into contact with the inner ring 12, conduction resistance is reduced and contact for conduction is stabilized. There is no manufacturing difficulty to integrate the conductive fiber 5 with the surface layer part of the elastic body 4 and to expose the portion of the conductive fiber 5 from the surface.

A circumferentially-facing inner surface 10 of the first annular member 1, positioned closer to a second annular member 2, has a shape such that a cross-sectional shape which is perpendicular to the axial direction J encloses a ball B in the radial direction. An axial direction distance E between an axial direction end part L1 of the circumferentially-facing inner surface 10, the axial direction end part L1 being far from the second annular member 2, and a revolution-orbital surface Q of the ball B is longer than an axial direction gap GJ1 between the first annular member 1 and the ball B.

Protective cover having sensor holder part, bearing device including the protective cover, and method for manufacturing the protective cover having the sensor holder part
A protective cover includes: a synthetic resin disc part having formed therein a separation wall which is thinner than other parts of the disc part and separates a magnetic encoder and a magnetic sensor from each other; and a synthetic resin sensor holder part protruding inward from the disc part. A gate mark caused by the injection molding is present n an outer peripheral surface of the disc part or an outer peripheral surface of a cylindrical part continuous with the disc part, in the radially outer side of the separation wall. Since the gate is at the radially outer side, of the separation wall, which is near the separation wall, no charging end weld is generated on the separation wall when a molten synthetic resin material is injected from the gate into the cavity of the injection mold die and solidified in an injection molding step.

The present invention is intended to provide an injection molding die that improves the strength of adhesion between an insert and a plastic in an insert molded article while suppressing fluctuations in the strength of adhesion.
An injection molding die is used to manufacture an insert molded article by placing an insert 12 with a thermoset resin adhesive in the molding die and injecting a molten plastic material P from a gate G into a cavity C. The gate G is arranged at a position separated by 0.2 mm or more in an out-of-plane direction from a surface A1 of the adhesive applied to the joining surface of the insert 12. During injection molding, the wall surface shear stress generated on the adhesive applied to the joining surface of the insert 12 relative to the plastic near the gate G becomes small. The adhesive is not swept away by the high-pressure molten plastic material P without having to bring the adhesive applied to the joining surface A of the insert 12 into the semi-cured state. Accordingly, it is possible to conduct injection molding without bringing the adhesive into the semi-cured state.
