The coil portion is configured in such a manner as to induce a magnetic field. The iron core portion is arranged in such a manner as to extend from a first region to a second region of the metal member so as to straddle over the rubber member, and passes through the coil portion.

A gear device includes a resin gear that is formed of a first resin material, and a connected member that is formed of a second resin material and that is connected to the resin gear, in which the first resin material is a fiber-reinforced resin obtained by filling a first base material resin with first reinforcement fibers, the second resin material is a fiber-reinforced resin obtained by filling a second base material resin with second reinforcement fibers, and a fiber content ratio of the second reinforcement fibers in the second resin material is higher than a fiber content ratio of the first reinforcement fibers in the first resin material.

A cage is provided which is less likely to be deformed by a centrifugal force, and in which the strength of a weld is less likely to decrease. Each horn portion includes a base wall axially connected to a ring portion, and located between pockets; and a pair of claws separated from each other. The pair of claws each has a pocket inner surface facing the pocket; and an opposed surface (14) on the side opposite from the pocket inner surface. The base wall includes a pair of connection portions axially connecting the respective claws to the ring portion; and an intermediate portion circumferentially connecting the connection portions to each other. A weld is disposed in a resin area consisting of one of the claws, one of the connection portions, and a circumferential section of the ring portion.

A glass-fiber-reinforced thermoplastic resin molding product is provided, which has a ring-shaped structure, and includes a thermoplastic resin, and a fibrous filler dispersed in the thermoplastic resin. The fibrous filler includes: (A) 40 to 80% of glass fibers each having a length of at least 0.05 mm and less than 0.5 mm; (B) 15 to 40% of glass fibers each having a length of at least 0.5 mm and less than 1.0 mm; (C) 5 to 30% of glass fibers each having a length of at least 1.0 mm and less than 3.0 mm; and (D) at most 1% of glass fibers each having a length of at least 3.0 mm,
based on the total number of fibers of the fibrous filler present in the molding product.

The resin injection gate is disposed at the pillar part. When the bearing cage is divided into first and second regions by an imaginary line connecting the resin injection gate and a weld to be formed at a position radially facing the resin injection gate, a resin reservoir that can store therein the melted resin is formed at the pillar part in only one of the regions. A circumferential distance between the resin reservoir and the weld is smaller than a circumferential distance between the resin reservoir and the resin injection gate. A cross-sectional area of a communicating part of the resin reservoir, which is configured to communicate with the pillar part, is equal to or less than a quarter of a cross-sectional area of the resin injection gate.

To provide a fluorinated copolymer composition having improved impact resistance and excellent moldability without impairing the excellent heat resistance and mechanical properties inherent to a thermoplastic heat-resistant resin. This fluorinated copolymer composition comprises a thermoplastic resin A being a melt-moldable heat-resistant thermoplastic resin and a fluorinated elastomer B being a fluorinated elastic copolymer, wherein the fluorinated elastomer B is dispersed in the thermoplastic resin A, the number average particle diameter of the fluorinated elastomer B is from 1 to 300 m, the volume ratio of the thermoplastic resin A to the fluorinated elastomer B is from 97:3 to 55:45, and the fluorinated copolymer composition has a flexural modulus of from 1,000 to 3,700 MPa.

A method includes a coating step of coating a vulcanizing adhesive at a surface of a vulcanized centrum of a rubber bush; a heating step of heating a portion to be adhered of a stabilizer bar; a fitting step of fitting the centrum of the rubber bush at which the vulcanizing adhesive is coated on the heated portion to be adhered of the stabilizer bar; and an adhering step of clamping the rubber bush in a radial direction by a clamping device to adhere the rubber bush on the portion to be adhered of the stabilizer bar.

A bearing holder is to be formed by injecting a melted resin, from a plurality of resin injection gates provided at a peripheral edge portion of a substantially annular cavity formed in a molding die, into the cavity. At least one column portion is provided with a resin reservoir capable of reserving therein the melted resin. A cross-sectional area of a communication portion of the resin reservoir configured to communicate with the column portion is equal to or smaller than of a cross-sectional area of the resin injection gate.

A bearing element for receiving a stabilizer on a vehicle may include a first elastomer body and a second elastomer body that are of half-shell-shaped design and that are arranged on one another so as to form a receiving passage. The receiving passage may receive a stabilizer rod of the stabilizer. The first and second elastomer bodies can be pressed onto and cohesively attached to the stabilizer rod of the stabilizer such that the stabilizer rod extends through the receiving passage. Further, the inner contour of the receiving passage may be configured so as to deviate from a circular contour.

The operating device, in particular for a vehicle component, is provided with a rotary operating element (18), which can be rotated about a rotation axis (20) and is formed as a plastic injection-molded part, which is produced in a molding die (48) having a die separation plane (46), and with a bearing unit (12), on which the rotary operating element (18) is mounted such that it can rotate about the rotation axis (20). The bearing unit (12) has a first bearing element (14), which is formed as a plastic injection-molded part, which is produced in a molding die (28) having a die separation plane (34). The first bearing element (14) has a bearing surface (26), which extends in a radial plane to the rotation axis (20) and concentrically to same, and the rotary operating element (18) has a contact surface (36), which bears against the bearing surface (26) and likewise extends in a radial plane to the rotation axis (20) and concentrically to same. Either the bearing surface (26) of the first bearing element (14) or the contact surface (36) of the rotary operating element (18) is arranged outside the die separation plane (34; 46) of the injection-molding die (28; 48) for said relevant element (14; 18), and the other of the two surfaces (26; 36) is arranged in the die separation plane (34; 46) of the injection-molding die (28; 48) of said relevant element (14; 18).
