Abstract: In a frictional hinge device, a diameter-increased section 11 of a rotation shaft 10 is formed so that the surface roughness (Ra) is 0.05˜0.20 &mgr;m in the circumferential direction, and the surface roughness (Ra) in the axial direction is 0.15˜0.30 &mgr;m. A relationship between a deviation “P-P” and an innermost dent V is defined as P-P<2.5 &mgr;m and V<1.0 &mgr;m. With the use of synthetic resin (PC, PAR, PPS, e.t.c.), a support block 20 is provided integrally around the rotation shaft 10. The support block 20 tightly engages with the rotation shaft 10 due to a residual stress based on a shrinkage allowance appeared when molding the synthetic resin. With a good deviation “P-P”, a shallower innermost dent V and a smaller surface roughness in the circumferential direction, a stable surface friction is maintained for an extended period time with the least amount of wear. By making the surface roughness (Ra) in the circumferential direction smaller by 0.1˜0.

Abstract: In a frictional hinge device, a metallic shaft has a rotational axis as a rotational center. A support block is made of a synthetic resin so that the support block rotatably supports the metallic shaft relatively. The support block is relatively rotatable in relation with the metallic shaft by a surface friction resistance between the support block and the metallic shaft. A surface treatment imparts Vickers number (Hv) of 800 or more with an outer surface of the metallic shaft. As an alternative, a hardened layer is provided around the outer surface of the metallic shaft and the hardened layer has Vickers number (Hv) of 800 or more with its thickness at least in 5.0 &mgr;m.

Abstract: In a frictional hinge device, a metallic shaft 10 has an axis as a rotational center. A support block 20 is molded in synthetic resin (PC, PAR, PPS or the like) around the metallic shaft 10 so that the support block 20 is relatively rotatable with respect to the metallic shaft 10.The support block 20 is held at any angular position by a surface friction resistance between the support block 20 and the metallic shaft 10. In addition, an outer surface of the metallic shaft 10 is processed with a surface treatment to attain a surface roughness (Ra) ranging from 0.15 to 0.35 m. This ensures a stable surface frictional resistance between the support block 20 and the metallic shaft 10 with minimum scratch and stickslip.

Abstract: In a frictional hinge device a support block 20 is molded in a synthetic resin around the metallic shaft 10 so that the support block 20 is rotatably supported by the metallic shaft 10. The support block 20 is held at any angles by a surface friction resistance between the support block 20 and the metallic shaft 10. The synthetic resin has a modulus of bending elasticity, a changing rate of which is up to 30% at an operating temperature ranging from −20 to 80° C. The support block 20 tightly engages with the metallic shaft 10 due to a residual stress appeared between the support block 20 and the metallic shaft 10 when cooling the synthetic resin to shrink. Due to the smaller changing rate of the modulus of bending elasticity, the surface friction resistance becomes stable between the support block 20 and the metallic shaft 10 under normal ambient temperature with the least amount of friction.

Abstract: In a frictional hinge device, an inequable strain distribution within a synthetic resin is determined to be 15% or less so as to increase a torque holding rate by 80% or more to tightly engage a support block 20 with a metallic shaft 10. This eliminates variations on a frictional torque with no substantial stickslip phenomenon, abnormal noise and initial scratches accompanied when pivotally moving the support block 20 relative to the metallic shaft 10 so as to maintain a stable surface friction resistance with good endurance for a long period of time.

Abstract: In a frictional hinge device, a metallic shaft has a rotational axis as a rotational center. A support block is molded in synthetic resin around the metallic shaft so that the support block is rotatably supported by the metallic shaft relatively. The support block is held at any angular position by a surface friction resistance between the support block and the metallic shaft. A shape factor (W) in relation with the metallic shaft and the support block is defined by the following inequality: 1.5≦W≦3.5, where W={1+(Do/Dh)2}/{1−(Do/Dh)2}, (Do) is a diameter of the metallic shaft, (Dh) is a diameter or its equivalent of the support block.

Abstract: In a push pull type control cable, a conduit has a tubular liner made of a plastic material. A wire is provided by winding a diameter-reduced side wire around a core wire, and arranged to be axially movably placed within the liner. A zinc plating is coated on an outer surface of the side wire, a thickness of the plating ranging from 5.0 &mgr;m to 20 &mgr;m. The core wire is made of a steel, and a diameter of the core wire ranges from 1.2 mm to 1.6 mm. The side wire forms a row of steel lines which are single wound around the core wire at a predetermined lead angle (13 degrees to 25 degrees), a diameter of each of the steel lines ranging from 0.25 mm to 0.60 mm.
