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 device for electronically transforming displacement of automobile accelerator lever, an accelerator pedal and a return member are provided, the latter of which returns the accelerator lever back to an original position. A detector device is provided to detect a displacement of the accelerator lever to generate an electrical signal. The detector device has a magnetic plunger which mechanically moves in association with the accelerator lever, and further has primary and secondary coils to surround the magnetic plunger so that the magnetic plunger mechanically moves therethrough. The primary coil is energized to detect an electromotive force produced from the secondary coil. A housing encloses the plunger, and the primary and secondary coils. An engagement piece is fixed to the accelerator lever to actuate a switch which detects whether or not the accelerator pedal is stepped.

Abstract: An improved cable end structure, including a guide member 5 comprising a plate-like portion 7 disposed between the cable end device b and the cushion 3, and a tubular portion 6 formed integrally with the plate-like portion 6 so that the guide member 5 may prevent the pull-cable a from contacting the cushion 3. The plate-like portion 7 is disposed between the cable end device b and the cushion 3 which allows the tubular portion 6 to be held in the cushion 3 and the tubular portion 6, in turn, prevents the pull-cable a from contacting and abrading the cushion 3.

Abstract: In an anti-vibration resin structure for outer cable end, a casing cap (10) is provided in which an end of an outer cable (3) of a control cable (2) is placed to teleoperate a device. An anti-vibration cushion (20) is molded around the casing cap (10) to absorb vibration from the outer cable (3). A shield cushion (30) is molded around the anti-vibration cushion (20) so as to fasten it to a partition of a motor vehicle. A polyamide material is used to the shield cushion (30), a crystallization degree of the polyamide material falls in the range of 16.about.25%. This retains the predetermined characteristics with the anti-vibration cushion (20), and thus insuring the anti-vibration cushion (20) with a stable vibration absorption property.

Abstract: A ball joint having a ball stud provided with an integral spherical portion at one end thereof. A unitary molded synthetic resin body forms a molded holder having a concavity in which the spherical ball portion is tightly held disposed rotatable omnidirectionally and tiltable therein. The concavity has an opening of a lesser diameter than a maximum diameter of the concavity so that the spherical portion of the ball stud can be pressure-fitted into the concavity with the ball stud extending axially laterally of the molded holder. A link rod having a circular annular end held by the molded holder extends laterally of the holder defining in assembly with the ball stud a ball joint. The annular end is embedded in the synthetic resin of the molded holder and has an internal diameter substantially coaxial with the ball stud and greater than the diameter of ball stud spherical portion so that the synthetic resin concavity and the spherical ball portion have opposed smooth surfaces.
