摘要： The present invention provides a plated steel material, said plated steel material having a plated layer which contains Al of 4% or more in mass, excellent in surface smoothness even when a cooling rate is low. In the present invention: a plated layer which contains Al of 4% or more in mass and has an Al-type intermetallic compound in an Al phase or abutting on an Al phase is formed on the surface of a steel material; in particular, high corrosion-resistance is secured in various environments by using a plated layer containing Al of 4 to 20% and Mg of 1 to 10% in mass with the balance consisting of Zn and unavoidable impurities or a plated layer containing Al of 4 to 20%, Mg of 1 to 10% and Si of 0.001 to 2% in mass with the balance consisting of Zn and unavoidable impurities; said plated layer contains an intermetallic compound having a melting point of 600° C. or higher by 0.001 to 0.5% in mass; and a plated steel material having an excellent surface smoothness is obtained by using an Al-type intermetallic compound wherein at least one of the lattice constants is in the range from 3 to 5 Å.

摘要： Synthetic resin shaft and gear portions are molded to be capable of slipping each other. During a normal timepiece operation, the shaft and gear portions are integrally rotated. During a hand setting operation, the shaft portion is rotated with slip on the gear portion. In this slip structure of a timepiece, at least one of the shaft and gear portions is formed of an oil-containing resin material.

摘要： An electric power steering apparatus comprises a driving gear driven by an electric motor for steering assist and a driven gear meshed with the driving gear. A steering shaft is rotated along with the driven gear. The steering shaft is rotatably supported by a first bearing and a second bearing. An urging member is arranged in a recess provided in a housing. The urging member urges at least one of the first bearing and the second bearing in a direction in which a center-to-center distance between the driving gear and the driven gear increases.

摘要： An electrical connector is to be connected to a flat conductive member. The electrical connector includes a housing; a terminal held in the housing; and a pressing member supported on the supporting portion to be rotatable for pressing the flat conductive member against the terminal. The terminal includes a base portion, a contacting arm extending from the base portion, and a supporting portion facing the contacting arm. The contacting arm is arranged to form a space for receiving the flat conductive member between the contacting arm and the supporting portion. The contacting arm includes a first contacting portion and a second contacting portion. The first contacting portion is situated at a position closer to the supporting portion than the second contacting portion. The second contacting portion is situated at a position closer to the base portion than the first contacting portion.

摘要： An electric power steering apparatus comprises a transmission mechanism having a drive gear and a driven gear. One end of the drive gear is supported by a bearing hole in a housing through a bearing and a curved plate spring. The curved plate spring comprises a main body surrounding the bearing and at least one crank-shaped elastic tongue supported by at least one of ends of the main body. A recess formed on an inner peripheral surface of the bearing hole has a bottom and a pair of inner wall surfaces opposed to each other in the circumferential direction of the bearing hole. A relief portion for avoiding contact with a connection portion of the elastic tongue is formed between at least one of the inner wall surfaces and the inner peripheral surface of the bearing hole. A boundary between the relief portion and the inner peripheral surface of the bearing hole is engaged with the main body of the curved plate spring, to restrict the movement of the main body in the circumferential direction.

摘要： Deep groove ball bearings are used as bearings supporting both side portions of a worm. In the first bearing on the side of a motor, the curvature radius of a raceway groove in an inner ring or the curvature radius of a raceway groove in an outer ring are set to a specific numerical range with respect to the diameter of a ball.
