摘要： A scissors gear constituting a part of a gear train and seizing and holding by pressure teeth of a gear meshing therewith in order to restrain gear butting noises, comprises: a first cylindrical gear whose tooth trace is not parallel to an axis thereof; a second cylindrical gear whose tooth trace is not parallel to an axis thereof, the second gear being slidable in an axial direction; and a biasing member for making said first gear and said second gear apart from or close to each other in the axial direction. In an alternative embodiment, the teeth of the first and second cylindrical gears are parallel to the respective axes of the gears. The scissors gear is particularly suited to incorporation in a gear train that transfers a driving force from an electric motor to a steering drive component of an electric power steering apparatus.

摘要： A gear part of the present invention includes a lubrication coating formed on a surface of the gear part, the lubrication coating containing an organic phosphorous compound. In the gear part, when a tooth surface of the gear part is engaged with a tooth surface of a counter member, the organic phosphorous compound is transferred to the tooth surface of the counter member and another lubrication coating containing the organic phosphorous compound is formed on the tooth surface of the counter member. As a result, the lubrication coating can be held on the surface of the gear part for long periods.
