Abstract: A yoke member includes a primary yoke and a secondary yoke which are opposed to each other. The primary yoke is configured such that a maximum width of a widest portion of each of a plurality of primary teeth of the primary yoke is smaller than a minimum width of a narrowest portion of a primary ring plate of the primary yoke. The secondary yoke is configured such that a maximum width of a widest portion of each of a plurality of secondary teeth of the secondary yoke is smaller than a minimum width of a narrowest portion of a secondary ring plate of the secondary yoke.

Abstract: A flat cable includes at least two conductors offset from and in parallel with one another, and an insulating covering disposed over a periphery of the conductors. The insulating covering includes a vinyl chloride-based resin composition with a brittle temperature from ?40° Celsius to ?25° Celsius, a hardness D from 35 to 55, and heating deformation of 10% or below. The vinyl chloride-based resin composition substantially contains only vinyl chloride homopolymer as the resin component.

Abstract: The invention is provided to a flat cable having a thinner insulating covering while keeping sufficient wear resistance and low temperature resistance. The invention provides a flat cable, which includes at least two conductors disposed apart from each other and in parallel to each other, and an insulating covering disposed over a periphery of the at least two conductors, and formed of vinyl chloride-based resin composition having a brittle temperature of from ?40 Celsius degrees to ?25 Celsius degrees, an hardness D of from 35 to 55, and heating deformation of 10% or below.
