A resin additive for a polyphenylene sulfide includes a diamine compound expressed by a following general chemical formula, in which A is an oxygen atom or a sulfur atom, X is a hydrogen atom, an alkyl group with a carbon number of six or less, or an aryl group, and n is a natural number of 1 to 10. The rear seat is attached to the floor of the vehicle by a first linkage so that the seat pan of the rear seat can translate forward to be housed, in a forward position, in a space provided for this purpose below the location which is occupied by the seat pan of the front seat in the normal utilization position of the said front seat. An integral mounting support extends from at least one edge of the stone body. When the clock signal or inverted clock signal is at the second level, they generate an intermediate potential between the first and second reference potentials. A second yoke having a face that extends parallel to the lamellae adjoins the outermost lamella on both sides, \u201coutermost\u201d being in relation to the axial direction. This system restores regenerative braking without causing the regenerative braking to trigger a subsequent ABS event.
