    摘要： A polyurea resin molding composition for RIM use comprising (a) polyoxyalkylenpolyamine having an average molecular weight greater than about 400 and a plurality of terminal primary or secondary amino groups, (b) an aromatic polyamine and/or xylylenediamine and (c) a polyisocyanate. The component (a) contains dispersed therein a polymer prepared by the in situ polymerization of at least two different olefinically unsaturated monomers in the presence of a radical polymerization initiator, the ratio of the average amino equivalent of said polyamines (a) and (b) in combination to the average NCO equivalent of said polyisocyanate (c) being between about 1:0.7 to 1:1.5.

    摘要： To obtain a fuel filler structure for a fuel tank wherein when causing an opening and closing valve to close, it can be ensured that the opening and closing valve does not rapidly rotate to a closed position in which it closes a fuel fill inlet, and when causing the opening and closing valve to open, the opening and closing valve can be opened with a small force. A fuel filler structure is equipped with a damper on the near side of a flapper valve in the insertion direction of a fuel nozzle. When the flapper valve rotates to an open position, the damper does not act on the flapper valve, and when the flapper valve rotates to a closed position, the damper acts on the flapper valve.
