An agent for providing an electrostatic coating property and improving the water resistance of a coating film comprises 100 weight parts of an aromatic ring-containing polyetheresteramide (A) derived from a polyamide having carboxyl groups at both ends and having a number average molecular weight of 500 to 5,000 and an alkylene oxide adduct of bisphenols having a number average molecular weight of 1,600 to 3,000; and 5 to 100 weight parts of a vinyl copolymer comprising as essential constituent units a vinyl monomer (b1) having a sulfonic acid (or sulfonate) group and at least one monomer (b2) selected from vinyl monomers having a functional group that is reactive with (A). Thus, an agent for providing an electrostatic coating property and improving the water resistance of a coating film that allows electrostatic coating immediately after molding without the coating of a conductive primer for under coating in electrostatically coating a styrene-based resin molded article and provides an excellent water resistance for a coating film after coating, and an electrostatically coated resin molded article using the same are provided.

A three-wheeled automobile comprises a front cowl for enclosing a front portion of the automobile, and a floor forming a passenger step. The front cowl has on lateral sides thereof rear ends positioned above front wheels of the automobile, and a front end surface positioned forwardly of the front wheels. As a result, a large space is provided between a front wall of the front cowl and a seat. A handle post is provided generally centrally of the floor. The floor has roomy foot platforms located around the handle post. As a result, a space left forwardly of the handle post can be used as a feet accommodating area.

The method for molding a resin reinforced with fiber wherein a resin sheet reinforced with fiber is positioned juxtaposed a face of a mold, which is either one of a female mold or a male mold, and then hardened, but before molding, modifying the viscosity to different levels in different portions of the resin sheet. Thus, it is possible to surely prevent occurrence of a partial difference in thickness of the moldings or, if necessary, to partially change these thicknesses according to predetermined values.

The object of the present invention is to cool forcibly the upper and the lower clamp portions of the parson using the upper and the lower blow holes of respective needle blow nozzle synchronously, the metallic mold is cooled by using the cooling apparatus inside the wall, thereby shorten molding cycle time and stabilize the quality. The blow molding method and apparatus, and metallic mold and needle blow nozzle of the present invention are constructed so that an upper and a lower needle blow nozzles (1a, 1) are inserted into said parison (59) to cool respective clamp portion (59c, 59d) forcibly, the discharge nozzle (1b) discharge air, and the molding parson (59) in the internal side of the metallic mold (40A) is cooled by the cooling apparatus (600) disposed inside of the metallic mold (40A), so as to shorten molding cycle time.

A light vehicle includes a lid that is pivotable about a hinge, provided at the rear end of the lid, for opening and closing a rear trunk. Locking members are provided at the front end of the lid, which are releasably engageable with roof-supporting struts. Thus, the lid can be moved to a fully open position without being interfered by the presence of the struts, which allows the rear trunk to be operated and used with increased ease. The seat, including a seating section and a back rest section integrally formed together, has an inclined lower surface that is superposed on an inclined upper surface of a rear cowl. Thus, rearward force applied to the seat when the vehicle starts moving or accelerating is divided to allow the seat to be firmly pressed downward.
