Abstract: A vehicle rear body structure is provided in a vehicle that includes an electrical component box. The vehicle rear body structure includes a rear frame, a protective frame that is positioned on a rear side of the electrical component box and stands erect on the upper surface of the rear frame, a wheel housing reinforcing gusset that includes an engagement pin that protrudes rearward from the rear surface thereof, and an upper load transmitting member that extends forward from the upper end portion of the protective frame to the wheel housing reinforcing gusset. In the vehicle rear body structure, the upper load transmitting member has a positioning hole with which the engagement pin is engaged and includes a fastening extension fastened to the inner side surface of the wheel housing reinforcing gusset.

Abstract: An IPU protection guard includes a pair of left and right upper horizontal members, which extend along a forward and rearward direction on an upper portion of an IPU on both sides in a vehicle width direction of the IPU, a pair of left and right lower horizontal members, which extend along the forward and rearward direction on a lower portion of the IPU on both sides in the vehicle width direction of the IPU, and an X-shaped member which extends in an X shape along a rear surface of the IPU.

Abstract: A steering column hanger beam 21 extended between left and right front pillars 13, 15 for supporting a steering column 65 is constructed as an in-line connected body comprising a driver's side hanger beam 22 having a large diameter cross-section and a front passenger's side hanger beam 60 having a small diameter cross-section.

Abstract: Disclosed is an aqueous dispersion comprising a carboxyl group-containing chlorinated polypropylene with acid value of 10 to 60 and chlorine content of 15 to 35 wt. % and a carboxyl group-containing propylene-.alpha.-olefin copolymer with number average molecular weight of 2000 to 20000 and acid value of 30 to 150, neutralized with basic substance and dispersed into water using nonionic surfactant. It is possible to obtain an aqueous dispersion of chlorinated polypropylene with excellent adhesive property without using organic solvent.

Abstract: An aqueous composition for covering a polyolefin resin substrate consists essentially of a dispersion of a graft copolymer in which from 1 to 20% by weight, based on the graft copolymer of an .alpha.,.beta.-unsaturated dicarboxylic acid or acid anhydride thereof is grafted onto a propylene-.alpha.-olefin polymer, a neutralizing base and a polyol in water.

Abstract: A method of producing organic solvent-soluble chlorinated rubber is disclosed, which is characterized in that, in the method of chlorinating rubber latex with chlorine gas up to 60 to 75% chlorine content in the aqueous medium as it is,(A) nonionic or cationic surfactant is added to rubber latex prior to chlorination and then acid is added to perform the acidifying treatment of latex,(B) rubber latex is chlorinated up to at least not less than 30% chlorine content at a temperature of not higher than 50.degree. C. blocking off the light in the first step of chlorination, and(C) remaining chlorination is performed while irradiating ultraviolet rays in the second step of chlorination. The chlorinated product is also claimed.
