Patent number: 9132778Abstract: A movement mechanism of a luggage board for dividing a vehicle luggage compartment into upper and lower parts. Sidewalls on either side of the luggage compartment are each provided with a guide part for guiding guide protrusions when a luggage board moves between the upper and lower positions and a support part for supporting the luggage board. The guide part has a lower guide section inclined such that a vehicle rear side thereof is positioned above a vehicle front side thereof and an upper guide section extending toward the front of the vehicle from the end of the lower guide section on the vehicle rear side. The support part is provided on each sidewall of the luggage compartment more toward the rear of the vehicle than an intersection part between the lower guide section and the upper guide section on the vehicle rear side.Type: GrantFiled: February 14, 2013Date of Patent: September 15, 2015Assignees: Nissan Motor Co., Ltd., Kasai Kogyo Co., Ltd.Inventors: Shoichi Yoshizawa, Atsushi Akiba, Masatoshi Yamashita, Shigehiro Okada

Patent number: 4866134Abstract: An electric metal foil-plated laminate sheet which is obtained by laminating a cured layer of a thermosetting resin composition with electroconductive foils, said thermosetting resin composition comprising 30-85% by weight of (A) a rubber-modified vinyl ester obtained by reacting,(a) an epoxy resin,(b) a carboxyl group containing rubbery polymer derived from a conjugated diene, and(c) at least one unsaturated monocarboxylic acid selected from the group consisting of acrylic acid and methacrylic acid to react one another in amounts such that, based on 100 parts by weight of (a) the epoxy resin, (b) the carboxyl group containing rubbery polymer accounts for a proportion in the range of 5 to 80 parts by weight and that the total number of carboxylic group contained in (b) the rubbery polymer and (c) the unsaturated monocarboxylic acid falls in the range of 1.3 to 1.5 per each of the epoxy groups contained in (a) the epoxy resin at a temperature of 90.degree. to 120.degree.
