Abstract: The resin panel of the present invention includes a first structure 15A and a second structure 15B stacked on each other. The structures include reference surfaces that serve as the front surface and the back surface of the resin panel respectively. Each of the structures includes a plurality of protrusions 150a, 150b protruding inwardly from the reference surface. The protrusions 150a of the structure 15A face the protrusions 150b of the other structure 15B each other. Jutting portions Rb of linear shape are formed between adjacent protrusions of each of the structures. The structures 15A, 15B are joined such that apical portions of the protrusions of each structure abut one another.

Abstract: A foam duct in which rigidity is improvable includes a cylindrical portion having an external contour of a polygonal shape and a projection in an inner surface side of the cylindrical portion, and thickness of wall portions of the cylindrical portion is larger in a portion in which the projection is formed than in a portion in which the projection is not formed.

Abstract: A foam duct to which a heat insulating property and a shock absorbing property can be is provided due to structure of the foam duct is a foam duct including foam resin and includes a high-foam wall portion having a higher expansion ratio than other wall portions.

Abstract: The present invention is a molded foam (foam duct (1)) having a tubular section (100a) with an open end (120a). A parting line (PL), which is formed during molding, extends to the open end (120a). The molded foam includes a protruding portion protruding from the parting line (PL) on one side of the parting line (PL) at least in the proximity of the open end (120a).

Abstract: Provided is a luggage compartment structure of a vehicle in which a plate member is able to be installed in various aspects in a luggage compartment of the vehicle, the luggage compartment structure of a vehicle being capable of preventing an article on the plate member from falling using a fall prevention member which is a separate member from the plate member. The luggage compartment structure of a vehicle has a plate member installed in at least two positions including a first position (?) of a luggage compartment of the vehicle and a second position (?) that is higher than the first position (?), and a fall prevention member which prevents an article placed on the plate member installed at the second position (?) from falling, wherein the fall prevention member is detachable from the plate member or the vehicle.

Abstract: An impact absorbing member includes a hollow body having a plurality of ribs, and the hollow body includes a low rib density portion being a portion where density of the ribs is low, and a high rib density portion being a portion where density of the ribs is high. The hollow body may include a thin portion and a thick portion.

Abstract: An impact absorbing member includes: a first wall and a second wall that face each other; a plurality of side walls connecting these first wall and second wall; a corner portion connecting the side walls; and a destruction inducing portion, located within a predetermined area from the corner portion, for destroying the corner portion when the first wall or the second wall receives impact.
