Abstract: A shock absorbing member may include a cylindrical member that is configured to receive an impact load axially applied and to be axially collapsed, a wood member that is received in the cylindrical member while an axial direction of annual rings thereof is aligned with an axial direction of the cylindrical member, and positioning means for positioning axially both end portions of the wood member relative to axially both end portions of the cylindrical member such that a clearance can be formed between an outer surface of the wood member and an inner wall surface of the cylindrical member over an entire circumference thereof. The wood member and the cylindrical member are configured to receive the impact load in an axial direction thereof.

Abstract: An impact absorbing unit for a vehicle which is subjected to an axial compressive force from the impact in the event of a traffic collision, which includes a columnar piece of wood and a metallic housing covering lateral faces of the piece of wood. The housing has an uneven configuration formed in an outer surface or an inner surface, and the housing bulges outwards when subjected to an axial compressive force.

Abstract: A vehicle impact-absorbing member has a columnar wood member and a hollow cylindrical metal frame body covering side-surfaces of the wood member and is configured to axially receive a compression load caused by impact in the event of a collision in an axial direction of wood member. The frame body may have a square cylindrical shape. A ratio of an outer side in a hollow square cross-sectional surface of the frame body to a thickness of the frame body is set to a range of 9-12.

Abstract: A thermoplastic resin composition that may contain plant fine powders that are kicked up when a plant is pulverized. Such plant fine powders have an average particle diameter of 20 ?m or less. Standard deviation of particle diameters are 15 ?m or less. Content of the plant fine powders is less than 50 wt %.

Abstract: An engine cover that is for an automobile and is formed from a molded resin body. The molded resin body includes a thermoplastic resin, plant fiber in which the fiber length is less than 1 mm, and non-plant fiber in which the fiber length is 1-5 mm. The plant fiber content is 1-5% by weight, and the non-plant fiber content is 1-20% by weight.

Abstract: A shock-absorbing member may include a cylindrical member configured to receive an impact load applied axially and capable of being axially compressed by the impact load, a wood member received within the cylindrical member without contacting each other and having an impact load-resistance strength greater than the cylindrical member, and a foam material capable of positioning the wood member with respect to the cylindrical member and filled in a clearance formed between an outer surface of the wood member and an inner wall surface of the cylindrical member partially or over the entirety thereof by foaming. The foamed foam material has a strength that does not prevent the cylindrical member from radially inwardly deforming when the cylindrical member is axially compressed with the wood member by the impact load.
