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. |
