Abstract
An air-conditioning duct structure is included in a vehicular dash beam member. Material for the duct is made of a heat insulating and sound absorbing material and is adhered onto the surface of a sheet material for the beam member which is then bent into a semi-tubular shape so that the material for the duct is positioned inside thereby forming beam member bodies. Beam member bodies are combined by joining their joining surfaces that face each other to thereby form a tubular closed sectional shape. Achieving vibration attenuation, noise absorption and the heat insulating functions with an inner surface sheet member of an air conditioning duct is achievable. An air conditioning duct extending across a vehicle's width is formed by joining a metal reinforcing member and a resin cover. The sheet member is put between the reinforcing member and the cover.
