Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for molding a coating member in such a way to wrap wood by injection molding while avoiding damage as much as possible to the wood having a desired shape.SOLUTION: A method for producing a vehicle member comprises: a first step of fitting wood 6 onto a holding pin 33 and holding the wood inside a cavity in a floating manner; and a second step of ejecting a molding material into the cavity from first ejection ports 41a and 41b provided on an upper side of the wood 6 and second ejection ports 42a and 42b provided on a lower side of the wood 6 positioned, respectively, offset outwardly with respect to an outer periphery of the wood 6, and causing the molding material ejected from the first ejection ports 41a and 41b and from the second ejection ports 42a and 42b to converge together at a side face 20b of the wood 6.SELECTED DRAWING: Figure 7 【課題】所望の形状を備えた木材の破損を極力回避しつつ、射出成形によって木材を包むように被覆部材を成形することにある。【解決手段】第一工程:木材6を保持ピン33に挿嵌してキャビティ内に浮かせた状態で保持する。第二工程:木材6の上端側に設けられている第一射出口41a,41bと、木材6の下端側に設けられている第二射出口42a,42bとが、それぞれ木材6の外周より外側にオフセットした位置からキャビティ内に成形材料を射出し、第一射出口41a,41b及び第二射出口42a,42bから射出した成形材料を木材6の側面20bで合流させる。【選択図】図7
