The present invention relates to a double injection steering wheel for a vehicle having a heating function, wherein a hot wire pad is arranged between a first foaming layer and a second foaming layer. More specifically, the present invention relates to a double injection steering wheel for a vehicle having a heating function, wherein when forming the first foaming layer, a protrusion is formed at one side of a parting line of upper and lower molds for a protruding layer caught in the protrusion to be formed at an internal side of the second foaming layer. Therefore, the second foaming layer is prevented from spinning with no traction.
본 발명은 1차 발포층과 2차 발포층 사이에 열선 패드가 배치되는 이중 사출용 발열 구조를 갖는 스티어링 휠로서, 특히 1차 발포층을 성형할 때 상하 금형의 파팅라인 중 어느 일측에 단턱을 형성시켜 2차 발포층의 내측에 단턱에 걸리는 걸림층을 형성시켜 2차 발포층의 헛돌아가는 것을 방지하는 이중 사출용 발열 구조를 갖는 스티어링 휠에 관한 것이다.
