The present invention relates to a reducer for a vehicle, which comprises: a worm wheel which is disposed in a gear housing, and of which inner circumferential surface is coupled to a steering shaft; a worm shaft of which outer circumferential surface has worms to be engaged with the worm wheel; and a heat radiation member having a gear unit, located at one side of the worm shaft in a plate-shape to radiate heat of the worm shaft, engaged with the steering shaft to be rotated, protruding between the worms on a surface facing the worm shaft to be spaced from the worms so as to be maintained in a state of being spaced from the worms. Therefore, heat in the worm shaft and the gear housing can be radiated.
본 발명은 자동차의 감속기에 관한 것으로, 기어하우징 내측에 구비되며 내주면에 조향축이 결합되는 웜휠, 외주면에 웜이 형성되어 웜휠과 맞물리는 웜축, 웜축의 열을 방열시키도록, 판형상으로 형성되어 웜축의 일측에 위치되며 조향축과 치합되어 회전되고, 웜축과 마주보는 면에서 웜 사이로 돌출 형성되되 웜과 이격되게 돌출 형성되어 웜과 이격된 상태를 유지하는 기어부가 구비되는 방열부재를 포함하여 웜축 및 기어하우징 내부의 열을 방열시킨다.
