PURPOSE:To improve heat radiating efficiency due to the large surface area and simply fit it to a pump, a reservoir, and the like in addition to a return pipe part without fixing by welding or the like, concerning a heat radiating device to cool high temperature oil circulated in a power steering unit. CONSTITUTION:The heat radiating device for power steering unit is constructed so that a belt-like member 1 constituted of a heat radiating member 3 of metallic belt formed with many radiating fins 4 on the side and a holding member 2 to hold the heat radiating member 3 on the surface of a return pipe 27 and the like by press-fixing force, is helically wound on the surface of the return pipe 27, a reservoir, and the like, and the heat radiating member 3 is fixed only by the press-fixing force of the holding member 2. |
