To inhibit freezing of an outer cover covering a lamp easily.SOLUTION: A vehicle lamp fitting according to an embodiment of the invention includes: a lamp provided at an operating machine and having a light source; a housing which houses the lamp; an outer cover which covers the lamp with the housing; a transmission pipe which has a hollow interior and transmits heat flow generated from a prime mover provided at the operating machine; and a radiation part which radiates the heat flow transmitted by the transmission pipe to the outer cover. Further, the transmission pipe supplies exhaust air exhausted from the prime mover to the radiation part and transmits the hot flow generated by the prime mover. The radiation part discharges the exhaust air supplied from the transmission pipe to the outer cover and radiates the hot flow to the outer cover.SELECTED DRAWING: Figure 1

    【課題】ランプを覆うアウターカバーの凍結を容易に抑止する。【解決手段】本発明の一態様に係る車両用灯具は、作業機に設けられ、且つ、光源を有するランプと、ランプを収容するハウジングと、ハウジングとともにランプを覆うアウターカバーと、内部が中空であり、且つ、作業機に設けられた原動機から発生した熱流を伝達する伝達管と、伝達管が伝達した熱流をアウターカバーに放射する照射部と、を備えている。また、伝達管は、原動機から排出された排気を照射部に供給して、原動機が発生させた熱流を伝達し、照射部は、伝達管から供給された排気をアウターカバーに放出し、アウターカバーに熱流を照射する。【選択図】図1
