PROBLEM TO BE SOLVED: To prevent leakage of a coolant.SOLUTION: A cooling structure includes an LED attachment part 52 for attaching a line LED 43, and a cooling pipe engaging part 51 that has a groove part 55 for being engaged with a cooling pipe 22 allowing circulation of cooling water serving as a coolant. A heat-conduction bar 38 transfers heat of the line LED 43 to the cooling pipe 22 through the LED attachment part 52 and the cooling pipe engaging part 51, and makes the heat recovered by the cooling water. 【課題】冷媒の漏れを防止する。【解決手段】ラインＬＥＤ４３を取付けるＬＥＤ取付部５２と、冷媒たる冷却水が流通する冷却管２２が係合する溝部５５を有した冷却管係合部５１と、を備え、前記ラインＬＥＤ４３の熱をＬＥＤ取付部５２、及び冷却管係合部５１を通じて冷却管２２に伝えて前記冷却水に回収させる熱伝導バー３８を構成した。【選択図】図７
