CYLINDER HEAD AND INTERNAL COMBUSTION ENGINE

To easily circulate a cooling liquid to a part comparatively far away from a water passing port in which the cooling liquid flows in a water jacket of a cylinder head.SOLUTION: A water jacket 7 has a first water passing port 11 in which a cooling liquid flows, a second water passing port 12 from which the cooling liquid flows out, and a body portion 13 that connects the first water passing port 11 and the second water passing port 12, and in which the cooling liquid flows. The body portion 13 has a first end portion 13a provided with a first water passing port 11, a second end portion 13b on the opposite side to the first end portion 13a, and a third end portion 13c provided with a second water passing port 12. The second end portion 13b is provided with a projecting portion 13e projecting out to the opposite side to the first end portion 13a.SELECTED DRAWING: Figure 1 【課題】シリンダヘッドのウォータージャケットにおいて冷却液が流入する通水口から比較的遠く離れた部位へ冷却液を流通しやすくする。【解決手段】ウォータージャケット７は、冷却液が流入する第１通水口１１と、冷却液が流出する第２通水口１２と、第１通水口１１と第２通水口１２とを接続し、冷却液が流れる本体部１３と、を有する。本体部１３は、第１通水口１１が設けられた第１端部１３ａと、第１端部１３ａの反対側の第２端部１３ｂと、第２通水口１２が設けられた第３端部１３ｃと、を有する。第２端部１３ｂに第１端部１３ａとは反対側に突出した凸部１３ｅが設けられている。【選択図】図１
