To provide an internal combustion engine for a vehicle which can prevent that a chain case is warped due to stress applied from a tension impartment member, and can prevent that a connecting force between the chain case and an engine main body is lowered.SOLUTION: When setting a space which is surrounded by a first virtual plane face 91 for connecting a front boss part 53A and a rear boss part 53B, a second virtual plane face 92 extending to a fore-and-aft direction while passing a case-side connecting part 51A, a third virtual plane face 93 extending to a vertical direction while passing the front boss part 53A, and a fourth virtual plane face 94 extending to the vertical direction while passing the rear boss part 53B as a bracket arrangement space 96 in which a first mount bracket 46 is arranged, a tensioner connecting part 34a of an auto-tensioner 34 is arranged in the bracket arrangement space 96.SELECTED DRAWING: Figure 9
【課題】張力付与部材から加わる応力によってチェーンケースが撓むことを防止でき、チェーンケースとエンジン本体との連結力が低下することを防止できる車両用内燃機関を提供すること。【解決手段】前側ボス部53Aと後側ボス部53Bとを結んだ第1の仮想平面91と、ケース側連結部51Aを通って前後方向に延びる第2の仮想平面92と、前側ボス部53Aを通って上下方向に延びる第3の仮想平面93と、後側ボス部53Bを通って上下方向に延びる第4の仮想平面94とによって囲まれる空間を第1のマウントブラケット46が配置されるブラケット配置空間96とした場合に、ブラケット配置空間96にオートテンショナ34のテンショナ連結部34aが配置されている。【選択図】図9
