To suppress membrane vibration of a front cover of an internal combustion engine.SOLUTION: An internal combustion engine side mount bracket (6) is attached to an internal combustion engine body (8). A bolt boss (32) of the internal combustion engine side mount bracket (6) goes through a boss through hole (13) of a front cover (5). A part of an outer peripheral surface on a distal end side of a second bolt boss (32b) is pressed against an inner peripheral surface of a boss through hole (13a) over the full circumference on a rear surface side of the front cover (5). A part of an outer peripheral surface on a distal end side of a fifth bolt boss (32e) is pressed against an inner peripheral surface of a boss through hole (13b) over the full circumference on the rear surface side of the front cover (5).SELECTED DRAWING: Figure 7

    【課題】内燃機関のフロントカバーの膜振動を抑制する。【解決手段】内燃機関側マウントブラケット(6)は、内燃機関本体(8)に取り付けられている。フロントカバー(5)のボス部貫通孔(13)は、内燃機関側マウントブラケット(6)のボルトボス部(32)が貫通する。第2ボルトボス部(32b)は、フロントカバー(5)の裏面側で、その先端側の外周面の一部が全周に亘ってボス部貫通孔(13a)の内周面に押し当てられている。第5ボルトボス部(32e)は、フロントカバー(5)の裏面側で、その先端側の外周面の一部が全周に亘ってボス部貫通孔(13b)の内周面に押し当てられている。【選択図】図7
