PROBLEM TO BE SOLVED: To restrain the temperature rise of a bearing metal by enhancing the heat dissipation performance of the bearing metal.SOLUTION: A bearing housing (60) comprises: a cylindrical bearing metal (61) that rotatably supports a crankshaft (23); a housing body (65) fixed to a casing (11); a ring member (62) provided between the bearing metal (61) and the housing body (65) to fix the bearing metal (61) to the housing body (65). The ring member (62) is formed of a metal material having higher heat conductivity than that of the housing body (65).SELECTED DRAWING: Figure 3 【課題】軸受メタルの放熱性を高めることで軸受メタルの温度上昇を抑える。【解決手段】軸受ハウジング（60）は、クランク軸（23）を回転自在に支持する筒状の軸受メタル（61）と、ケーシング（11）に固定されたハウジング本体（65）と、軸受メタル（61）とハウジング本体（65）との間に設けられて軸受メタル（61）をハウジング本体（65）に固定させるリング部材（62）とを有する。リング部材（62）は、ハウジング本体（65）よりも熱伝導率の高い金属材料で形成されている。【選択図】図３
