Abstract
【解決手段】低温時に潤滑油を昇温させる場合は、軸受保持部13におけるラジアルすべり軸受30の外周側のうち、熱容量の大きい軸受保持部本体20における半割り軸受メタル31Aの外周側では熱媒体流路32の加熱媒体から熱を供給せずに、熱容量の小さいキャップ21における半割り軸受メタル31Bの外周側で熱媒体流路32の加熱媒体から熱を供給する。これによって、熱媒体流路32の加熱媒体から供給された熱が熱容量の大きい軸受保持部本体20に拡散するのを抑えることができ、熱媒体流路32の加熱媒体から供給された熱量のうち、ラジアルすべり軸受30とクランクジャーナル18間の隙間に供給される潤滑油の昇温に利用される熱量の割合を大きくすることができる。
