| description | To prevent the heat elongation of an outer peripheral wall of a scroll from becoming unacceptable.SOLUTION: In a turbine housing 30, a part of a scroll outer peripheral wall 73 is provided with a thermal expansion allowance part 75 that is initially in a contracted state and expands when it thermally expands, and is configured to allow the thermal expansion of the scroll outer peripheral wall 73. According to this, for example, when a scroll flow path forming plate 65 is heated by the heat of exhaust gas flowing through a turbine scroll flow path 35, the thermal expansion allowance part 75 allows the thermal expansion of a first scroll outer peripheral wall 66. Therefore, it is possible to prevent the thermal elongation of the first scroll outer peripheral wall 66 from becoming unacceptable.SELECTED DRAWING: Figure 2
【課題】スクロール外周壁の熱伸びが許容されなくなってしまうことを抑制すること。【解決手段】タービンハウジング３０は、スクロール外周壁７３の一部に、初期は縮められた状態であるとともに熱膨張すると伸びて、スクロール外周壁７３の熱膨張を許容するように構成された熱膨張許容部７５を備えた。これによれば、例えば、スクロール流路形成プレート６５が、タービンスクロール流路３５を流れる排ガスの熱によって暖められると、熱膨張許容部７５によって、第１スクロール外周壁６６の熱膨張が許容される。したがって、第１スクロール外周壁６６の熱伸びが許容されなくなってしまうことが抑制される。【選択図】図２ |
