Claim:
A gas turbine combustor comprising: burners whose discharge ports open into a combustion chamber; and pre-mixture injection tubes which inject a mixture of fuel and air into said combustion chamber, wherein said mixture that is supplied from said pre-mixture injection tubes is injected into burned gas of a mixture discharged from said burners, and mixed with said burned gas to react, wherein said pre-mixture injection tubes include a flow-deflecting body which turns said mixture to one side at outlet ports of said pre-mixture injection tubes in order to inject said mixture into said burned gas to react, and wherein said flow-deflecting body is a bridge body that is installed across said pre-mixture injection tubes, and said bridge body has a wall surface with a U-form or V-form cross sectional shape in which the sharp edge faces upstream in order to split said mixture and simultaneously turn the mixture to one side.
