Claim:
1. A thrust vectoring apparatus comprising: a nozzle having a nozzle output opening which emits a combustion gas in a rear direction; a jet tab arranged on a rear side of the nozzle; a rotation shaft connected to the jet tab to be rotatable around a rotation axis; a driving mechanism configured to rotate the rotation shaft around the rotation axis; and a gas seal member arranged on an outer circumferential surface of the rotation shaft to prevent the combustion gas from invading the driving mechanism, wherein the jet tab is configured to rotate in a plane which intersects with a longitudinal center axis of the nozzle, by rotating the rotation shaft around the rotation axis, and to move from a standby position where the jet tab does not overlap with the nozzle output opening, to an operation position where the jet tab overlaps with the nozzle output opening, wherein a first gap is formed between the jet tab and a surface of a rear end surface of the nozzle, and wherein the rotation shaft has a protrusion arranged on a rear side of the gas seal member, and the protrusion protrudes in a radial direction from the rotation shaft.
