Claim 4:
5. The liquid fuel injector according to claim 1,
wherein a radially inner boundary of the inner air passage on a downstream side of the inner swirlers and a radially outer boundary of the inner air passage on the downstream side of the inner swirlers have a constant diameter along a direction of the central axis at least at a portion at which the radially inner boundary and the radially outer boundary face each other in a radial direction, and
a radially inner boundary of the outer air passage on a downstream side of the outer swirlers and a radially outer boundary of the outer air passage on the downstream side of the outer swirlers have a constant diameter along the direction of the central axis at least at a portion at which the radially inner boundary of the outer air passage on the downstream side of the outer swirlers and the radially outer boundary of the outer air passage on the downstream side of the outer swirlers face each other in the radial direction.
