Abstract
A projecting part is formed on an inner circumferential wall surface of a nacelle so that the projecting part projects inward in a diametral direction and extends from a front edge of each of circumferentially-oriented side faces of a bottom pylon. The shape of the projecting part seen from an inner side of the diametral direction is a streamline shape extending in parallel with an engine shaft direction. An apex part at the center of the projecting part is positioned on a rear edge of the bottom pylon.
