The downstream end part of the exhaust pipe is linear, and protrudes to the inside of the casing. Moreover, the downstream end part of the exhaust pipe has: an inclined opening that opens along a surface that is inclined with respect to a surface that is perpendicular to the center axis of the downstream end part of the exhaust pipe; and a shielding part for blocking the exhaust flow path. Furthermore, the inclined opening is positioned at the top side of the shielding part in the perpendicular direction.
