Abstract The purpose of the present invention is to provide a turbine that allows deterioration of performance to be suppressed when opening/closing valves are closed and the man-hours for designing an inner casing and manufacturing cost to be suppressed. Provided is a turbine that is equipped with: turbine rotor blades (4); an inner casing (21) and an outer casing (22) that form an exhaust gas flow path; bypass sections (50) that are provided on the outer periphery of the inner casing (21) and outer casing (22) and form bypass flow paths (52) for leading the exhaust gas to an exhaust gas outlet (28a) so as to bypass the turbine rotor blades (4); and opening valves (51) for opening/closing the bypass flow paths (52). L'objectif de la présente invention est de fournir une turbine qui permet à la dégradation de performance d'être supprimée lorsque des soupapes d'ouverture/fermeture sont fermées et de supprimer les heures de travail pour la conception d'un boîtier interne et le coût de fabrication. L'invention concerne une turbine qui est équipée de : des pales de rotor de turbine (4) ; un boîtier interne (21) et un boîtier externe (22) qui forment un trajet d'écoulement de gaz d'échappement ; des sections de dérivation (50) qui sont ménagées sur la périphérie externe du boîtier interne (21) et du boîtier externe (22) et forment des trajets d'écoulement de dérivation (52) pour envoyer le gaz d'échappement vers une sortie de gaz d'échappement (28a) de façon à contourner les pales de rotor de turbine (4) ; et des soupapes d'ouverture (51) pour ouvrir/fermer les trajets d'écoulement de dérivation (52).
