PROBLEM TO BE SOLVED: To provide a sealing device for preventing the leakage of fluid from the internal of a gas turbine engine, particularly from a turbine part. SOLUTION: A turbine module 18 has fixed vane stages 100, 102 and rotating turbine blade stages 74, 76. The blade stages 74, 76 are located apart from the vane stages 100, 102, between which an annular chamber is formed. Pressure fluid is supplied to a chamber 140 by a manifold 126. Outer and inner diameter sealing means including a cover plate 180 which is arranged near the vane stages 10, 102 and the blade stages 74, 76 or seal joined thereto prevent the leakage of the pressure fluid. A flow guide baffle 146 divides the chamber to form a stationary chamber 147 and a rotary chamber 140. Thus, the leakage of the fluid from the turbine module 18 is prevented.
