摘要： PROBLEM TO BE SOLVED: To prevent leakage of sealing air from the inside of a first stage stationary blade by notching a part contacting with a stationary blade support ring in a straight line shape in both lower end parts of a circular arc shape of a flange, and notching a part contacting with a flange side surface in a straight line shape in a circumferential end part of the stationary blade support ring. SOLUTION: A recess part 24 is formed on the circumferential end part of a circular stationary blade support ring 23 by respectively notching a part with which a rear flange 22 of a stationary blade 31 comes into contact. A recess 25 is also respectively formed in the rear flange 22. That is, the recess part 25 is formed in the rear flange 22 of the stationary blade 31, and a seal structure by combining this rear flange 22 and the stationary blade support ring 23 having the recessed part 24 is adopted. Therefore, even if blades relatively fall down in a first stage stationary blade 31 by thermal stress, a seal surface can be reliably held without generating a clearance on a contact surface, and leakage of sealing air from the inside can be prevented.
