PURPOSE:To enhance the cooling effect by composing a partition unit which is provided on the inner periphery of a stator in an air gap of a stationary side baffle and a movable side baffle, thereby preventing the recirculation of high temperature gas. CONSTITUTION:A partition unit 20 which is provided on the inner periphery of an air gap is composed of a stationary side baffle 21, a movable side baffle 22, a rack 23 and a pinion 24. The baffle 21 is entirely formed substantially in a C shape, notches 26 are formed on the inner and outer peripheral surfaces which are connected to both side opening ends of the notch 25, and a guide groove is formed along the circumferential direction at the inside surface. The baffle 22 is composed of two semicircular rings 22A, 22B telescopic to the interior from both end openings of the baffle 21. |
