<p>In the variable stator blade drive device of the axial flow machine according to the present invention, a ring support mechanism (40), which supports a movable ring (31), is provided with: first rollers (41); first support sections (44), which support the first rollers so as to be unable to move relative to a stator blade-holding ring (20) in the radial direction (Dr) or the axial direction (Da); second rollers (51); second support sections (54), which support the second rollers so as to be able to move relative to the stator blade-holding ring in the radial direction and which energize the second rollers in the radial direction; a third roller (61), which allows relative movement of the movable ring in the radial direction while restricting relative movement of the movable ring in the axial direction; and a third support section (64), which supports the third roller so as to be unable to move relative to the stator blade-holding ring in the axial direction or the radial direction.</p> |
