ABSTRACT:
Embodiments in accordance with the present invention relate to greatly decreasing vibrations of a rotary disk at a portion where vibration on the disks is to be suppressed in a vibration-suppressing mechanism for rotary disks while enabling the rotary disks to be incorporated in the shroud surface. In one embodiment, the vibration-suppressing mechanism for rotary disks comprises at least one rotary disk and a shroud surface extending along and facing the outer circumferential edges of the disk. The shroud surface is so formed as to possess a portion where a gap between the outer circumferential edge of the disk and the shroud surface becomes small near a portion where the vibration of the disk is to be suppressed.
