PURPOSE:To uniformly distribute circumferential stress of a disk in the axial direction thereof by alternately laminating disks having female faucet parts and having female faucet parts at the opposed ends thereof. CONSTITUTION:Each of disks 1 constituting a laminant rotor is formed by such a manner that disks 1' having male faucet parts 1a and disks 1'' having female faucet parts 1b at the axially opposed ends thereof are alternately laminated and tightly joined with each other by use of bolts 3 of which each passes through a connecting hole 1c. Stress in the circumferential direction of the disks 1 may therefore be distributed uniformly in the axial direction. |
