Claims

[Scope of utility model registration request]

In a gas turbine in which a plurality of rotor blades are attached in the circumferential direction of a rotating disk, a tapered attachment portion that decreases from an upstream side to a downstream side is formed on the rotor blade, and the attachment portion is connected to the attachment portion. A gas turbine rotor blade attachment mechanism, wherein the plurality of rotor blades are attached to the disk by inserting the rotor blades into a disk-side attachment portion formed on the disk in accordance with the above.
