Claim 0:
1. A rotary machine comprising:
a rotary shaft that rotates around an axis;
rotor blades disposed in a circumferential direction on an outer peripheral side of the rotary shaft, each of the rotor blades comprising:
a blade root attached to the rotary shaft;
a platform disposed radially outward of the blade root; and
a blade main body extending radially outward from the platform; and

damper members, each of which is disposed radially inward of the
platform between adjacent ones of the rotor blades, wherein the platform includes:
a first end surface that faces a first side in the circumferential direction and extends radially, and
a second end surface that faces a second side in the circumferential direction such that the second end surface faces the first end surface of an adjacent platform and extends toward the first side in the circumferential direction while extending radially outward, and

each of the damper members comprises:
a first damper disposed on the first end surface and having a first abutting surface,
a second damper that has a second abutting surface slidably abutting the first abutting surface of the first damper and is abuttable on the second end surface, and
an elastic member that bonds the first damper to the second damper.
