PURPOSE: A reaction type turbine apparatus is provided to form the second body part of a rotary part with a material having a specific gravity lower than that of the first body part of the rotary part in order to reduce the weight of the rotary part, thereby preventing the increase of the diameter of a rotary shaft. CONSTITUTION: A reaction type turbine apparatus includes a rotary shaft(110), at least one rotary part(120), and a chamber part. The rotary part includes a first body part(121), a second body part(122), and a nozzle. The first body part coupled to the rotary shaft is formed with a first material having a certain level of strength. The second body part coupled to one side of the first body part is formed with a second material different from the first material. The nozzle coupled to one side of the second body part is formed with a third material, and jets a working fluid outside. |
