The present invention relates to a vane cartridge device for a variable geometry turbocharger. According to the present invention, a trailing corner is positioned in the lower portion of a shaft portion in a vane, and cylindrical portions are formed in upper and lower portions of the trailing corner so that no gap is generated in a trailing edge part, and flow disturbance can be prevented. The present invention includes a control ring that has a ring shape and has multiple vane arm grooves at regular intervals along an inner circumferential surface; multiple vane arms that are mounted on the respective vane arm grooves; multiple vanes that are connected to the respective vane arms; a vane base ring that is connected to the control ring by a support pin and forms a flow channel with the control ring; and a vane cover ring where the vane is rotatably mounted. |
