This invention is developed to solve the problems described above. The object of this invention is to provide a vane adjustment mechanism to control the quantity of exhaust gas, which will have fewer components and a simpler design, which will operate in a stable fashion, and which will be extremely durable. The base unit comprises an inner base unit having first and second flanges, and an outer base unit 2B into which the inner base unit 2A is forced. A plurality of U-shaped indentations 2c spaced at regular angular intervals on the inside surface of the inner or outer base unit from the first flange 2a to the second flange 2b, so that the U-shaped indentations form the vane shaft holes to accommodate the vane lever units when the inner base unit is forced into the outer base unit to block the U-shaped indentations in such a way that the vane lever units are free to rotate. The link plate 3A has U-shaped cutting or concaved indentations, in which protrusions of the vane lever unit engage, all along the circumferential edge of the link plate 4.
