Abstract
A scroll structure of a rotary machine and a rotary machine is provided in which it is possible to achieve an improvement in reliability and functionality of a rotary machine such as a turbine and to achieve a reduction in size. Provided are a scroll main body that entirely covers an area surrounding an annular channel extending in a circular shape about a rotational axis in a rotating portion of a rotary machine and a cylindrical channel extending from the annular channel at the rotational axis side and extending towards the rotating portion; and a fitting portion that supports the scroll main body with respect to a support portion and a casing accommodating the scroll main body so as to enable expansion and contraction in a radial direction centered on the rotational axis, while restraining the scroll main body in the direction along the axial axis.
