## Abstract

A rotary machine includes: a rotary shaft supported by a bearing provided on a bearing base; and a casing housing the rotary shaft at least in part. The casing includes at least one support leg configured to support the casing on a base plate of a support structure member, and a support leg of the at least one support leg is supported on a support leg base provided on the base plate. The rotary machine further includes a height adjustment mechanism configured to adjust height of the casing, and the height adjustment mechanism includes an inclined surface of a support leg formed on the support leg, an inclined surface of a support leg base formed on the support leg base while facing the inclined surface of the support leg, and an actuator configured to move the support leg and the support leg base relative to each other.

## Claims
