Rotary machine

A rotary machine comprising:

• a base plate;
• a bearing base provided on the base plate;
• a rotary shaft supported by a bearing provided on the bearing base;
• a casing housing the rotary shaft at least in part;
• at least one support leg supporting the casing and including an inclined surface;
• a support leg base provided on the base plate, supporting a support leg of the at least one support leg, and including an inclined surface formed while facing the inclined surface of the support leg;
• and
• a height adjustment mechanism provided on the base plate and configured to adjust height of the casing,
• wherein the height adjustment mechanism includes a drive mechanism configured to move the support leg and the support leg base relative to each other along a contact surface between the inclined surface of a support leg and the inclined surface of a support leg base,
• wherein an inclined surface of the support leg and an inclined surface of the support leg base each include a first inclined surface having a first inclination angle and a second inclined surface having a second inclination angle,
• wherein the first inclined surface and the second inclined surface of one of the support leg and the support leg base are disposed while forming a V-shaped groove in combination,
• the first inclined surface and the second inclined surface of the other of the support leg and the support leg base are disposed while forming a wedge shape complementary to the V-shaped groove,
• wherein the first inclined surface and the second inclined surface of the support leg are continuously provided on the same inclined surface of the support leg, and
• wherein the first inclined surface and the second inclined surface of the support leg base are continuously provided on the same inclined surface of the support leg base.
