A magnetic resonance apparatus gantry includes a cylindrical static magnet housing which accommodates a static field magnet and in which an opening portion is formed, a cylindrical gradient magnet housing which accommodates a gradient coil, is placed in the opening portion, and is shorter in length in an axial direction than the static magnet housing, and a support unit which supports the gradient magnet housing on the static magnet housing, and includes a first support member mounted on the static magnet housing, a second support member mounted on the gradient magnet housing and supported by the first support member, and an adjustment unit which is placed inside the static magnet housing in the axial direction and adjusts a relative positional relationship between the static magnet housing and the gradient magnet housing by changing the relative positional relationship between the first support member and the second support member.
