Mounting structure, rotational machinery, and air conditioning apparatus

Abstract

According to one embodiment, a mounting structure includes a first member, a second member and a support. The first member includes a first outer surface extending along and around a first axis. The second member has a first surface to which a first hole opens, the first hole extending along the first axis to house the first member. The support is rotatable integrally with the first member around the first axis and has a second surface facing the first surface. One of the first surface and the second surface is provided with first dents. The other of the first surface and the second surface is provided with at least one first bump that fits into at least one of the first dents to limit a relative rotation between the second member and the support around the first axis.
