摘要：
A base member is structured to define a portion of a casing in which a gas with a density lower than that of air is to be sealed and to support a motor to be housed in the casing. The base member includes a base body made of a cast material, an information mark, and an insulating coating layer. The information mark includes casting information and is located on a portion of a surface of the base body. The insulating coating layer is defined on the surface of the base body and covers the information mark.
