Claims

[Scope of utility model registration request]

The compressor main body consisting of a compressor part and an electric motor part is housed inside, and it is constructed by joining an upper container and a lower container, and there is a straight line at approximately the center in the height direction to join the two containers. In a substantially spherical airtight container for a compressor forming a cylindrical portion, the lower container has a radius of curvature of a curved surface connected to the straight cylindrical portion of 50 mm.
In the following cases, the center point of the radius of curvature of the next curved surface connected to this curved surface is set to When the length _L1 is above the hypothetical lower end surface of the cylindrical part, and the horizontal distance from the straight cylindrical part to each center point is _L2 , tan ^-1 ( _L1 / _L2 )>6°. A closed container for a compressor, characterized in that the container is set at a position that satisfies a relational expression.
