Abstract
A rotating electric machine case includes: a body in a hollow shape; and a flow path, provided between an inner circumferential portion and an outer circumferential portion of the body, configured to allow a refrigerant to pass from one end portion toward the other end portion in an axial direction of the body. In addition, an inner diameter of the body is constant in the axial direction of the body, and a dimension from the inner circumferential portion of the body to the outer circumferential portion of the body is larger on a downstream side of the flow path than on an upstream side of the flow path.

A rotating electric machine case, comprising:
- a body in a hollow shape;
- and
- a flow path, provided between an inner circumferential portion and an outer circumferential portion of the body, configured to allow a refrigerant to pass from one end portion toward the other end portion in an axial direction of the body,
- wherein an inner diameter of the body is constant in the axial direction of the body, and a dimension from the inner circumferential portion of the body to the outer circumferential portion of the body is larger on a downstream side of the flow path than on an upstream side of the flow path, and
- wherein a dimension from a part of the flow path facing the outer circumferential portion of the body to the outer circumferential portion of the body is larger on the downstream side of the flow path than on the upstream side of the flow path.
