Abstract
A separation structure of internal gear and housing includes an internal gear including a tubular body that has an inner circumferential surface and internal-gear teeth formed on the inner circumferential surface. The separation structure also includes a tubular housing configured to accommodate the internal gear. The tubular body includes a flange formed on an outer circumferential surface of the tubular body and projecting radially outward. The flange extends continuously and circumferentially along the tubular body, and the flange has a recess formed at an outer circumferential surface of the flange. A gap is formed between the outer circumferential surface of the tubular body of the internal gear and an inner circumferential surface of the housing. The housing has a projection. Contact between the recess of the flange and the projection of the housing restricts circumferential movement of the internal gear.
