Abstract
A variable capacity vane pump () has a pump housing () having a high-load bearing part () on which a higher load is exerted than another part when the pump vane pump () operates. A control valve () for varying a capacity of the vane pump () is provided in a valve housing () which is formed integrally in the pump housing (). By arranging the valve housing () on the same side of the pump housing () as the high-load bearing part () with respect to the rotation axis of the vane pump (), the high-load bearing part () can be reinforced without increasing the size of the vane pump ().
