Abstract
There is provided an eccentric speed reducer that achieves improved output torque without increasing the outer radial dimension of a casing. The strut includes, at the basal portion of a peripheral side surface where the strut is continuous with the base carrier, first curved portions and second curved portions that are in a form of a curved surface having a different radius of curvature. The first curved portions are provided at the supporting hole-facing sides of the strut that are disposed facing the rotation supporting holes. The second curved portions are provided between an outer side located in the strut at an outer position in the radial direction of the casing and on the side facing the inner circumference of the casing, and supporting hole-facing sides. The second curved portions have a larger radius of curvature than the first curved portions.
