An eccentric speed reducer is provided with which it is possible to achieve improved output torque without increasing the outer radial dimension of the casing. A tapered side is formed on at least part of a peripheral side surface of struts 18, with the tapered side extending in a tapered manner in the longitudinal direction of the struts 18 in a direction that is oblique to a direction parallel to a center line P passing through a casing 14 so as to connect inner circumferential centers of the casing 14 and in which the struts 18 narrow toward an end carrier 17. A tapered side gradient that is the angle of a direction in which the tapered side extends relative to the direction parallel to the center line P is formed to be at least 3 degrees and at most 6 degrees.
