<p>An eccentric reduction gear which can enhance output torque without increasing the overall dimensions of a case in the radial direction. First to third coupling members (19, 20, 21) are arranged on a column (18) and couple a proximal carrier (16) with a distal carrier (17). In the column (18), one side extension (35) and the other side extension (36) are formed integrally at positions stretching farther to the rotation supporting hole (31) side than the tangents (R, S) touching the circumferential edge of the rotation supporting hole (31) while passing the center of the case (14) on one and the other sides of the case (14) in the circumferential direction on the radial outside thereof. A portion of the first coupling member (19) is located at the one side extension (35) and a portion of the second coupling member (20) is located at the other side extension (36). A portion of the third coupling member (21) is located at the overlapping position with the first coupling member (19) and the second coupling member (20) in the circumferential direction of the case (14).</p> |
