PROBLEM TO BE SOLVED: To provide an inexpensive but still a long life reduction gear. SOLUTION: Because relative rotary support of an output member 27 and a stationary case 25 is performed by an angular ball bearing 30 provided between the stationary case 25 and the output member 27, load is supported by rolling contact, which results in practically no wear and thereby life of a reduction gear can be prolonged. In addition, the reduction gear can be made inexpensively because such angular ball bearing 30 is inexpensive as compared with cross roller or taper roller bearings. |
