Provided is an angle indexing device for a machine tool, which comprises a housing having a through hole, a rotary shaft having a rotating object member fixed at one end and borne rotatably in the through hole of the housing by a bearing, and a drive motor for driving the rotary shaft rotationally thereby to index the angular position of the rotary shaft. The angle indexing device is characterized in that the bearing is a double-row type roller bearing for bearing loads in an axial direction and in a radial direction, and in that the rotary shaft is supported by two or more of the bearings arranged at a spacing in the rotating axial direction. |
