An angular indexing apparatus for a machine tool includes a housing, a rotating shaft, and a drive motor, the housing having a through hole, the rotating shaft (52) having a member that is rotationally driven secured to one end thereof, the rotating shaft being rotatably supported by a bearing in the through hole of the housing, the drive motor rotationally driving the rotating shaft to index an angular position thereof. The bearing is a roller bearing which has a plurality of rows and which is capable of supporting an axial-direction load and a radial-direction load. The rotating shaft is supported by two or more of the bearings disposed apart from each other in a direction of axis of rotation thereof. |
