摘要： [PROBLEMS] An angular indexing device for a machine tool, in which large torque can be obtained on a rotating shaft without an increase in the outer diameter of a component incorporating a motor and which can be produced easily and at low cost. [MEANS FOR SOLVING PROBLEMS] The angular indexing device for a machine tool has a rotating shaft (40) to which a member (11) to be rotated is fixed, a housing (30) surrounding the outer periphery of the rotating shaft (40) and attached to and detached from a machine tool body, bearings (B1, B2) placed between the housing (30) and the rotating shaft (40), and drive means placed between the housing (30) and the rotating shaft (40) and rotating the rotating shaft (40) to index angular positions. Drive motors (M1, M2, M3) are used as the drive means, and the motors (M1, M2, M3) have motor rotors and motor stators arranged in the housing (30) so as to be concentric with the rotating shaft (40). The drive motors (M1, M2, M3) are serially arranged so as to be spaced in the direction of the axis of the rotating shaft (40), and at least either of the housing (30) and the rotating shaft (40) is connected so that it can be split into multiple sections in the direction of the axis of the rotating shaft (40). The housing (30) and the rotating shaft (40) are splitably connected to the corresponding drive motors (M1, M2, M3).
