Disclosed is a split type actuator housing which newly configures assembling and fastening structures of a plurality of actuator housings installed at a gearbox housing to absorb processing error occurring when fabricating a single housing and an assembling error occurring when assembling the single housing, in order to secure an accurate mounting position of the actuator housings at the gearbox housing. The actuator housing includes a pair of main housings (120, 220); a pair of sub-housings (140, 240) individually assembled to the main housings (120, 220), respectively; first mounting portions (122-142, 222-242) formed at portions facing each other between the pair of main housings (120, 220) and the pair of sub-housings (140, 240), respectively; second mounting portions (160, 260) formed to share a single reference axis line (X) for axial alignment with respect to the pair of main housings (120, 220); third mounting portions (180, 280) setting a coupling axis line (Y) to mutually assemble with respect to the pair of main housings (120, 220) to restrain relative motions toward the axial direction and the axial orbiting direction; and fourth mounting portions (144, 224, 244) formed at one or more portions among the pair of main housings (120, 220) and the pair of sub-housings (140, 240). |
