PROBLEM TO BE SOLVED: To provide a casing structure of a direct-acting drive device 1, assembly work of which the is simplified by performing connection work of a wiring board 92 or a connector 91 to a connection pin 11b in a preceding step of accommodating a gear case 3 in an outer case 2 by clearing the conventional need to provide a stepwise protruding ring-shaped receiver supported and received by a metal die of a caulking machine around an outer circumference of the casing or to use a rubber sheet which is interposed in caulking and crimping.SOLUTION: In a cylindrical gear case 3, a gear accommodation part 31 and a motor accommodation part 32 are formed for accommodating reduction gear means 12 and a motor 11, respectively. On an arcuate surface of the gear case 3, a communicating recessed groove for disposing a power feeding member is formed from a recessed groove portion 311 formed in the gear accommodation part 31 and a groove part 61 which is formed at a side of the motor accommodation part 32 while interposing a recessed bush 6, in such a manner that an inflow path for inflow of a liquid-state sealant 7 is formed when an outer case 2 is fitted. |
