Provided is a drive unit for a windmill that is configured such that even if excessive external forces act on one drive unit for a windmill when a plurality of drive units for a windmill are installed and used, possible breakage in the drive unit for a windmill can be prevented, and even in the case where a cutaway portion that serves as a mechanism for preventing breakage is provided, the operation of replacing the cutaway portion can be readily performed. A cutaway portion (19) is provided in a driving force transmission path and serves as a disconnection mechanism for disconnecting the driving force transmission path under the action of a torque of a predetermined magnitude or more, the driving force transmission path being a path through which a driving force is transmitted from an output shaft (14) to a pinion (13). A partitioning portion (20) is provided inside the body (11) and disposed between the cutaway portion (19) and a speed reduction portion (17) so as to partition an area between the cutaway portion (19) and the speed reduction portion (17). |
