PURPOSE:To aim at improvement in system reliability, by installing the countershaft connected to each power module, in a second step reduction mechanism of a speed reducer, and driving accessories via a one-way clutch. CONSTITUTION:The countershaft connected to each power module is installed in a second step reduction mechanism of a speed reducer. An intermediate gear 43a is pivotally supported on the countershaft 42 via a one-way clutch 48. An accessory driving gear 50 is clamped to this intermediate gear 43a. With this, an accessory driving mechanism related to these power modules being stopped can be driven by power out of other power modules being operated, so that reliability in the whole device is improvable.
