PROBLEM TO BE SOLVED: To omit by preventing breakage of a connector unit, a confirmation work of the connector unit by visual observation or the like and then improve work efficiency.SOLUTION: In a gear case 31, which is equipped with a connector unit 50, is arranged a connector supporting portion 35a comprising a bottom wall portion 35b for supporting the opposite side of a side connected to an external connector of a connector connection portion 52 or a bottom wall portion 52a. This allows the connector supporting portion 35a of the gear case 31 to receive load transferred from the external connector when the external connector is connected to the connector connection portion 52 so that load on the connector connection 52 can be reduced to surely prevent breakage of the connector unit 50. This allows confirmation work of the connector unit 50 by visual observation or the like to be omitted, thereby improving work efficiency. |
