PROBLEM TO BE SOLVED: To provide an electrically driven actuator for surely preventing the entry of water to the side of a rotation driving source.SOLUTION: In a housing 22 constituting an electrically driven actuator 10, a storage part 28 is formed to store a rotation driving source 24. Between a first mounting face 34 via which the housing 22 is mounted on an adaptor 26 and the storage part 28, a first recessed part 44 is formed. The first recessed part 44 is formed to be gradually wider toward the lower side in the gravity direction of the electrically driven actuator 10. Water entering from the lower side through a clearance 70 between the housing 22 and the adaptor 26 is reserved therein to prevent the entry of water from a breathing hole 46 communicated with the first recessed part 44 to the side of the storage part 28. |
