Abstract
An actuator is provided that is smaller in size and has a simpler structure, as compared with a conventional one. The actuator is composed of a driving mechanism that includes an electric motor, and a housing that houses the driving mechanism. The housing includes an air hole that communicates the inside of the housing with the outside thereof, a filter that covers the air hole, and a motor box that surrounds the electric motor. At least one of members of the motor box acts as a scattering prevention wall that prevents lubricant from scattering to the electric motor. The air hole is formed in a member of the motor box other than said at least one of members of the motor box.
