Abstract

An electric power steering device () according to the present invention includes: a gearbox; and a driving control unit () connected to the gearbox through a mounting-portion contact surface (). The driving control unit () includes an outer-diameter gradually increasing surface () formed on one end portion thereof, the outer-diameter gradually increasing surface () being connected so that an outer diameter thereof on the mounting-portion contact surface () matches with an outer diameter of the gearbox. Thus, it is possible to prevent a liquid from entering inside through the mounting-portion contact surface (), thereby preventing electrical insulating properties of internal electric components from being lowered.
