PROBLEM TO BE SOLVED: To provide an electric linear actuator which achieves downsizing and makes a rod less likely to buckle.SOLUTION: A ball screw mechanism 3 includes: a nut 7 where a thread groove is formed on an inner peripheral surface; and a rod 8 which is inserted into the nut 7 through multiple balls disposed between the rod 8 and the thread groove of the nut 7 and has a thread groove on an outer peripheral surface. In the nut 7, an outer peripheral surface is fixed to an inner peripheral surface of a motor shaft 4 in an area ranging from one axial end part to the other axial end part. |
