PROBLEM TO BE SOLVED: To provide an electric linear actuator capable of appropriately holding an output shaft and an output shaft vibration electric drive device having the electric linear actuator.SOLUTION: An electric linear actuator 40 includes: a fixed block 50; an output moving block 60; a moving pair block 70; a protruding side coupling part 80; a pull-in side coupling part 90; a block coupling part 100; an output function part 200 and a coupling function part 300. The output function part 200 includes: an output part main body 210; an output shaft coupling part 220; and an output part reinforcement 230, and has a structure in which the output part main body 210 and the output shaft coupling part 220 are coupled with each other. The output part main body 210 is coupled with the output moving block 60. The output shaft coupling part 220 is coupled with the output shaft 20. The output part reinforcement 230 has a structure to reinforce the output part main body 210 and the output shaft coupling part 220. |
