PROBLEM TO BE SOLVED: To provide a linear actuator, securing a fixed moving stroke area S1 (S) in a rotor 3 even in the case of a structure in which a projection area is not entirely secured or enough secured on the outside of the actuator on the output shaft 4 rear side, for example, the rear end side of the output shaft 4 by sealed by a partition 53 while the output shaft 4 is composed of a threaded shaft part 41 and a whirl-stop shaft part 42. SOLUTION: In the shaft hole 31, a screw carving part 311 formed in one side area and engaged with the screw carving part 41 and a guide part 313 for guiding a whirl-stop shaft part 42 formed in the other side area at a predetermined intermediate area 312 in the state of regulating the rotation are respectively provided in the divided areas to move forward and backward the whirl-stop shaft part 42 in a moving stroke area in the shaft hole 31.
