PROBLEM TO BE SOLVED: To enhance the accuracy in assembly of a linear actuator, and also to enable the evaluation of the rotation properties of a rotor, in the condition where there is no output shaft. SOLUTION: An end plate 90 on the side of the rear end 60b of a stator assembly 60 and a tip part 100 on the side of the tip 60a of the stator assembly 60 are formed simultaneously, by injection molding 68 for unifying the stator assembly 60. Hereby, the centers of the end plate 90 and the front part 100 can be coincided accurately with the center of the stator assembly 60, whereby the accuracy in assembly of a motor is increased. Moreover, ball bearings 101 can be attached to the front part 100, rather than via an output shaft 80, and in this condition, where the rotation properties of the rotor 70 can be evaluated.
