PROBLEM TO BE SOLVED: To miniaturize a linear motor unit while maintaining a thrust of a linear motor.SOLUTION: A linear motor unit 60 is provided with a plurality of linear motors 70 each having a stator 72 fixed to a mounting frame 61 by fastening a stationary bolt B with a core 75 around which a coil 76 is wound; and a movable element 73 moving forward and backward by controlling energization of the coil 76. Cores 75 and mounting parts 90 provided to the mounting frame 61 are alternately arranged in a fastening direction of the stationary bolt B. A shaft center Q of the stationary bolt B fixing one of the adjacent cores 75 is displaced from a shaft center Q of the stationary bolt B fixing the other of the adjacent cores 75, and therefore, a shaft part B2 of the stationary bolt B fixing one of the cores and a shaft part B2 of the stationary bolt B fixing the other are aligned in a displacement direction of the stationary bolts B. |
