Abstract
A locking mechanism of a linear motor travel slider, includes: a serration member having a teeth portion and disposed on one of the bed and the travel slider extending in a slider-traveling-direction; a bracket supported by the other of the bed and the travel slider; an actuator supported by the other of the bed and the travel slider; a locking member supported by the actuator having a teeth portion engageable with the teeth portion of the serration member; and a controller for controlling the actuator to retain the lock member in an unlocked position when the linear motor is energized and for stopping the actuator when the linear motor is in a stop state due to a power failure. The locking member includes an urging member for making the locking member engage with the serration member while the actuator is in a stop state.
