LINEAR MOTOR ACTUATOR AND MULTI-AXIS LINEAR MOTOR ACTUATOR

PROBLEM TO BE SOLVED: To provide a linear motor actuator which enables a shaft member to be selected independently of a rod for housing multiple magnets and also enables an entire length to be shortened without decreasing a thrust force.SOLUTION: A second shaft member 12 is arranged in parallel with a rod 1 of a linear motor. A tip of the rod 1 is connected with a tip of a second shaft member 12 by a first connection member 11 so that the second shaft member 12 linearly moves in conjunction with the linear movement of the rod 1. A second connection member 14 prevents the second shaft member 12 from revolving around an axis line of the rod 1. The second shaft member 12 is rotated by a motor.
