ABSTRACT:
A linear actuator includes a base having a positioning post and a motor fixed on one side of the base. A spindle positioning means includes a spindle, a seat and a fixing element. The spindle protrudes from the motor and penetrates the base. One side of the spindle away from the motor is formed with a free end. The seat includes a cylinder and an extension plate protruding outwards from the periphery of the cylinder. The extension plate is provided with a trough. The cylinder is connected to the free end of the spindle. The trough of the extension plate is located to correspond to the positioning post. The fixing element passes through the trough to fix the seat on the positioning post. Via this arrangement, the breakage of the spindle caused by a lateral force can be prevented efficiently.
