In a linear actuator in which a slide table on a pedestal is caused to reciprocate linearly by two air cylinder mechanisms mounted in the pedestal, exhaust holes are provided to positions adjacent to ports, flow rate restricting mechanisms for restricting a flow rate of exhaust are provided between the exhaust holes and the ports, and pieces of cushion packing for being positioned over one of through holes of the ports on an exhaust side immediately before the piston reaches a stroke end is provided to an outer peripheral face of the piston to cause compressed air in pressure chambers to be discharged from the exhaust hole through the flow rate restricting mechanism.
