Abstract
A linear actuator in which the number of limit switches to be mounted, as well as the mounting position and direction of limit switches, can be selected with a high degree of freedom, the limit switch mounting spacing can be made short, and a positive operation is ensured while using a small number of components. Flat limit switch mounting flanges are fixed onto an outer cylinder of a linear actuator so that their positions are adjustable in both axial and circumferential directions of the outer cylinder, and a guide rail for slidably guiding a striker is supported by and between the limit switch mounting flanges. The striker is connected with the actuator rod of the actuator by a connecting rod. With projection or retraction of the actuating rod, the striker moves and actuates limit switches attached to the associated limit switch mounting flanges.
