Abstract: In a linear actuator, a slide table is attached to a cylinder body via a guide mechanism so as to be movable along the longitudinal direction of the cylinder body. The slide table includes a table body arranged above the cylinder body and extending in the longitudinal direction, and an end plate joined to an end of the table body in the longitudinal direction so as to be substantially orthogonal to the table body. The end plate includes a storage chamber provided on one surface thereof in the longitudinal direction facing a guide mechanism and depressed from the one surface in a direction away from the guide mechanism. For example, when the linear actuator is used in an environment where powder dust and the like is scattered, the storage chamber stores therein a solidified matter made up of the powder dust and the like.
