FIELD : machine building. SUBSTANCE : invention relates to machine building and can be used in drives of the hospital beds. The linear actuator comprising casing (1) out of at least two parts (1a, 1b), mounting frame (2), reverse motor (7) with mechanical gear (22), spindle (5) driven by the reverse motor (7) via the gear, enclosure (16) for the spindle (5) installation, spindle nut (6) installed without possibility of rotation on the spindle (5), outside pipe (3) installed such that the spindle (5) passes inside it, actuator (4) installed telescopically inside the outside pipe (3) and connected with the spindle nut (6), front connection (8) on the outside end of the actuator (4), rare connection (9) inside the casing (1). The rare connection (9) has slot (31) for the spindle (5) bearing, at that the reverse motor (7), gear (22) and outside pipe (3) are secured on the mounting frame (2), at that the mounting frame (2) is made as separate element that is load-carrying structure of the actuator. The mounting frame (2) has wall (2a), around which and on which two parts (1a, 1b) of casing (1), reverse motor (7), gear (22) and outside pipe (3) of actuator are installed, the outside contour of the wall (2a) of the mounting frame (2) complies or mainly complies with the outside contour of the casing (1) cross-section. EFFECT : high technical characteristics are achieved. 10 cl, 8 dwg
