<p>[Problem] To provide an electric linear actuator having a reduced number of components, a reduced weight through a simplified structure, and a reduced cost through a shorter assembly time. [Solution] A deceleration mechanism (6) and a ball screw mechanism (8) are assembled to a bracket (2) and a cup-shaped cover (21) is detachably attached to the bracket (2). The cover (21) is formed by injection molding a thermoplastic synthetic resin, and has at an opening end part a latch (22) protruding in a radial direction. An annular groove (23) is formed in the bracket and the latch (22) of the cover (21) is caught in the annular groove (23). The cover (21) is attached in an elastically deformed state, and at least the ball screw mechanism (8) is hermetically sealed from the outside.</p> |
