A linear actuator comprises a motor, a rotation-to-linear motion conversion mechanism having a screw and a nut, a support block supporting an end of the screw, and an actuator-side support member with a swing support mechanism (e.g., a swing axis or bearing portion in case of a Trunnion mechanism, or a swing support bearing portion or support leg of the swing support bearing portion). The actuator-side support member is part of the support block or an extension member of the support block or connected therewith. The swing axis of the swing support mechanism is located in the plane including the screw axis, and the force flow line inside the linear actuator is limited on the output shaft, the nut, the screw and the support block.
