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.

An end of a conductor having a stranded conductor layer wound around a tension member made of resin-reinforced carbon fiber is cut back to expose the end of the tension member. The exposed end of the tension member is inserted into a metal fitting having multiple longitudinal slits. A metal sleeve is then fit over the metal fitting and also partially over the stranded conductor layer before compress-fitted into place. Accordingly, it is possible to attach, with good workability and sufficient tensile strength, a conductor that has a tension member made of resin-reinforced carbon fiber.
