PROBLEM TO BE SOLVED: To provide a swinging support method by an effective trunnion or a crevice such as the screw bending directional moment is not applaied to a rotation/straight line converting mechanism part for supporting thrust in a freely swinging support point arranging system of a motor-driven linear actuator of a system for converting rotation of a screw into linear motion of an output shaft. SOLUTION: A linear actuator side constitutive element (for example, a swinging shaft in a trunnion, and a swinging shaft receiving/holding leg in a crevice) of a swinging support mechanism is integrally provided in or connected/fixed to a support block for supporting a screw in the shaft direction or an expansion member of the support block, and the swinging shaft is made to exist in the same plane as the axis of the screw. |
