A test apparatus for an actuator, the test apparatus comprising: a load part configured to output a load to be applied to an actuator to be tested, characterized in that the test apparatus further comprises a first lever part (51, 52) configured to swing in connection with the output from the load part, around a rotational shaft; a link part coupled to an output from the actuator to be tested; a second lever part coupled to the link part in a swingable manner, the second lever part configured to swing around a rotational shaft that is coaxially arranged with the rotational shaft around which the first lever part (51;52) is adapted to swing, and a power transmitting part configured to establish and undo a coupling between the first lever part (51, 52) and the second lever part, wherein the power transmitting part is configured to: establish said coupling between the first lever part (51, 52) and the second lever part to swing both the first lever part (51, 52) and the second lever part integrally with each other around the respective rotational shaft around which each is configured to swing, in connection with the output from the load part; and undo said coupling between the first lever part (51, 52) and the second lever part to swing only the first lever part (51, 52) among the first and second lever parts (51, 52, 53) around the rotational shaft, around which the first lever part (51;52) is adapted to swing, in connection with the output from the load part while the second lever part is configured to swing around the rotational shaft, around which the second lever part is adapted to swing, independent from the first lever part (51, 52). a load part configured to output a load to be applied to an actuator to be tested, characterized in that the test apparatus further comprises a first lever part (51, 52) configured to swing in connection with the output from the load part, around a rotational shaft; a link part coupled to an output from the actuator to be tested; a second lever part coupled to the link part in a swingable manner, the second lever part configured to swing around a rotational shaft that is coaxially arranged with the rotational shaft around which the first lever part (51;52) is adapted to swing, and a power transmitting part configured to establish and undo a coupling between the first lever part (51, 52) and the second lever part, wherein the power transmitting part is configured to: establish said coupling between the first lever part (51, 52) and the second lever part to swing both the first lever part (51, 52) and the second lever part integrally with each other around the respective rotational shaft around which each is configured to swing, in connection with the output from the load part; and undo said coupling between the first lever part (51, 52) and the second lever part to swing only the first lever part (51, 52) among the first and second lever parts (51, 52, 53) around the rotational shaft, around which the first lever part (51;52) is adapted to swing, in connection with the output from the load part while the second lever part is configured to swing around the rotational shaft, around which the second lever part is adapted to swing, independent from the first lever part (51, 52). establish said coupling between the first lever part (51, 52) and the second lever part to swing both the first lever part (51, 52) and the second lever part integrally with each other around the respective rotational shaft around which each is configured to swing, in connection with the output from the load part; and undo said coupling between the first lever part (51, 52) and the second lever part to swing only the first lever part (51, 52) among the first and second lever parts (51, 52, 53) around the rotational shaft, around which the first lever part (51;52) is adapted to swing, in connection with the output from the load part while the second lever part is configured to swing around the rotational shaft, around which the second lever part is adapted to swing, independent from the first lever part (51, 52).
