    • In a rear wheel toe angle control system, the toe angle response properties of the right and left wheels are prevented from differing from each other depending on the operating condition of the vehicle, and the handling of the vehicle can be improved. The rear wheel toe angle control system (10) comprises a control command angle computing unit (83) for setting a target toe angel for each rear wheel (5) according to an operating condition of the vehicle (V), an angle-length conversion unit (87) for setting a target operating amount of each electric actuator (11) according to the target toe angle, a stroke sensor (17) for detecting an actual operating amount of each electric actuator (11), a motor position feed back duty computation unit (89) for setting a control value of each electric actuator (11) according to the difference between the actual operating amount and the target operating amount, and a compensating unit (90) for compensating the control value according to a value such as the lateral acceleration of the vehicle body (1) which is associated with the axial force of each electric actuator (11).

    • A precision moving mechanism can rotate a table continuously and precisely. A first drive disk is made of first and second movable sections and a resilient hinge connecting these sections. A first piezoelectric element has ends coupled to these sections, which can be attached to a first base by first and second members. A second drive disk is made of third and fourth movable sections and a resilient hinge connecting these sections. A second piezoelectric element has ends coupled to these sections, which can be attached to the second base by third and fourth members. The second and third sections are coupled to the second base and table, respectively. During the first period, the first member attaches the first section to the first base, the fourth member attaches the fourth section to the second base, and the first element expands, and the second element contracts, whereby the second section slightly rotates to rotate the table. During the second period, the second member 46 attaches the second section to the first base, the third member attaches the third section to the second base, the first element contracts and the second element expands, whereby the fourth section slightly rotates to rotate the table.
