PURPOSE:To aim at ease of car hight selection and reduction in operating force, by installing a togle linkage mechanism between the arm clamped to one side torsional end of a torsion bar and a car body, and making this toggle linkage, mechanism so as to be actuated to both level up and down positions with an actuator. CONSTITUTION:A lock nut 34 is loosened to some extent, a bar part 30 of a link 21 is oppositely rotated to a cylindrical part 26 around a sahft, having a position of an adjusting member 33 varied to the axial direction, and an angle of an arm 13 is varied whereby a car hight is selected. And, when downward force works on a shaft 23 of a toggle linkage mechanism 20 by body load to be added to a lower lind 12 in an F direction, a rod 43 of an actuator 40 is extended, coming into contact with an extension side end 42a, thus an ordinary level is secured. On the other hand, at the time of level down, hydraulic pressure is fed out of an oil port 46, retracting the rod 43. At the time of level up, this hydraulic pressure is exahusted. With this constitution, level selection is made so easy and operating force reduction is well promoted. |
