ABSTRACT:
A suspension device (A) comprising a damper (S) and a gas spring (C), the damper (S) comprising a motion transforming mechanism (H) for transforming a relative motion between a vehicle body-side member and an axle-side member into a rotational motion and a motor (M) having a rotor (8) to which the rotational motion is transmitted, the gas spring (C) being interposed between the vehicle body-side member and the axle-side member, in which the motor (M) comprises a hollow casing (9), a partition wall member (16) which forms a rotor chamber (r) within the casing (9), with the rotor (8) being received within the rotor chamber (r), a cylindrical stator (17) disposed between an outer periphery of the partition wall member (16) and an inner periphery of the casing (9), and the rotor (8) held rotatably by the casing (9) within the rotor chamber (r), and the interior of the rotor chamber (6) is brought into communication with the interior of a gas chamber (R) of the gas spring (C). According to this construction, it is possible to avoid an increase in size of a suspension device utilizing a motor and with a gas spring applied thereto.
