Abstract
A suspension device (S) comprises: an actuator (A) including a motion conversion mechanism (T) for converting rotational motion of a screw nut (1) to linear motion of a threaded shaft (2), and a motor (M) connected to the screw nut (1); and a fluid pressure damper (D) connected to the threaded shaft (2), wherein the threaded shaft (2) is formed in a cylindrical shape, a connecting shaft (30) for connecting a rod (31) or a cylinder (32) of the fluid pressure damper (D) to the threaded shaft (2) is inserted into the threaded shaft (2), and the connecting shaft (30) is connected to an end, opposite to the fluid pressure damper, of the threaded shaft (2). Accordingly, the connection between the actuator and the hydraulic damper is facilitated.
