  "textContent": "Construction of a suspension device 1 is achieved that allows for easy assembly, and by which the contractible amount of a coil spring thereof can be easily maintained. [0002] A bearing unit 5 is arranged between a part on the other side in the axial direction of a ball screw shaft 4 and an upper shell 2, and by a side surface on one side in the axial direction of a pressing plate 35 of the bearing unit 5 that is prevented from rotating with respect to the upper shell 2 coming in contact with a side surface on the other side in the axial direction of a flange section 9 of the upper shell 2 through a stopper holder 50, the bearing unit 5 rotatably supports the ball screw shaft 4 with respect to the upper shell 2. The circumscribed circle diameter of a ball nut 6 and inner tube 61 is less that the inner diameter dimension of the flange section 9. In other words, during assembly of the suspension device 1, an intermediate assembly 124 that includes the ball nut 6 and inner tube 61 can pass through the inner side in the radial direction of the flange section 9 of the upper shell 2.",
