PROBLEM TO BE SOLVED: To reduce noise of a spindle drive for electrically adjusting an adjustment component.SOLUTION: A spindle drive includes a tubular spindle drive case provided with a driving unit downstream connected to a spindle-spindle nut gear and generating linear driving, inside thereof, and a connecting portion 1 inserted to one end of the spindle drive case. The connecting portion is projected to an outer side through a damping unit 4 made of an elastic material, and connected to a joint 11. The connecting portion includes a first flange-shaped end portion 2 and a second flange-shaped end portion 3, front sides 5, 6 opposite to each other, of the first and second flange-shaped end portions are opposed to each other with a clearance, and the damping unit is disposed in the clearance. A front surface side 5 of the first flange-shaped end portion by one front surface 8 of the damping unit, and a front surface side 6 of the second flange-shaped end portion by the other front surface 9 of the damping unit are connected by vulcanization treatment or adhesion, and the second flange-shaped end portion includes a joint at a side opposite to the damping unit, of the second flange-shaped end portion.SELECTED DRAWING: Figure 1 |
