Abstract:
A drive device 1 comprises a first housing 2, a second housing 3 that moves relative to the first housing 2, a drive unit 4, a spindle member 5, a nut member 6, a mobile member 7, a coil spring 8, and a spring guide member 9. The first housing 2 has an inner circumferential face 21, an accommodation part 22 that accommodates the drive unit 4, and a projection 23 that projects from the inner circumferential face 21 toward the center. The spring guide member 9 has a spring support part 91 and a flange 92 that projects to the outside in the radial direction of the spring support part 91. The flange 92 of the spring guide member 9 is sandwiched between the projection 23 and the drive unit 4 in the axial X direction of the spindle member 5. By using such a structure, the drive device can be maintained in a compact form in the radial direction and the spring guide member can be fixed using a simple structure.
