PROBLEM TO BE SOLVED: To prevent a feed screw from rubbing strongly with a support in the radial direction even when the feed screw causes axis deviation during rotary drive.SOLUTION: A feed screw support for vehicular seats supports a feed screw 21 in an axially rotatable way and includes a bearing implement 21A supporting the front end part 211 of the feed screw 21 and an end cap 21B supporting the rear end part 212 of the feed screw 21. The bearing implement 21A supports the front ende part 211 of the feed screw 21 in an axially rotatable way. The end cap 21B supports the rear end part 212 of the feed screw 21 in an axially rotatable way by bringing a convex spherical surface 212A formed in the rear end part 212 of the feed screw 21 and protruding in the axial direction into point contact with a concave spherical surface 21B1 formed in the end cap 21B and dented in the axial direction. |
