Abstract
Official abstract text for this publication.
A slide rail of a vehicle seat includes a first rail to which a screw having a screw thread formed on an outer periphery is fixed, and a second rail that retains a nut into which the screw screws, and moves relative to the first rail by the nut rotating. The first rail has a through-hole into which the screw is inserted. At least one end of the screw has a deformed portion that is deformed toward an outside in a radial direction of the screw with respect to the first rail while the at least one end of the screw is in a state passing through the through-hole, and that keeps the screw from slipping out of the through-hole.
First claim
Opening claim text (preview).
What is claimed is: 1. A slide rail of a vehicle seat, comprising: a first rail to which a screw, having a screw thread provided on an outer periphery of the screw, is fixed; and a second rail that retains a nut into which the screw screws, the second rail is configured to move relative to the first rail by the nut rotating, wherein the first rail has a bracket provided with a through-hole into which the screw is screwed, the through-hole having a first diameter portion and a second diameter portion and a diameter of the first diameter portion is greater than a diameter of the second diameter portion, at least one end of the screw has a deformed portion that is deformed toward an outside in a radial direction of the screw with respect to the first rail while the at least one end of the screw is in a state passing through the through-hole, the deformed portion has a diameter that is larger than the diameter of the second diameter portion of the through-hole so as to keep the screw from slipping out of the through-hole, and the second diameter portion has a thread provided on an inside surface of the second diameter portion. 2. The slide rail according to claim 1 , further comprising: a restricting portion that restricts an amount that the screw is inserted into the through-hole, the restricting portion is provided on at least one of the screw and the through-hole. 3. The slide rail according to claim 2 , wherein the restricting portion is defined by a step provided on at least one of the screw and an inside of the through-hole. 4. The slide rail according to claim 1 , wherein an incomplete thread is provided on one of the screw and the through-hole. 5. The slide rail according to claim 4 , wherein the incomplete thread is provided on a base end of the screw.
