Abstract

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; a second rail that retains a nut into which the screw screws, and moves relative to the first rail by the nut rotating; a protruding portion that is provided on the first rail, and protrudes toward the screw; and an elastic member that connects the protruding portion and the screw. The elastic member has a retaining body that retains the screw, and an engaging body that engages with the protruding portion.

First claim

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;
a second rail that retains a nut into which the screw screws, the second rail being configured to move relative to the first rail by the nut rotating;
a protruding portion that is provided on the first rail and protrudes toward the screw; and
an elastic member that connects the protruding portion and the screw, wherein
the elastic member has a retaining body that retains the screw and an engaging body that engages with the protruding portion, and
the protruding portion is provided with a through-hole and only the engaging body passes through the through-hole so as to engage with the protruding portion.

2. The slide rail according to claim 1 , wherein
the protruding portion has a L shape that includes a bottom piece and a rising piece that includes the through-hole;
a protrusion protrudes from the engaging body of the elastic member; and
the elastic member is assembled to the protruding portion by the protrusion being inserted into the through-hole in the rising piece of the protruding portion.

3. The slide rail according to claim 2 , wherein
when the elastic member is assembled to the protruding portion, the retaining body of the elastic member is supported by an upper edge of the rising piece of the protruding portion.

4. The slide rail according to claim 2 , wherein
when the elastic member is assembled to the protruding portion, the retaining body of the elastic member protrudes from the rising piece of the protruding portion toward a side opposite a side where the elastic member is assembled to the rising piece.

5. The slide rail according to claim 1 , wherein
the retaining body and the engaging body are vertically aligned.

6. The slide rail according to claim 1 , wherein
the retaining body is provided adjacent to a face defining an outer periphery of the protruding portion.

7. The slide rail according to claim 6 , wherein
the retaining body is supported by a recessed portion provided on the outer periphery of the protruding portion.

8. The slide rail according to claim 1 , wherein
the engaging body includes a protrusion provided in the through-hole of the protruding portion,
the retaining body includes a through-hole that receives the screw therein, and
a portion of the protruding portion is disposed between the protrusion of the engaging body and the through-hole of the retaining body.
