## Abstract

A sliding device of the present disclosure includes: a fixed rail; a movable rail; a rack fixed within the fixed rail, the rack extending along an axis parallel to a longitudinal axis of the fixed rail; a pinion provided to the movable rail, the pinion including multiple teeth to be engaged with the rack and rotating by receiving a driving force; and a restrictor slidingly displaced integrally with the movable rail, the restrictor contacting with the rack when the movable rail is sliding, to thereby restrict the rack from being displaced in a direction away from the pinion.

## Claims

### Claim 1

A sliding device that supports a vehicle seat in a slidable manner, the device comprising:
a fixed rail fixed to a vehicle;
a movable rail to which the vehicle seat is fixed, the movable rail being slidable relative to the fixed rail;
a rack fixed within the fixed rail, the rack extending along an axis parallel to a longitudinal axis of the fixed rail;
a pinion provided to the movable rail, the pinion comprising multiple teeth to be engaged with the rack and rotating by receiving a driving force; and
a restrictor slidingly displaced integrally with the movable rail, the restrictor contacting with the rack when the movable rail is sliding, to thereby restrict the rack from being displaced in a direction away from the pinion.

### Claim 2 (depends on 1)

The sliding device according to claim 1,
wherein a rotation center of the pinion is positioned upper than the rack, and
wherein the restrictor comprises a first sliding-contact portion that is slidingly contactable with at least part of a lower surface of the rack.

### Claim 3 (depends on 2)

The sliding device according to claim 2,
wherein, assuming that a horizontal axis substantially perpendicular to a longitudinal axis of the rack is a width axis, the first sliding-contact portion is slidingly contactable with the rack over an entire range along the width axis.

### Claim 4 (depends on 3)

The sliding device according to claim 3,
wherein the restrictor comprises:
a second sliding-contact portion that is slidingly contactable with one width-axis end side of the rack; and
a third sliding-contact portion that is slidingly contactable with another width-axis end side of the rack.

### Claim 5 (depends on 1)

The sliding device according to claim 1, the device further comprising a support member that is fixed to the movable rail and supports the pinion,
wherein the restrictor is provided to the support member.

### Claim 6 (depends on 1)

The sliding device according to claim 1,
wherein the rack is a strip-plate-shaped member containing multiple holes into which the multiple teeth of the pinion are insertable.
