The attachment portion is attached to the upper rail such that the light emitter is arranged outside the slide rail. According to the slide device, since the attachment portion is attached to the upper rail such that the light emitter is positioned outside the slide rail, the light emitter does not move inside the slide rail to which a large amount of grease is applied, and a decrease in communication performance can be prevented. ## Claims ### Claim 1 A slide device, comprising: an upper rail to which a slide seat for a vehicle is attached; a slide rail to which the upper rail is slidably attached; a light emitter; and an attachment portion that attaches the light emitter to the upper rail, wherein the attachment portion is attached to the upper rail such that the light emitter is arranged outside the slide rail. ### Claim 2 (depends on 1) The slide device according to claim 1, wherein the slide rail includes a pair of inner walls vertically provided inside the slide rail, and wherein the attachment portion is attached to the upper rail such that the light emitter is arranged between the pair of inner walls. ### Claim 3 (depends on 1) The slide device according to claim 1, wherein the slide rail includes: a bottom wall that is mounted on a floor, a pair of side walls that are vertically arranged from both sides of the bottom wall extending in an orthogonal direction orthogonal to a sliding direction on the bottom wall in which the upper rail moves along the slide rail, a pair of upper walls that extend to approach each other from upper ends of the pair of side walls in an erecting direction in which the pair of side walls are vertically arranged, and a pair of inner walls that extend downward for the floor from end portions of the pair of upper walls, the end portions of the pair of upper walls being separated from the upper ends of the pair of side walls in a direction in which the pair of upper walls extend, and wherein the attachment portion is attached to the upper rail such that the light emitter is arranged between the pair of inner walls. ### Claim 4 (depends on 1) The slide device according to claim 1, further comprising: a cover member that is arranged over the slide rail, wherein the attachment portion is attached to the upper rail such that the light emitter is arranged between the slide rail and the cover member. ### Claim 5 (depends on 1) The slide device according to claim 1, further comprising: a cover member that is arranged over the slide rail, wherein the slide rail includes a slit, and the cover member covers the slit of the slide rail, wherein the upper rail includes: a slide portion that is arranged inside the slide rail, and a seat attachment portion that protrudes from inside the slide rail to outside the slide rail through the slit of the slide rail, and to which the slide seat for the vehicle is attached, wherein the seat attachment portion protrudes from below the cover member to above the cover member through the cover member, and wherein the attachment portion is attached to the upper rail such that the light emitter is arranged between the slide rail and the cover member. ### Claim 6 (depends on 1) The slide device according to claim 1, wherein a bolt that is configured to attach the slide seat for the vehicle is provided in the upper rail, and wherein a hole through which the bolt is passed is formed in the attachment portion, and the attachment portion is attached to the upper rail with the bolt. ### Claim 7 A light emitting device for a slide device, comprising: a light emitter; and an attachment portion that attaches the light emitter to an upper rail to which a slide seat for the vehicle is attached, wherein the attachment portion is attached to the upper rail such that the light emitter is arranged outside a slide rail to which the upper rail is slidably attached.
