[Task] To provide an electric slide rail device capable of suppressing changes in the contact position between a screw member and an engagement hole. An electric slide rail device 1 includes a rail 11, a slider 12, a screw assembly 35 including a screw member 38, an electric motor 36, and a screw engagement portion 57. The screw engagement portion includes a plurality of engagement holes 59 formed in each of the side walls and arranged in the first direction. Each engagement hole extends at an angle with respect to a second direction perpendicular to the first direction. Each engagement hole includes a first portion 61 located in a longitudinal central portion thereof and a pair of second portions 62A and 62B located on both sides of the first portion. A width of each second portion in the first direction is smaller than a width of the first portion in the first direction. The screw member does not abut against an edge portion 65 of the engagement hole in the first portion, and abuts against the edge portion of the engagement hole in at least one of the pair of second portions.
[任务]提供一种能够抑制螺杆构件与卡合孔之间的接触位置的变化的电动滑轨装置。[技术方案]电动滑轨装置1包括轨道11、滑动件12、包括螺杆构件38的螺杆组件35、电动马达36和螺杆卡合部57。螺杆卡合部包括形成在每个侧壁中且沿第一方向布置的多个卡合孔59。每个卡合孔相对于垂直于第一方向的第二方向成角度地延伸。每个卡合孔包括位于于其纵向中央部分中的第一部分61和位于第一部分的两侧上的一对第二部分62A和62B。每个第二部分在第一方向上的宽度小于第一部分在第一方向上的宽度。螺杆构件在第一部分中不抵靠卡合孔的边缘部65,并且在所述一对第二部分的至少一个中抵靠卡合孔的边缘部。
