To provide an electric slide rail capable of suppressing variation in the position of contact between a screw member and an engagement hole.SOLUTION: An electric slide rail 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 part 57. The screw engagement part includes a plurality of engagement holes 59 formed in each of a pair of side walls 17 and aligned in a first direction. Each engagement hole extends while being inclined with respect to a second direction orthogonal to the first direction. Each engagement hole includes a first portion 61 disposed at a center in a longitudinal direction, and a pair of second portions 62A and 62B disposed on both sides of the first portion. A width of each second portion in the first direction is less than a width of the first portion in the first direction. The screw member does not abut on an edge part 65 of the engagement hole in the first portion, and abuts on the edge part of the engagement hole in at least one of the second portions.SELECTED DRAWING: Figure 2

    【課題】 ねじ部材と係合孔との接触位置の変動を抑制することができる電動スライドレールを提供する。【解決手段】 電動スライドレール1は、レール11と、スライダ12と、ねじ部材38を含むねじアセンブリ35と、電動モータ36と、ねじ係合部57とを有する。ねじ係合部は、一対の側壁17のそれぞれに形成され、第1方向に配列された複数の係合孔59を有する。係合孔のそれぞれは、第1方向と直交する第2方向に対して傾斜して延びている。係合孔のそれぞれは、長手方向における中央に配置された第1部分61と、第1部分の両側に配置された一対の第2部分62A、62Bとを有する。第2部分のそれぞれの第1方向における幅は、第1部分の第1方向における幅よりも小さい。ねじ部材は、第1部分において係合孔の縁部65と当接せず、第2部分の少なくとも一方において係合孔の縁部に当接する。【選択図】図2
