To provide an electric slide rail capable of holding the position of a slider against an external load.SOLUTION: An electric slide rail 1 has a rail 11, a slider 12, a screw assembly 35 supported by the slider, and an electric motor 36 that drives the screw assembly. The screw assembly includes: a connection shaft 37 connected to an output shaft 36A of the electric motor so as to be movable in an axial direction and rotated together with the output shaft; screw members 38, 39 that rotate in accordance with rotation of the connection shaft and are respectively engaged with screw engagement parts 57, 58 of the rail 11; an actuator 61 that moves the connecting shaft in the axial direction of the connecting shaft; a first engagement portion 62 provided in a gear case 41; and a second engagement portion 63 provided on the connecting shaft. When the connection shaft is in a first position, the first engagement portion and the second engagement portion are engaged with each other, and when the connection shaft is in a second position, the first engagement portion and the second engagement portion are separated from each other.SELECTED DRAWING: Figure 7
【課題】 外部荷重に対して、スライダの位置を保持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、スライダに支持されたねじアセンブリ35と、ねじアセンブリを駆動する電動モータ36とを有する。ねじアセンブリは、電動モータの出力軸36Aに、軸方向に移動可能に接続されると共に、出力軸と共に回転する接続軸37と、接続軸の回転に応じて回転すると共に、レール11のねじ係合部57、58に係合したねじ部材38、39と、接続軸を、接続軸の軸線方向に移動させるアクチュエータ61と、ギヤケース41に設けられた第1係合部62と、接続軸に設けられた第2係合部63とを有する。接続軸が第1位置にあるときに、第1係合部と第2係合部とが互いに係合し、接続軸が第2位置にあるときに、第1係合部と第2係合部とが互いに離間する。【選択図】 図7
