  • Publication number: 20200139855
    Abstract: A sliding device includes a fixed rail, a movable rail, a shutter to close an opening of the fixed rail, an engaging body including a pressed portion, an engaged portion, a resilient element, and a pressing portion provided to the movable rail or the shutter. The shutter is slidable relative to the fixed rail by receiving a force from the movable rail. The engaging body is provided to one of the shutter and the fixed rail, and the engaged portion is provided to the other. The engaging body is displaceable between an engaged position where it is engageable with the engaged portion and a disengaged position displaced from the engaged position. The resilient element produces a resilient force maintaining the engaging body in the engaged position. The pressing portion contacts with the pressed portion when the movable rail slides, thus displacing the engaging body to the disengaged position.
