Sliding device

A sliding device configured to support a seat body of a vehicle seat in a slidable manner, the sliding device comprising:

• a fixed rail configured to be fixed to a vehicle, the fixed rail comprising an opening opened upward, the opening being arranged in a longitudinal direction of the fixed rail;
• a movable rail to which the seat body is configured to be fixed, the movable rail being slidable with respect to the fixed rail;
• a shutter configured to close the opening, the shutter being slidable with respect to the fixed rail by receiving a force from the movable rail;
• an engaging body provided to either one of the shutter and the fixed rail, the engaging body being displaceable between an engaged position, in which the engaging body is engageable with an engaged portion provided to the other of the shutter and the fixed rail, and a disengaged position, in which the engaging body is displaced from the engaged position;
• a resilient element configured to produce a resilient force maintaining the engaging body in the engaged position;
• and
• a pressing portion provided to the movable rail or the shutter, the pressing portion contacting with a pressed portion provided to the engaging body when the movable rail slides, to thereby displace the engaging body to the disengaged position.
