Seat slide device

A seat slide device comprising:

• a long-shaped lower rail having an upper opening and configured to be fixed to a floor of a vehicle;
• and
• an upper rail configured to be attached to a seat, and slidingly movable along the lower rail,
• the lower rail having:
• a bottom wall formed in a generally planar shape over an overall length thereof, the bottom wall having an upper surface and opposite sides,
• a protruding object protruding from the upper surface of the bottom wall,
• first and second opposite sidewalls extending up respectively from the opposite sides of the bottom wall, the opposite side walls being formed respectively with upper ends,
• opposite bended portions extending in and down respectively from the upper ends of the first and second opposite sidewalls, the opposite bended portions being formed respectively with lower distal ends, the pair of opposite bended portions defining the upper opening and a space for accommodating the protruding object protruding from the upper surface of the bottom wall, and
• a foreign-object catching member provided on the upper surface of the bottom wall to catch a foreign object that falls inside the lower rail through the upper opening, the foreign-object catching member having an elastic body which:
• is disposed between the opposite bended portions;
• and
• has an upper end lying at a position higher than the lower distal ends formed respectively on the opposite bended portions so that the elastic body, during the slide movement of the upper rail, allows a foreign object caught by the elastic body to be pushed by the upper rail and moved together with the upper rail, while preventing the foreign object from being stopped by hitting against the protruding object.
