An object of the present invention is to provide a gap filler that includes a lock mechanism simpler in structure, inexpensive, and excellent in durability without needing electric power, and is structured to be capable of adjusting the protrusion amount of a gap filler plate. A first link mechanism section 40 converts linear motion of a driving slider 24 into swing motion of a swing end roller 46. A second link mechanism section 60 swings in cooperation with the swing end roller 46 on a roller contact surface 64 of a second link lever section 61, and an output end roller 67 changeable in attachment position presses a driven slider 62 fixed to a gap filler plate 16. In a fully protruded state and a fully stored state of the gap filler plate 16, the direction of acting force of the roller contact surface 64 pressing the swing end roller 46 aligns with a straight line connecting the swing end roller 46 and a swing shaft 44 of a first link lever section 43.
