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, and swings the swing end roller 46 in cooperation with a second link mechanism section 60. An output end roller 67 of the second link mechanism section 60 engages in a guide groove 66 in a driven slider 62 fixed to a gap filler plate 16 to move the gap filler plate 16 linearly. 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 to act as a lock. The guide groove 66 is formed orthogonal or almost orthogonal to movement directions of the gap filler plate 16.
