The present invention is intended to implement a gap filler having a lock mechanism that is simple in mechanical structure and is capable of adjusting the protrusion amount of a gap filler plate. A swing body 40 has a driving end section engaged with a driving end roller 27 of a linearly moved driving slider 25, and has a driven end section engaged with a guide groove 66 in a driven slider 62 coupled to the gap filler plate 16 by a driven end roller 46 changeable in installation position in a displacement installation-capable direction. The gap filler has an inverse operation preventive structure that, when the gap filler plate is in a fully protruded state and a fully stored state, enables only forward motion transfer from the driving slider 25 to the swing body 40. The guide groove 66 is formed in a direction orthogonal or almost orthogonal to the forward and backward movement directions of the gap filler plate 16, and the displacement installation-capable direction and the direction of the guide groove 66 are parallel to each other in the fully stored state.
