Provided is a floorboard fixing device which restricts floorboard movement caused by external force that is caused by everyday use and which, when expansion, shrinkage, or the like occurs in a floorboard, is capable of fixing the floorboard onto a support member like a joist in such a way as to be able to permit movement of the floorboard. More specifically, provided is a floorboard fixing device (1) that fixes a floorboard (4) wherein a slit (41) is longitudinally formed on both side surfaces (40) in the width direction. A bridge piece (3) and a spacer piece (2) are integrally formed by a flexible synthetic resin material into an approximately cross shape, the aforementioned bridge piece (3) being to insert into the slit (41) formed on the side surface (40) of each of two floorboards which are disposed adjacent to each other, and the aforementioned spacer piece (2) protruding toward the front surface and the back surface of each floorboard from an intermediate position, in the width direction, of the bridge piece (3) and being held between the side surfaces of the two floorboards. There is formed an insertion hole (21) which is cut through the spacer piece (2). A fastener is inserted into the insertion hole (21). On a side surface (23) of the spacer piece (2), this side surface (23) being in contact with the side surface (40) of one of the floorboards, there are formed, in the direction which perpendicularly intersects with the longitudinal direction of the aforementioned side surface (40) of the floorboard, a plurality of protrusions (22, 22') which form a row of protrusions located at predetermined intervals. |
