PROBLEM TO BE SOLVED: To easily drain muddy water with the smooth flow of water for cleaning the upper face of a mat by forming a front side corresponding part of a driver's cab as an inclined face inclining downward toward the rear, and bending upward the peripheral edge excluding a doorway part. SOLUTION: The upper face of a front part 2a of opening parts 3, 4, 5 is formed as an inclined face inclining downward toward the rear at a specified angle, and a rear part 2b is consecutively installed to the front part 2a through a borderline 6. In this case, a triangular side part 2c is consecutively installed to the rear part 2b between the front part 2a and the front side of a wide part of a left side part facing a doorway part 7, through borderlines 8, 9. An upward bent part 11 is provided at the peripheral edge of a floor mat 2 excluding the doorway part 7, and upward bent parts are also provided at the peripheral edges of the opening parts 3, 4, 5. Sediment and wash water are therefore prevented from entering the rear face form the peripheral edge of the mat 2 and the peripheral edges of the opening parts 3, 4, 5.
