PURPOSE: To provide a connecting structure of a waterproof floor pan with which sure waterproofing is easily attained without receiving the influence of the dust and dirt sticking to junctures by using waterproof materials having elasticity in the junctures. CONSTITUTION: Ribs 11 are erected to project upward at the connecting ends of the one waterproof floor pan 1. The connecting ends of the other waterproof floor pan 2 are provided with sectionally U- -shaped superposing parts 21 which open downward and project upward. The waterproof materials 3 having elasticity are enclosed into the spaces 24 formed by superposing the superposing parts 21 on the ribs 11. Further, the ribs 11 and the superposing parts 12 are screwed by means of screws 5 and are thereby connected. |
