PROBLEM TO BE SOLVED: To provide a door mechanism for a greenhouse having high hermetic salability and facilitating the going in and out of a working machine. SOLUTION: This door mechanism is obtained by forming each cut part 3 in the suitable direction of a gable surface 2 and arranging a fastener 4 along the cut part 3. Thereby, at least either one of film parts 5 provided with the cut part 3 as a boundary can readily be opened and closed by opening and closing the fastener 4 in spite of a simple constitution manufacturable at a low cost.
