PROBLEM TO BE SOLVED: To provide a locking mechanism for a plastic sash which forcibly corrects and closes irregular-shaped paper sliding doors. SOLUTION: In a locking mechanism which forms a first cremorne receiver 10a having a guide piece 16 which guides a paper sliding door to the closing side on a sash frame equivalent to the paper sliding door provided with a slide board and second cremorne receivers 10b and 10c having a locking groove 18 locked with a cremorne roller, the second cremorne receivers 10b and 10c are provided close to both ends of the inner side surface of a sash frame. The first cremorne receiver 10a is provided in the central part of the sash frame or near the sash frame. Third cremorne receivers 10d and 10e substantially equivalent to the construction of the second cremorne receivers 10b and 10c are laid out near the central part the second cremorne receivers 10b and 10c on both ends. When the paper sliding door is closed, a slid board is adapted to move slidingly. Then, the cremorne roller is engaged with the third cremorne receivers 10b and 10c, thereby forcibly correcting the deformation produced by the warping of the paper sliding door and locking the cremorne roller with the second cremorne receivers 10b and 10c.
