PROBLEM TO BE SOLVED: To provide a surface lattice body to be easily constructed at a lower installation cost while reducing a sense of blockage, and to provide an opening part device.SOLUTION: An opening part device 1 includes a sash frame 3, sliding sashes 5a-5d provided in the sash frame 3, and surface lattice bodies 7a, 7b. The surface lattice bodies 7a, 7b are slidably provided on the sash frame 3 at the outdoor side of the sliding sashes 5a-5d, and each have a width size greater than the width size of each of the sliding sashes 5a-5d. The surface lattice bodies 7a, 7b are locked to the sash frame 3 in the state of covering areas ranging from the door edge positions of the sliding sashes 5a-5d being closed beyond a meeting part 73 to a cross-direction middle between the adjacent sashes. |
