A fitting structural body structured to form a frame as a whole, including corner portions of a non-linear part, using fittings for gripping a flexible sheet, which inflates in accordance with supplying a fluid and deflates in accordance with discharging the fluid, and the fittings fixed to a target structure of the fitting structural body, wherein the fittings on the both sides of the non-linear part are unified to remove acute portions at the corner portions of the non-linear part formed along a longitudinal direction of the frame.
A flexible sheet inflatable gate, comprising:
- a flexible sheet for inflating in accordance with supplying a fluid and deflating in accordance with discharging the fluid;
- and
- a fitting structural body structured to form a frame as a whole using fittings for gripping the flexible sheet, and being fixed to a target structure of the inflatable gate, wherein the fittings are unified to remove acute portions at corner portions on the both sides of and non-linear part formed into a non-linear shape along a longitudinal side of the frame, and a contacting part of the fittings, which contacts with a part of adjacent fittings to the fittings, is inclined in relation to a fixing direction of the fittings so as to press the adjacent fittings against the target structure.
