MOUNTING STRUCTURE OF SHUTTER OPENING/CLOSING DEVICE
To improve the durability of the mounting structure of a shutter opening/closing device with a built-in swingable winding drum.SOLUTION: An opening/closing device 6 is built into one end side of a winding drum 30 via a mounting base 7. The mounting base 7 includes a cylindrical portion 70. A shaft portion 60 of the opening/closing device 6 is fixed to a connecting portion 31 fixed to the inner peripheral surface of the winding drum 30. The opening/closing device 6 is positioned in the cylindrical portion 70 and is supported swingably at one end side. A plate-like portion 8 is provided at the other end side of the cylindrical portion 70. The plate-like portion 8 is positioned outside the end portion of the winding drum 30. The plate-like portion 8 is fixed to a fixed portion 9 while being in surface contact therewith. The plate-like portion 8 has a shape in which the stress generated between the plate-like portion and a fixation part of the fixed portion is dispersed as compared with the case where the plate-like portion is rectangular.SELECTED DRAWING: Figure 5
【課題】揺動可能な巻胴内蔵型のシャッター開閉機の取付構造の耐久性を向上させる。【解決手段】巻胴３０の一端側には、取付台７を介して開閉機６が内蔵されており、取付台７は筒状部７０を備え、開閉機６の軸部６０は巻胴３０の内周面に固定された連結部３１に固定されており、開閉機６は、筒状部７０内に位置して一端側に揺動可能に支持されており、筒状部７０の他端側には板状部８が設けてあり、板状部８は、巻胴３０の端部よりも外側に位置しており、板状部８は、被固定部９に面接触した状態で固定されており、板状部８は、方形であった場合に比べて、前記板状部と前記被固定部の固定部位に生じる応力が分散された形状を備えている。【選択図】図５
