を特徴とするシヤツタの緩衝装置。 A torque accumulating coil spring is provided between a hoisting wheel for hoisting the slat curtain and a fixed shaft rotatably supporting the hoisting wheel, and accumulating torque to reduce the weight load of the slat curtain. In the opening/closing structure of the shutter connecting the above-mentioned fixed shaft, a shock-absorbing coil spring that applies a spring force in the opposite direction to the biasing force of the torque accumulating coil spring is attached to the fixed shaft with one end of the shock-absorbing coil spring connected to the hoisting wheel. At the same time as winding, the tongue of the slider projects into the coil gap of the buffer coil spring in a state where it can abut against a hook provided at the other end of the buffer coil spring, and the slider is attached to the fixed shaft. A shutter comprising a fixing means supported movably in the axial direction on a loosely fitted ring, and fixing the ring to the fixed shaft while being rotated to a desired position around the fixed shaft. Buffer device.
