BRAKING DEVICE, AND SHIELDING DEVICE USING SAME

摘要

Provided is a braking device that, in order to reduce an operating force during a pulling operation and stabilize the behavior of the device during an automatic lowering, is configured such that a cord is released in an unbent state. Also provided is a shielding device using the braking device. This braking device brakes the movement of a cord and is provided with a motion converting unit that converts movement of the cord into motion of another member. The motion converting unit is provided with a clamping body that clamps the cord. The clamping body is configured such that the clamping state changes such that when the cord and the clamping body are moving relative to each other in one direction, the clamping body clamps the cord, and when the cord and the clamping body are moving relative to each other in the other direction, the cord is released in an unbent state.
