シヤツターのブレーキ装置。 A brake lever 1 is pivotally supported on a brake shaft 4 installed on the shutter base plate 3 and comes into contact with the shutter blade drive lever at the end of its operation to provide braking.
, a brake spring 10 interposed between the base plate and the brake lever, prevented from rotating and supported by the brake shaft, and a brake spring 10 disposed directly on both sides of the brake lever and supported by the brake shaft 4. The pair of friction plates 11 and 12 and the friction plate on the opposite side of the main plate are pressed to apply a deforming elastic force to the brake spring, and a predetermined frictional resistance force is applied when the brake lever pivots. In a brake device for a focal plane shutter, the brake device includes a fixing member 13 fixed to the brake shaft by a fixing means fixed to the tip of the brake shaft such that lubricant is retained on at least one of the friction plates. A focal plane shutter brake device that features holes.
