PROBLEM TO BE SOLVED: To provide a camera focal plane shutter capable of improving the durability of a shutter by efficiently relaxing a shock when exposure operation is completed.SOLUTION: A blade 4 is rotatably attached to a first arm 2 and a second arm 3 by coupling shafts 2a and 3a. Since the deformation of each arm or the blade can be suppressed even when a force distorting the blade acts so as to reduce an interval between the two arms since the second arm 3 can be contacted with a buffer member 6 attached to the first arm 2 after the first arm 2 are contacted with a stopper 1c when exposure operation is completed, the durability of a shutter can be further improved. |
