摘要： A focal-plane shutter capable of suppressing production of foreign matter is provided. The focal-plane shutter includes a base plate, rear curtain drive arms, a blade that is driven by the rear curtain drive arms, and an elastically deformable cushioning member that comes into contact with the blade that moves from a retracted position to an unfolded position. The blade extends in a first direction. The rear curtain drive arms are swingable around the centers of swing motion provided on one side of the blade in the first direction. The cushioning member has a contact section that comes into contact with a side edge of the blade, a holding section that is arranged on the side opposite the blade with the contact section therebetween, and a connecting section that connects the contact section and the holding section to each other. The connecting section inclines with respect to a second direction perpendicular to the first direction and extends toward the centers of swing motion.
