Abstract
A focal-plane shutter that has a shutter base plate that has an opening; a shutter blade that opens/closes the opening; a blade arm that pivotally supports the shutter blade; and a blade drive member that has a drive pin that is connected to the blade arm. The blade drive member rotates the blade arm so as to drive the shutter blade. The blade arm has a connection hole into which the drive pin is inserted; and a restriction member that is between an inner circumferential surface of the connection hole and an outer circumferential surface of the drive pin and that restricts the movement of the drive pin inside the connection hole.
