Abstract
A blade driving device has a first member with a plurality of adjustment pins provided on a circumference centered on an optical axis of a lens body. The blade driving device includes a second member with shaft pins corresponding to the adjustment pins and a plurality of blades. Each blade has an adjustment hole movably fitting the respective adjustment pin and a shaft hole in which the shaft pin is rotatably fixed. The blades combine to form a light passing hole in the center, through which light incident on the lens body passes. The first member and the second member are combined so that one member rotates relative to the other member with rotation centered on the optical axis of the lens body. The other member has a mechanical stopper that stops the rotation of the one member.
