Blade driving device, camera device and electronic apparatus

A blade driving device, comprising:

• a first member comprising a plurality of adjustment pins positioned on a circumference centered on an optical axis of a lens body;
• a second member comprising a plurality of shaft pins positioned in correspondence with the adjustment pins;
• and
• a plurality of blades, each of the blades comprising an adjustment hole in which one of the adjustment pin is movably fitted and a shaft hole in which one of the shaft pins is rotatably fixed, and being combined to form a light passing hole in the center thereof through which light incident on the lens body passes,
• wherein the first member and the second member are combined with each other so that one rotates relative to the other centered on the optical axis of the lens body, and the other has a mechanical stopper that stops the rotation of the one by making the one touch on the other;
• the adjustment hole has a first section extending from a first position and a second section extending from a second position,
• when the adjustment pin is in the second section, the adjustment hole of the second section moves along a trajectory where the adjustment pin moves, a diameter of the light passing hole is minimum, and at this time, the first member and the second member touch on each other at the mechanical stopper.
