Abstract:
A vane driving device includes: a board having an opening; a blade changing an area of the opening, having a cam slot, and being elastically deformable; and a drive member transmitting a drive force from a drive source to the blade, and having a drive pin engaging the cam slot. The drive member is stopped by contacting the drive pin with at least one of end portions of the cam slot, when the blade is located in a fully opened state or in a small aperture state.
