り装置。[Scope of Claim for Utility Model Registration] (1) A base on which an optical axis aperture is formed, aperture blades disposed in the optical axis aperture so as to be openable and closable, and arranged around the optical axis aperture in a direction intersecting the optical axis. A movable member is formed by fixing a permanent magnet to an annular apex portion of a synthetic resin base formed in an annular shape, which is swingably supported on a support shaft of In an aperture device that has a coil provided on the base side that causes the vibration to occur, and a transmission member that transmits the oscillating motion of the movable member to the aperture blades, the permanent magnet of the movable member is spaced apart in the direction of the coil winding. A camera aperture device characterized by being composed of a plurality of magnets. (2) The aperture device for a camera according to claim (1), which comprises a plurality of magnets embedded in the synthetic resin base. (3) A camera according to claim 1, wherein a plurality of fitting grooves are formed in the annular apex portion of the synthetic resin base, and a magnet is fixed to each of the fitting grooves. Squeezing device. (4) Scope of Utility Model Registration Claim (1), in which permanent magnets are attached to a pair of left and right annular apexes divided into two by the support shaft of the synthetic resin base so that the left and right opposing polarities are opposite to each other. The camera diaphragm device described in items (3) to (3) above.
