<p>PROBLEM TO BE SOLVED: To promote space saving in occupied area for installation of a shading blade driving device, and to solve the problem of complicateness of assembling work of the shading blade driving device.SOLUTION: A shading blade driving device 1 includes a base plate 2 that contains a light path opening 2A, a shading blade 3 for opening or shielding the light path opening 2A, and drive means 4 for making the shading blade 3 linearly slide along one axis direction. The drive means 4 includes a rotor 40 having an arm part 42 which is rotatably pivoted and protrudes radially from a rotation center, a yoke 43 forming a pair of magnetic pole parts 43A, 43B around the rotor 40, a coil 45 wound on the yoke 43, a coil bobbin 44 containing a coil holding part 44A that holds the coil 45, and a lever member 46 for converting swinging of the arm part 42 to a linear displacement of the shading blade 3. The coil bobbin 44 includes a presser part 44B for pressing the rotor 40 and the lever member 46 along with the coil holding part 44A as one body.</p> |
