<p>A first position determining part (43) formed on a first frame piece (40c1) on a frame side has a width (W11) in another direction Y orthogonal to a bending direction X set at a standard width (W0) and width (W12) in the bending direction X formed into an elongated hole. A first position determining part (23) formed in a first frame piece (22c1) on a lens side has a width (W21) in the other direction Y set at (W0). In addition, a second position determining part (44) formed in a second frame piece (40c2) has a width (W15) in one direction X orthogonal to the bending direction Y set to the standard width (W0) and width (W16) in the bending direction Y formed into an elongated hole. A second position determining part (24) formed in a second frame piece (22c2) on the lens side has a width (W25) in the one direction X set to the standard width (W0).</p> |
