PURPOSE:To easily assemble a device, to easily adjust the position of an optical element and to enhance impact resistance and vibration proofing property as for the device constituted so that the optical element is held by a holding device. CONSTITUTION:Plural holes 1b are provided on the outside circumferential surface of the optical element 1 at almost equal intervals and one end part of a supporting member 4 whose other end part is inserted into the hole 1b is fixed to the optical element holding member 2. Then, the supporting member 4 is fixed to the holding member 2 through spherical washers 5 and 9. Besides, a sleeve 3 or an adhesive material is arranged in a gap between the hole 1b and the supporting member 4. |
