PROBLEM TO BE SOLVED: To hold rectangularity between a lens bearing and a support shaft, and to easily hold mutual parallelity even in plural lens fitting holes by providing the lens fitting hole provided with a lens receiver and providing three projection parts on the lens receiving part. SOLUTION: This lens holder 1 is provided with the bearing 2 and the lens fitting holes 4a, 4b provided with the lens receiver 3, and the lens receiver 3 is formed on an upper part plane of a hollow disk concentrically provided on the inner peripheral surface of the lens fitting holes 4a, 4b. Further, three projection parts 5 are arranged on the circumference of the lens fitting hole or the lens receiver at a uniform angle of nearly 120 deg.. Then, the lens is fixed to a fixed surface. Thus, the lens is fixed horizontally by horizontally providing the height of three projection parts, and the parallelity of respective lenses are held even in plural lenses. |
