PURPOSE:To remove the positional shift of a lens and to provide a highly accurate photographing lens by arranging an elastic member for contacting the lens against a body on the peripheral part of the photographing lens rotationally symmetrically around an optical axis. CONSTITUTION:A ring-like hook part 20i formed on the periphery of a lens holder supporting member 20c through the elastic member 20j and the elastic member 20j is formed as a rotationally symmetrical shape by 120 deg. around the center axis of a cylindrical part 20h. When the hook part 20i is fixed on the body, the cylindrical part 20h is inhibited to move in a direction rectangular to a shaft k and is moved properly in the vertical direction and the center axis k is inclined to k' or k'' to attain so-called gyro-motion. Consequently, the positional shift of the photographing lens is not generated and the highly accurate photographing lens can be obtained. |
