<p>A lens holding device having a lens housing (12) with one opening (14) in the direction of the optical axis (J) and a lens (11) press-fitted into the lens housing (12) from the opening (14). The lens housing (12) has a tapered inner peripheral surface (16), a holding surface (17), and a positioning section (18). The lens (11) is press-fitted into the lens housing (12) from the one opening (14) into the direction in which the inner diameter of the tapered inner peripheral surface (16) increases. The lens (11) stops at a predetermined position, or at a contact surface (18A) of the positioning section (18), and a holding surface (17) engages an outer peripheral surface (11A) of the lens (11) to hold it.</p> |
