Abstract
PURPOSE:To easily attach a plastic lens to an accurate position by providing a recessed part provided with a notch for junction on the end face of a barrel and fitting and setting a projecting part of the plastic lens to this recessed part to adhere and fix the lens. CONSTITUTION:Three holes 23 for positioning and two holes 24 for junction are provided on the end face of a lens barrel 21, and a notch 25 is formed from the inside wall of each hole 24 to the outside peripheral surface of the barrel 21. Columnar bosses 28 for positioning and bosses 29 for junction are formed on the end face of the plastic lens 26 correspondingly to holes 23 and 24. At the time of assembling, bosses 28 and 29 are inserted to holes 23 and 24 to not only position the lens 26 in the diametral direction but also position the lens 26 in the optical axis direction through projecting parts 27. An adhesive is flowed from notches 25 to holes 24 to adhere bosses 29. Thus, the lens 26 is accurately and easily positioned and adhered.
