PURPOSE:To obtain an inexpensive lens mounting device which causes no shift of an optical axis, consists of few component parts, and also is assembled easily, by constituting a part of the outside diameter of a lens holder consisting of an elastic body to be slightly larger than the inside diameter of a lens barrel so as to insert said tube in the lens holder. CONSTITUTION:A lens 11 is fitted into a lens mounting groove 16 of a lens holder 14 consisting of an elastic substance such as rubber, etc. Subsequently, this lens holder 14 is inserted into the inside of a lens barrel 12, and a projection part 15 of the lens holder 14 is fitted into a holder mounting groove 13 of the lens barrel 12. In this way, it is possible to obtain an inexpensive lens mounting device which causes no shift of an optical axis, consists of few component parts, and also is assembled easily. |
