Method for fabricating lens unit, lens unit and imaging apparatus

摘要

The present invention provides a method for fabricating a lens unit in which an inter-barrel member can be fixed with a high degree of accuracy without enlarging the lens barrels and the accuracy of the dimension of the inter-barrel member is not required. The method comprises the steps of: disposing an inter-barrel member 11 in a gap "g" defined between a front lens barrel 7 on a subject side in an optical-axis direction x and a rear lens barrel 8 on an imaging surface side in the optical-axis direction x; bringing the inter-barrel member 11 into close contact with one of the front lens barrel 7 and the rear lens barrel 8 in the optical-axis direction x; inserting a resilient member 12 into a space in the optical-axis direction x between the inter-barrel member 11 and the other of the front lens barrel 7 and the rear lens barrel 8; and fixing the front lens barrel 7 and the rear lens barrel 8 integrally with each other to compress the resilient member 12 in the optical-axis direction x.
