Abstract: In a thin image capture lens feeding device, wear can be avoided, even when switching between a normal image capture mode and a macro image capture mode is repeated. A lens retention housing may move back and forth when rotated relative to a holder. The holder, in sliding coupling with the lens retention housing, holds the lens retention housing. Enclosed between a pressing cover and the holder are a spacer, micro-coil spring set, and lens retention housing; by coupling the pressing cover and the holder by claw portions, an integrated image capture lens feeding device is assembled. The spacer and lens retention housing are integrated by a linking hole and linking rod, configured such that the lens retention housing and the spacer rotate simultaneously by the same amount, so that wear at the contact portions between the spring means and spacer is avoided.
