Abstract
A housing structure for miniature lens focus module has a top portion formed into a stepped structure, that is, the housing has a size-reduced topmost portion relative to the rest rear portion thereof and has a shoulder portion formed therein, so that a plate-shaped spring element for holding a lens holder can be directly connected to the shoulder portion in the housing to keep away from the topmost portion of the housing by a predetermined distance and define an operation space between the shoulder portion and the topmost portion, allowing the lens holder and accordingly a lens held thereto to axially linearly move within the operation space to focus light. The spacer provided in the prior art lens focus module can be omitted to reduce the cost and the assembling procedures of the lens focus module.
