Abstract

An auto-focus device comprises a lens carrier (LC) slidably received for a reciprocating motion within a stationary housing frame (HF), said reciprocating motion being provided by an actuator that includes at least one V-shaped SMA actuating member (SW), the lens carrier (LC) being provided with a guide pin (GP) embedded in a corner projection (CP) and whose ends are received within bushing holes (BH) formed respectively in the housing frame (HF) and in a bottom plate (BP).
