A dust-free lens driving apparatus (10) includes a lens holder (14) for holding a lens, a housing having a central bore in which the lens holder (14) moves, and a film (26) having a first contact region (32), a second contact region (34) and a buffer region. The first contact region (32) is defined by a first peripheral portion of the film (26) and is used to sealingly attach the film (26) to and around the lens holder (14). The second contact region (34) is defined by a second peripheral portion of the film (26) and is used to sealingly attach the film (26) to and around a connection portion of the housing. The buffer region is defined by a remaining region of the film (26) between the first and second contact regions (32, 34) and is used to seal an exit of a gap between the lens holder (14) and the housing. |
