Patent attributes
An autofocus actuator includes a cover which is provided with elastic tabs in addition to protrusions to which a stopper attached to a holder with a lens unit abuts when the holder is excessively displaced by, for example, a fall of an electronic equipment provided with the autofocus actuator. The protrusions are provided on the peripheral edge of an opening formed in the cover, and the elastic tabs are also provided on the peripheral edge of the opening. Each of the elastic tab has one end which is supported on the cover and the other end which protrudes from the peripheral edge of the opening in a cantilever manner so that the other end makes abutment with the stopper attached to the holder before the stopper makes contact with the protrusions to thereby absorb a shock applied to the holder.
