PROBLEM TO BE SOLVED: To provide a pickup lens braking device capable of effectively suppressing the unwanted displacement of the pickup lens and always precisely recording/reproducing information. SOLUTION: This device is constituted so that in a pickup lens driving device constituted so that a hold member 11 holding the pickup lens 8 is supported displaceably in the prescribed direction for a fixed member 10, and a driving coil 13 or a driving permanent magnet 14 is provided on the hold member 11, and the driving permanent magnet 14 or the driving coil 13 is provided on the fixed member, and the hold member 11 is made to be driven in the prescribed direction by an electromagnetic action between the driving coil 13 and the driving permanent magnet 14, a non-magnetic conductive part 31 is provided on the hold member 11 or the fixed member 10, and a braking permanent magnet 32 is provided on the fixed member 10 or the hold member 11 opposite to the non-magnetic conductive part 31 through a prescribed gap. |
