A self-compensating balancer for a disk player is provided and includes a supporting plate fixed to a rotating shaft of a spindle motor for supplying rotary power to a disk. Pivot pins are installed in the supporting plate and two or more pendulums are arranged around the supporting plate. The pivot pins and pendulums are linked by connectors, such that upon rotation of the shaft, the connectors are elastically transformed and a centroid of the pendulums faces a centroid of the disk, centered around the rotating shaft of the spindle motor, due to a centrifugal force.
