Abstract
A shock absorber for a starter is presented. The shock absorber includes a rotary disk, a stationary disk and a disk spring. The rotary disk is pressed by the disk spring against a stationary disk to generate frictional force when the rotary disk is rotated by an excessive shock thereby absorbing the shock. The rotary disk has a plurality of press-formed rectangular dimples at a surface opposite the stationary disk, and each side of each the rectangular dimple inclines to a direction of rolling of the raw material of the rotary disk.
