A shock absorbed device for reciprocating a driven member includes a bidirectionally rotatable driving pulley, a pair of fixed pulleys between which the driven member is disposed, an oscillating pulley arranged between the driving and fixed pulleys, and at least a wire connecting all said pulleys. The oscillating pulley is mounted for free movement along a path from a neutral position centrally within its path in response to rotation of the driving pulley in either direction thereof. |
