Abstract
A reciprocating saw including a motor defining a motor axis, the motor including a front end and a back end, the front end including a front face defining a first vertical plane, and the back end including a rear face defining a second vertical plane parallel to the first vertical plane. The reciprocating saw also includes a dual-eccentric scotch yoke mechanism coupled to the motor. The scotch yoke mechanism includes a spindle driven to reciprocate relative to the motor along a spindle axis parallel to the motor axis, the spindle including a rear end nearest to the motor. The scotch yoke mechanism also includes a counterweight driven to reciprocate relative to the motor. The spindle is arranged above the motor. As the spindle reciprocates forward and backward, the rear end extends into a space defined between the first and second vertical planes.
