Claim 13:
14. A motion converter of a saber saw, the motion converter configured to convert a rotational motion of an output shaft of a drive motor of the saber saw into a reciprocating motion of a spindle of the saber saw, the spindle configured to clamp one end of a saw blade in a cantilevered manner such that the saw blade extends away from a housing of the saber saw, the motion converter comprising:
an eccentric element driven by the output shaft rotationally about an axis of rotation with a driver part arranged eccentrically to the axis of rotation; and
a pendulum element with a first end mounted pivotably at a bearing point and a coupling point connected to the spindle, wherein:
the pendulum element has a guide element configured to guide the driver part;
the guide element is arranged between the bearing point and the coupling point;
the bearing point and the coupling point define a first axis of the pendulum element; and
the guide element allows motion of the driver part relative to the pendulum element in a direction along the first axis of the pendulum element, and largely prevents motion of the driver part relative to the pendulum element in a direction perpendicular to the first axis of the pendulum element.
