Abstract
A movement conversion device (4) for a motor-driven, hand-held, power tool (2) for converting a rotational movement into a linear reciprocating movement includes an axially reciprocating spindle (10), a motor-driven driving gear (20), an eccentric member (16) displaceably supported on the driving gear (20) and extending into the connecting link guide (14) provided at a spindle end for converting the rotational movement of the driving gear (20) into the reciprocating movement of the reciprocating spindle (10), the eccentric member (16) having a first position with respect to a rotational axis (D) of the driving gear (20) in which a distance (a) between the eccentric member (16) and the rotational axis (D) is greater than in at least one second position of the eccentric member (16), and a load-controlled spacing device associated with the eccentric member (16) for automatically adjusting the distance (a) between the eccentric member (16) and the rotational axis (D) of the driving gear (20).
