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 ).
