A portable, hand-guided working tool has a drive motor and a motor housing in which the drive motor is housed. The motor housing has a front side and a rear side when viewed in the direction of the longitudinal center axis of the working tool. A tool member is connected to the front side of the motor housing and extends forwardly in the direction of the longitudinal center axis. The tool member is driven by the drive motor. The rear grip is connected by vibration damping elements to the rear side of the motor housing and extends rearwardly in the direction of the longitudinal center axis. An abutment device includes a first abutment member connected to the motor housing and positioned between the rear end and the rear grip and includes a second abutment member connected to the rear grip and cooperating with the first abutment member for limiting a relative movement between the motor housing and the rear grip.
