Portable, hand-guided working tool with a rear grip

A portable, hand-guided working tool comprising:

• a drive motor;
• a motor housing in which said drive motor is housed;
• said motor housing having a front side and a rear side when viewed in a direction of a longitudinal center axis of said working tool;
• a tool member connected to said front side of said motor housing and extending forwardly in a direction of said longitudinal center axis;
• said tool member driven by said drive motor;
• a rear grip connected by vibration damping elements to said rear side of said motor housing and extending rearwardly in the direction of said longitudinal center axis, said vibration damping elements positioned at a top side of said motor housing and providing an initial damping action between said rear grip and said motor housing;
• an abutment device comprising a first abutment member connected to said motor housing and positioned between said rear end and said rear grip and comprising a second abutment member connected to said rear grip and cooperating with said first abutment member for limiting a relative movement between said motor housing and said rear grip;
• wherein one of said first and second abutment members is a rigid abutment flange having a bore and wherein the other of said first and second abutment members is a bolt penetrating said bore, wherein said bolt, in a rest position of said housing and said rear grip, is radially spaced with play from an inner wall of said bore;
• wherein under load conditions movement of said motor housing relative to said rear grip is limited and a precise and stiff guiding of said working tool is provided by said bolt moving radially to overcome said play and rest at said inner wall of said bore;
• wherein said abutment flange is positioned in a plane extending parallel to a plane of said rear grip;
• wherein said abutment device further comprises a fastening flange having a connecting portion, wherein said connecting portion is connected to said abutment flange, wherein said fastening flange, said connecting portion, and said abutment flange together form a Z-shaped base body, and wherein said fastening flange and said abutment flange extend parallel and spaced at a distance to one another;
• wherein said connecting portion rests at said rear side of said housing;
• wherein said abutment flange is closer to said longitudinal center axis than said fastening flange;
• wherein said motor housing comprises a fastening projection and wherein said fastening flange engages said fastening projection.
