Claim 13:
14. A portable power tool comprising:
a drive mechanism that is configured to drive a tool accessory in an orbital and/or rotational motion;
a housing that houses the drive mechanism; and
a grip (i) rotatable around a rotating axis relative to the housing, (ii) attachable to the housing at least at a first angle relative to the housing around the rotating axis,
and (iii) that includes (a) a grip portion configured to be gripped by a user of the portable power tool, (b) a rod projecting from the grip portion along the rotating axis and (c) an engaging portion (i) projecting from the rod in a direction crossing the rotating axis and (ii) integral with the rod such that the rod and the engaging portion move as a single unit, wherein:
the housing comprises:
a first internal surface (i) defining a first internal space in the housing which can accommodate the engaging portion when the grip is at the first angle and (ii) configured such that, when the engaging portion is in the first internal space, the first internal surface restricts the rotation of the engaging portion around the rotating axis and the movement of the engaging portion from the first internal space in a first direction toward the grip portion by the contact of the engaging portion with the first internal surface;
a second internal surface defining a second internal space (i) in the housing, (ii) that is in communication with the first internal space, (iii) having a shape to allow the rotation of the engaging portion around the rotating axis when the engaging portion is in the second internal space and (iv) that is in a second direction opposite the first direction from the first internal space; and
a third internal surface (i) defining a third internal space in the housing and (ii) configured such that, when the engaging portion is in the third internal space, the third internal surface restricts the rotation of the engaging portion around the rotating axis by contact of the engaging portion with the third internal surface and permits the engaging portion to move along the rotating axis only when the grip is at a third angle relative to the housing that is different from the first angle;
wherein the third internal space is in communication with the second internal space and an outside of the housing.
