Claim 10:
11. A portable power tool, comprising:
a first handle extending in an elongated manner and configured to be held by a user;
an electric motor having a motor shaft that extends in an up-down direction and that is rotatable about a rotational axis;
a tool accessory configured to undergo an orbital and/or rotational motion in response to generation of a rotational driving force by the electric motor; and
a battery mounting part configured to be detachably attached to a battery that serves as a power source for the electric motor,
wherein:
an extension direction of the first handle is defined as a front-rear direction of the power tool,
the up-down direction is orthogonal to the front-rear direction, and the first handle and the tool accessory are arranged in series in the up-down direction,
in the up-down direction, a first side of the power tool on which the first handle is located is defined as an upper side, and a second, opposite side of the power tool on which the tool accessory is located is defined as a lower side,
the battery mounting part includes an upward mounting surface on which the battery is mountable, two guide rails configured to physically connect to the battery, and at least two terminals configured to be electrically connected to the battery in response to a surface of the battery that includes a connection interface being placed on the mounting surface,
the at least two terminals extend in a plane defined by the front-rear direction and a left-right direction that is perpendicular to the front-rear direction and perpendicular to the up-down direction, the plane being entirely above the electric motor in the up-down direction;
the two guide rails extend in the plane or in parallel to the plane;
the rotational axis of the motor shaft extends between the two guide rails and also between the at least two terminals;
the mounting surface is located at a position different from the first handle in the front-rear direction, and is located below an upper side of the first handle in the up-down direction,
a second handle arranged below the battery mounting part in the up-down direction,
the tool accessory has a generally rectangular shape, and a longitudinal direction of the generally rectangular shape extends in the front-rear direction when viewed in the up-down direction, and
in the front-rear direction, a first lateral side of the power tool on which the battery mounting part is located is defined as a front side,
a second, opposite lateral side of the power tool on which the first handle is located is defined as a rear side, and
the battery mounting part is configured such that the battery is mountable by sliding it from the front to the rear in the front-rear direction.
