Abstract: A jigsaw includes a jigsaw main body, a handle, and a battery. The jigsaw main body includes a housing, a motor disposed inside the housing, and a battery mounting portion having a first mounting surface facing downward. The handle is disposed at an upper portion of the jigsaw main body and above the motor. The battery has a second mounting surface and supplies the motor with an electric power. The battery is slidable along the first mounting surface and mountable to the battery mounting portion with the first and second mounting surfaces facing each other.

Abstract: A sander is of a palm type, and its upper portion is configured as a holding portion. A battery attachment portion to which a battery having an elongated shape is attachable is oriented at an angle not less than 0 degrees with respect to a vertical direction, such that if a longitudinal direction of the battery is angled, a lower portion of the battery is in a position shifted inward farther than an upper portion of the battery.

Abstract: A long rod grinding machine reduces the likelihood of dust escaping and falling. The long rod grinding machine includes a head and a rod having an end connected to the head and extending in a front-rear direction. The head includes an electric motor, a pad movable with a driving force from the electric motor, a vertical wall surrounding a radially outer edge of the pad, and a contact member located between the vertical wall and the pad and surrounding the radially outer edge of the pad. The contact member includes a brush holder having one or more through-holes extending in a radial direction of the pad, and a brush located below the brush holder and having a lower end located downward from a lower end of the vertical wall.

Abstract: A long rod polishing device includes a prismatic or columnar battery, a battery mounting portion, an electric motor, a pad, and a rod portion. The battery is mountable to the battery mounting portion. The electric motor is driven by an electric power from the battery. The pad has a polishing surface and moves by a driving force from the electric motor. The rod portion has an end portion to which the pad is coupled. The battery mounted to the battery mounting portion has a longest side. The longest side has a direction so as to form an angle with respect to a second imaginary straight line. The second imaginary straight line is perpendicular to both of a center axis of the rod portion and a first imaginary straight line. The first imaginary straight line is perpendicular to the center axis and parallel to the polishing surface of the pad.

Abstract: A jigsaw includes a motor, a rod having a blade attached thereto, a power transmission portion that converts rotation transmitted from the motor to vertical movement of the rod to vertically move the blade, and a counterweight that moves vertically in a direction of the vertical movement of the rod outside a range of the vertical, movement of the rod and the blade. At least a part of the counterweight is disposed so as to cross an extended line of a trajectory of the vertical movement of the rod. The counterweight moves vertically independently of the vertical movement of the rod which is produced by the power transmission portion.
