Consequently, even if batteries having different capacities are mounted on a battery mounting part (21) of the portable cutting machine, the position of the center of gravity of a main body (20) thereof will not differ greatly (or at all) in the left-right direction, and thus the weight balance is preserved and good handling is maintained, regardless of the size and/or weight of the battery that is mounted on the battery mounting part.

Abstract

A driving tool includes a driver, and a piston connected to the driver. The piston and the driver are housed within a cylinder such that the piston slidably moves within the cylinder by gas active pressure. The cylinder is positioned in an adjoining arear of an axis line of the piston. The cylinder is made of iron. Accordingly, a weight in the adjoining arear of the axis line of the piston is more than a cylinder made of aluminum or resin. Because of the large weight in the adjoining area of the axis line of the piston, a reaction force against a movement of the piston and a driving of the driver can be effectively restrained.

Abstract

A battery holder supported by a main body housing so as to be displaceable in an up-down direction has a main body extension, a holder lower portion at a lower part, and a terminal supported by the battery holder so as to be displaceable in the up-down direction. The battery holder has a first elastic body interposed between the main body housing and the battery holder, a second elastic body interposed between the battery holder and the terminal, and a third elastic body interposed between the holder lower portion and the main body housing. The first to third elastic bodies absorb impacts in the event of a drop, thereby reducing damage to the battery.

A battery pack includes at least one rechargeable battery cell disposed within an outer case. The outer case has an upper surface having at least one terminal opening that exposes at least one terminal electrically connected to the at least one rechargeable battery cell; a bottom wall; side surfaces extending perpendicularly from the bottom wall; and four protruding portions respectively protruding downward from four corners of the bottom wall. The four protruding portions are configured such that, when the four protruding portions of the battery pack contact a flat surface, only the four protruding portions contact the flat surface and a central portion of an exterior surface of the bottom wall does not contact the flat surface.
