A robotic vacuum () includes a main body () having a suction port () in a bottom surface (B) thereof; a storage unit () housed in the main body and configured to store dust and debris suctioned in via the suction port (); and at least one wheel () that supports the main body (). The main body () has a width Wb in a first direction that is parallel to a rotational axis (AX) of the wheel (), the storage unit () has a width Ws in the first direction, the main body () has a height Hb in a second direction that is perpendicular to the rotational axis (AX) and perpendicular to the first direction, and the storage unit () has a height Hs in the second direction. The width Wb is 470-600 mm, and the condition 0.5&#xd7;Wb&#x2264;Ws&#x2264;0.7&#xd7;Wb is satisfied.

Robotic vacuum

A motor housing of housings forming an outer casing of a tool main body is provided with two battery attachment portions allowing attachment of rechargeable batteries. The two battery attachment portions are configured as slide attachment type battery attachment portions. The two battery attachment portions are suited to slide attachment type rechargeable batteries that are attached through sliding. The two rechargeable batteries are attached in the right-left direction of the tool main body so that the two rechargeable batteries can be arranged side by side in the direction in which the tool main body extends.

Cutting tool

A reciprocating tool includes a motor, a crank, a connecting rod, a rod, a tool bit, and a counter weight. The tool bit is mounted such that the action portion is positioned on a side opposite to a side with the rod central axis or the extended line of the rod central axis viewing from the rotational center of the crank. The first eccentric shaft and the second eccentric shaft are disposed such that at a position where the first eccentric shaft causes the rod to reach top dead center (TDC), the second eccentric shaft causes the counter weight to reach bottom dead center (BDC) or a point before the BDC, and at a position where the first eccentric shaft causes the rod to reach the BDC, the second eccentric shaft causes the counter weight to reach a point before the TDC.

Reciprocating tool

In a reciprocating saw, a slider that is reciprocated by a motor protrudes forward beyond a housing accommodating the motor. A blade that cuts a workpiece can be fixed to a joining portion provided at a tip end of the slider. A protector made of an elastic material is attached to the joining portion. The protector is provided with a contact portion capable of contacting the blade fixed to the joining portion.
