    Abstract: A sliding cutting machine (1) includes: at least one slide bar (51) having an elongated shape; a slide base (17) slidably mounted on the at least one slide bar (51); and a cutting-machine main body (10) mounted on the slide base (17) such that it is movable in an up-down direction relative to the slide base (17). The cutting-machine main body (10) includes: an output shaft (27) that extends in an axial direction orthogonal to an extension direction of the at least one slide bar (51) and on which a cutting tool (11) is mounted; and an electric motor (21) disposed between the cutting tool (11) and the at least one slide bar (51), as viewed along the extension direction of the at least one slide bar (51), while the output shaft (27) is rotating and the cutting tool (11) is vertical.

    Abstract: An operation member has a higher degree of design freedom in, for example, the position and the amount of displacement of an operation part, and the force used for operation. A portable cutting machine includes a base, an electric motor, a blade rotatable by the electric motor, a movable cover covering a lower part of the blade protruding downward from the base and rotatable to be open, an operation lever located frontward from a rotation center of the blade and rotatable, and a transmission lever rotatable to push and open the movable cover when pushed by the operation lever.

    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.

    Abstract: An illuminator that emits light from a radially outer portion of the cutting tool toward the cutting tool includes a first light source and a second light source, and a first lens and a second lens. The first lens has a first emission surface including a first outermost portion located farthest and at a first distance from a first center axis including a first light source center of the first light source and perpendicular to the first light source. The second lens has a second emission surface including a second outermost portion located farthest and at a second distance from a second center axis including a second light source center of the second light source and perpendicular to the second light source. A distance between the first center axis and the second center axis is shorter than a sum of the first distance and the second distance.

    Abstract: Twisting of a locking member due to cogging torque is reduced without lowering the locking and unlocking operability for a user. A power tool includes a housing, an electric motor located inside the housing and including a permanent magnet, a shaft rotatable about an axis relative to the housing to transmit power from the electric motor, a locking member movable between a lock position and an unlock position in a nonenergized state of the electric motor and engageable with the shaft at the lock position to lock rotation of the shaft, and an abutting member that applies, to the locking member at the lock position, a force in a direction opposite to an axial torque caused by the permanent magnet and applied to the locking member.

    Abstract: A cutting device main body with a saw blade in a tabletop cutting device, supported so as to be swingable in an up-to-down direction with respect to a table on which material to be cut is placed, aims to improve operability for attaching and detaching the battery. A sliding direction for attaching and detaching the battery is set to be a tilting direction angled with respect to an up-to-down moving direction of the cutting device main body in a surface direction of a cutting blade. Because of this configuration, all of an operation force for attaching and detaching the battery is not applied to the up-to-down moving direction of the cutting device main body. As a result, the cutting main body is not moved in an easy manner and operability for attaching and detaching the battery is improved.

    Abstract: In a band saw that is provided with a tension adjustment mechanism in which tension for an band saw blade can be adjusted, first and second wheel support shafts are provided in paired first and second wheel support portions, respectively, such that the first support shaft is parallel to the second support shaft. The first wheel support portion is configured to be movable in a direction in which a straight line extends, the straight line being perpendicular to both the first and second wheel support shafts. A first support is provided at a first end of the first wheel support portion, and a second support is provided at a second end of the first wheel support portion. Furthermore, an intermediate support is provided between the first support and the second support. A first load and a second load are configured to be applied to the second support and the intermediate support, respectively, such that the first load and the second load are parallel to the wheel support shaft and the direction of the first load is opposite to that of the second load.
