Abstract: A portable cutter has a base member, a main body, a cutting blade, a protection member, a dust collection member, and a guide member. The base member moves on a workpiece, the base member having a shaft provided in proximity to one end thereof. The main body is coupled to the base member. A posture of the main body with respect to the base member is changeable. The cutting blade is attached to the main body and driven to cut the workpiece. The cutting blade has an outer periphery. The protection member covers a part of the outer periphery of the cutting blade. The dust collection member has an inlet provided in proximity to the outer periphery of the cutting blade for drawing and collecting dust. The guide member is pivotably supported to the shaft of the base member for guiding the dust to the opening of the dust collection member.

Abstract: There is provided an electric power tool having a plurality of operation modes with different rotation speeds at least in a predetermined load range. The electric power tool is capable of switching between the operation modes when a predetermined condition is satisfied even during a motor is driven, and configured such that a rotation speed of the motor is changed smoothly or in a stepwise manner at the switching between the operation modes.

Abstract: A power tool includes a housing, an electric motor accommodated in the housing, a secondary battery that supplies electric power to the electric motor, a handle provided at the housing, a trigger switch provided at the handle for controlling electric power supply to the electric motor, a residual capacity display for displaying a residual capacity of the secondary battery, and a lock-release switch provided at the handle and configured to allow the trigger switch to be operable and to start displaying the residual capacity at the residual capacity display upon manipulation to the lock-release switch.

Abstract: According to an aspect of the present invention, there is provided a power tool including: a wheel guard detachably attached to an attachment portion of the power tool; a fastening portion connected to the wheel guard; and a manipulation lever connected to the fastening portion at one end thereof so that the fastening portion is fastened to or released from the attachment portion by operating the manipulation lever, wherein the manipulation lever is moved to a first position in which the fastening portion is fixed to the attachment portion and to a second position in which the fastening portion is pivotable with respect to the attachment portion, and wherein, when the manipulation lever is positioned at the first position, the other end of the manipulation lever is positioned at an outer circumference of the wheel guard.

Abstract: The portable cutting tool includes a housing that rotatably supports a cutting blade, a base to be connected with the housing and having an opening through which the cutting blade is protrudable, and a protrusion amount changing mechanism. The protrusion amount changing mechanism has a link part extending from the base, and a fixing part which is provided at the housing, comes to a fixed state with respect to the link part when moved in one direction in a direction orthogonal to a rotational shaft of the cutting blade, and comes to a moving state to be movable with respect to the link part when moved in an other direction in the direction orthogonal to the rotational shaft, whereby a protrusion amount of the cutting blade from the second side of the opening is changed as the fixing part is moved with respect to the link part.

Abstract: A power tool has a handle holder portion having a semispherically bulging outer circumference, and an arm portion enclosing the handle holder portion and having a semispherically recessed inner circumference. The bulging outer circumference of the handle holder portion is fitted in the recessed inner circumference of the arm portion. An elastic member is clamped between a power tool body and a handle around the handle holder portion in the radial direction perpendicular to the center axis of the protruding direction of the handle holder portion. A bulging portion for limiting the sliding range of the arm portion is disposed at the leading end of the handle holder portion.
