A positioner positions a guide ruler relative to a workpiece that is adjacent to the guide ruler while more stably retaining the guide ruler at the locked position without causing interference with a cutting operation. A positioner that positions a ruler body relative to a workpiece includes a contact member to be in contact with an edge of the workpiece and extendable along the edge of the workpiece, a support supporting the contact member in a manner rotatable on a lower surface of the ruler body, and a position retainer that retains the contact member at a rotational position.

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.

Portable cutting machine

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.

Power tool

When the protruding length of a cutting bladeprotruding below a lower surface of a baseof a portable machining deviceis set to its maximum length, at least a part of a controllerfor controlling an electric motoris configured to be located behind a handlein the front-to-rear direction. Furthermore, the controlleris disposed so as to be tilted in the left-to-right direction or in the up-to-down direction with respect to the cutting blade. Because of this configuration, the height of the handlecan be restricted and at the same time the controllercan be disposed in a compact manner.

Portable machining device

A communication adapterfor conducting radio communication between a portable machining deviceand a dust collector, such that the dust collectormay operate synchronously with the portable machining devicewith respect to a start/stop operation when performing a cutting task is detachably incorporated in a handleof the portable machining device. Because of this arrangement, a high level of dust-proof ability as well as ease of maneuverability in attaching and detaching the communication adaptercan be achieved.
