An electric work machine () includes: a motor housing () having a tube part (C;C) and a bottom part (M;M); a brushless motor () having a stator (), which has a first contact surface (F;F), and a rotor () disposed in the stator; a baffle plate (); and an output shaft (). The stator includes a tube-shaped stator core () having a ring-shaped second contact surface (S;S) that is opposite of the first contact surface, and coils () wound on the stator core. The stator is held by the motor housing with the first contact surface in contact with the bottom part. A protruding part (S;S) of the baffle plate contacts the entire circumference of the second contact surface of the stator core and is fixed to the motor housing by three or more screws ().

Electric work machine and manufacturing method therefor

Portable electric circular saw

Two 18V-type rechargeable batteries (and) are attached in series so as to allow a 36V-type tabletop cutting device (C) to be utilized. By utilizing the 18V batteries which are highly prevalent for electric tools, it is possible to use the 36V-type tabletop cutting device (C) as well as to reduce costs for the batteries.

A cutting device may include a friction reducing device arranged in an operational force transmission path between an operation member and a fixing device that can fix a circular cutter to a rotational shaft of a cutting unit.

Cutting devices

An interposing member is interposed between a base part of the fence plate and a top plate part of a base, and a position of the fence plate is changed on the interposing member. Because of this, deflection etc. of the top plate can be reduced and variation of an operating angle of an operating lever can be reduced when fixing the fence plate to the base.

Cutting device

A cutting tool includes a tool unit having a rotary circular blade, a movable cover mounted to the tool unit and having a cover body movable in a moving direction to cover and uncover a part of the rotary circular blade by the cover body, and a position adjusting mechanism configured to adjust the position of the cover body of the movable cover in an adjusting direction different from the moving direction.
