Abstract: An electric work machine (1; 201) includes: a motor housing (6; 212) having a tube part (6C; 212C) and a bottom part (6M; 212M); a brushless motor (5; 228) having a stator (20), which has a first contact surface (58F; 258F), and a rotor (21; 231) disposed in the stator; a baffle plate (25; 285); and an output shaft (31; 292). The stator includes a tube-shaped stator core (50) having a ring-shaped second contact surface (50S; 250S) that is opposite of the first contact surface, and coils (56; 256) 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 (25S; 285S) 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 (68; 288).

Abstract: A portable cutting machine allows a large battery pack to be attached on the rear of a handle unit without largely increasing the height of the handle unit. A portable cutting machine to which a battery pack having a connecting surface is attachable includes a base that comes in contact with a workpiece, a cutting machine body supported on an upper surface of the base and including a cutting blade protruding from a lower surface of the base to cut the workpiece, an electric motor that drives the cutting blade, and a handle unit grippable by a user, and a battery attachment portion located opposite to the cutting blade with respect to the handle unit to receive the battery pack attachable by sliding in a posture with the connecting surface facing sideward.

Abstract: 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.
