An electric working machine may include: an electrical component; a first space in which the electrical component is disposed; a partition wall separating the first space from a second space different from the first space, the partition wall including a first communication opening communicating the first space and the second space; and a first one-way valve disposed at the first communication opening.

Electric working machine

A working machine may include a working part, a fan, a motor configured to drive the working part and the fan, a body housing accommodating the fan and the motor and including a battery accommodating part which defines a battery accommodating space and a battery pack accommodated in the battery accommodating part. The battery accommodating part may include an air intake opening for intaking air from inside of the body housing into the battery accommodating space and an air exhaust opening for exhausting air from the battery accommodating space to the inside of the body housing. An air intake tube protruding from the battery accommodating part to the inside of the body housing may be connected to the air intake opening of the battery accommodating part.

Working machine

A battery mount device may include a housing to which a battery pack is detachably attached, and a cover attached to the housing so as to cover the battery pack and configured to open and close by rotating around a rotation axis. Force in a direction closing the cover may act on the cover in a state where the battery mount device is placed on a horizontal plane. The battery-mounted device may further comprise a cover holding mechanism capable of holding the cover in an open state. The cover holding mechanism may include a cover holder configured to move, in response to an operation by a user, between a holding position where the cover holder interferes with a rotating motion of the cover and a released position where the cover holder does not interfere with the rotating motion of the cover.

Battery mount device

A hand-held power tool includes a motor having a stator and a rotor, the motor being configured to rotate the rotor at a speed of at least 40,000 rpm, an output shaft directly driven by the rotor, a tool accessory shaft configured to support a tool accessory, and a two-stage speed reducing transmission operably connecting the output shaft to the tool accessory shaft. The two-stage speed reducing transmission is configured to drive the tool accessory shaft at a rate less than the rotor speed, for example, at a rate less than or equal to 37.5% of the rotor speed.

Power tool with high-speed electric motor

A handheld work machine comprises a main body comprising a prime mover and a handle fixed to the main body and configured to be gripped by a user. The handle is formed by pipe material and at least one reinforcement member is disposed at a longitudinal portion of the handle that configures a part of the handle. The reinforcement member may be formed by pipe material and preferably disposed inside the handle. The longitudinal portion where the reinforcement member is disposed may preferably include a fixed portion of the handle that is fixed to the main body.

Handheld work machine

A handheld engine-driven cutter is provided with a disk blade and a main body that drives the disk blade. The main body comprises a four-stroke engine, an oil supplying opening from which engine oil is supplied, and an oil exhausting opening from which the engine oil is exhausted. In this engine cutter, the oil supplying opening and the oil exhausting opening are both disposed on one side of the main body where one end of a driving axis of the four-stroke engine is located.

Engine-driven cutter

A handheld engine-driven cutter is provided with a disk blade and a four-stroke engine that drives the disk blade. By employing the four-stroke engine, exhaustion of unburned gas and fuel consumption can be reduced. The engine cutter is further provided with a filter through which air provided to the four-stroke engine passes, a carburetor that mixes fuel and the air that passed through the filter, and a casing that houses the filter and the carburetor. The filter and the carburetor are arranged to align on a straight line along a direction of flow of the air passing through the filter and the carburetor.

Engine driven cutter

A handheld engine-driven cutter is provided with a disk blade and a four-stroke engine that drives the disk blade, a filter through which air provided to the four-stroke engine passes, a carburetor that mixes fuel and the air that passed through the filter, a casing that houses the filter and the carburetor, and a filter bracket intervened between the filter and the carburetor, which guides the air having passed the filter to the carburetor. An oil separator is formed integrally with the filter bracket that protrudes out toward the carburetor.

A handheld engine-driven cutter is provided with a disk blade and an engine that drives the disk blade, a filter through which air provided to the four-stroke engine passes, a carburetor that mixes fuel and the air that passed through the filter, a casing that houses the filter and the carburetor, at least one operation member that is operated by a user and connected to the carburetor via a link, and a shaft that is connected to the casing and supports the operation member in a swingable manner. A shaft receiving groove that supports the shaft is formed in the casing.
