摘要： 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.

摘要： 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.

摘要： 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.
