Abstract: A driving tool with a mechanical spring uses urging force from a striking spring as driving force and switches its operation mode. The tool includes a striking driver to strike a fastener, a striking spring urging the driver in a driving direction, a contact arm movable to a retracted position in a counter-driving direction in response to pressing against a workpiece, a trigger movable to an on-position in response to user operation, and a mode selector switch to switch the operation mode between continuous drive mode and single drive mode. A driving operation is performed in the continuous drive mode in response to the contact arm moving to the retracted position and the trigger moving to the on-position in any order, and in the single drive mode in response to the contact arm moving to the retracted position and the trigger moving to the on-position in the stated order.

Abstract: A reciprocating tool includes a housing, a support body, a slider, a motor, a driving mechanism, a first biasing member, a manipulation member and a first change mechanism. The housing has a first axis that defines a front-rear direction of the reciprocating tool. The support body is supported within the housing. The slider is supported by the support body to be linearly movable. The driving mechanism is operably coupled to the slider and configured to reciprocally move the slider relative to the support body using power of the motor. The first change mechanism is operably coupled to the manipulation member and configured to selectively enable and disable the first biasing member to bias the slider in response to manipulation of the manipulation member. When biasing of the slider by the first biasing member is enabled by the first change mechanism, the first biasing member biases the slider downward.

Abstract: An electric work machine in one aspect of the present disclosure includes an electric power input terminal, a motor, a circuit board, a first heat dissipation plate, and a second heat dissipation plate. The circuit board includes a first surface and an electronic circuit on the first surface. The electronic circuit controls supply of AC power to the motor. The electronic circuit includes an electronic component that generates Joule heat. The first heat dissipation plate is spaced from the first surface by a first distance in parallel to the first surface. The second heat dissipation plate is spaced from the first surface by a second distance in parallel to the first surface. The second heat dissipation plate is thermally coupled with the first heat dissipation plate. The second distance is smaller than the first distance.

Abstract: A power tool having a rotary hammer mechanism has a first motor; a driving mechanism configured to operate by power of the first motor in an action mode selected from a plurality of action modes including a first mode of at least rotationally driving a tool accessory and a second mode of only linearly driving the accessory; a tool holder configured to be rotationally driven by torque transmitted from the first motor; a second motor; a clutch member configured to transmit torque to the holder in a transmitting position and to interrupt the transmission in an interrupting position; and a transmitting mechanism configured to convert rotation of the second motor into linear motion and transmit the linear motion to the clutch member. When the tool body excessively rotates around the driving axis, the second motor moves the clutch member from the transmitting position via transmitting mechanism to interrupt the transmission.

Abstract: A power tool having a rotary hammer mechanism has a motor, a driving mechanism, a tool body that houses the motor and the driving mechanism, a handle having a grip part, and a first operation member. The driving mechanism is configured to operate by power of the motor in an action mode that is selected from a plurality of operation modes including a first mode of at least rotationally driving a tool accessory around a driving axis and a second mode of only linearly driving the tool accessory along the driving axis. The grip part extends in a direction crossing the driving axis and is configured to be held by a user. The first operation member is on the tool body and faces the grip part. The first operation member is configured to be manually operated by the user to change the action mode of the driving mechanism.
