Abstract: A power tool includes a motor having a rotatable motor shaft, a first intermediate shaft, and a second intermediate shaft extending in parallel to the first intermediate shaft. An output shaft removably holds a tool accessory and has a driving axis. A motion-converting mechanism converts rotation of the first intermediate shaft only into linear reciprocating motion and thereby hammers the tool accessory along the driving axis. A rotation-transmitting mechanism transmits rotation of the second intermediate shaft to the output shaft and thereby only rotationally drives the output shaft around the driving axis.

Abstract: A power tool includes a motor having a motor shaft, a first intermediate shaft, and a second intermediate shaft extending in parallel to the first intermediate shaft. An output shaft removably holds a tool accessory and has a driving axis extending in parallel to the first and second intermediate shafts. A motion-converting mechanism converts rotation of the first intermediate shaft to linearly hammer the tool accessory. A rotation-transmitting mechanism transmits rotation of the second intermediate shaft to rotate the output shaft. A rotational axis of the motor shaft intersects, or is skewed relative to, the driving axis. A pair of first gears, e.g., bevel gears, operably couples the motor shaft to a first one of the first and second intermediate shafts. A pair of second gears operably couples the first one of the first and second intermediate shafts to a second one of the first and second intermediate shafts.

Abstract: An impact tool includes a motor, a driving mechanism, a body housing, a battery-mounting part, a first detection part and a control part. The driving mechanism is configured to linearly drive a tool accessory along a driving axis by power of the motor, the driving axis extending in a front-rear direction of the impact tool. The body housing houses the motor and the driving mechanism. The battery-mounting part is configured to removably receive a battery. The first detection part is configured to detect a rearward push of the tool accessory relative to the body housing. The control part is configured to start driving of the motor in response to detection of the rearward push of the tool accessory by the first detection part.

Abstract: A dust collector for an electric power tool includes a main body case, a tubular sliding portion, and a dust collection portion. The main body case is mountable to an electric power tool. The tubular sliding portion is disposed on the main body case. The sliding portion includes a nozzle on a front end thereof. The nozzle includes a suction opening. The dust collection portion is configured to accumulate dust suctioned from the nozzle. The sliding portion includes a guided portion supported by a guiding portion disposed on the main body case. The guided portion is supported slidably in a front-rear direction, and the guiding portion and the guided portion are disposed in a region on a half side with respect to a line on a cross section passing through a center of the sliding portion.

Abstract: Reciprocating power tool is provided which is improved in vibration isolation of the handle. The reciprocating power tool has a tool body and a handle connected to the tool body. When an axial direction of a tool bit is defined as a longitudinal direction, the handle extends in a vertical direction crossing the longitudinal direction. Further, an upper region of the handle is connected to the tool body via an elastic member and a lower region of the handle is connected to the tool body via a support shaft that it can rotate around an axis of the support shaft in a transverse direction crossing both the longitudinal direction and the vertical direction with respect to the tool body. When the handle rotates around the support shaft with respect to the tool body, the elastic member reduces vibration which is caused in the tool body and transmitted to the handle.
