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: 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 rebar tying tool may include a controller configured to selectively execute one of a plurality of control modes including a single-action control mode and a repetitive-action control mode. While the controller executes the single-action control mode, a tying mechanism may perform a tying operation in response to an activation of a manipulation member by a user. While the controller executes the repetitive-action control mode, the tying mechanism may perform the tying operation in response to a detection of the at least one of rebars by a detection mechanism.

Abstract: An electrical hammer (100) comprises a main housing (101), a hand grip (500) connected to the main housing (101) via a compression coil spring (321). In the electrical hammer (100), a hammer bit (119) is driven by a first motion converting mechanism (120) and thereby a hammering operation is performed. During the hammering operation, the hand grip (500) is moved against the main housing (101) in a state that biasing force of the compression coil spring (321) is applied on the hand grip (500). Further, the electrical hammer (100) comprises a second motion converting mechanism (220) which drives a counterweight (231).

Abstract: A hammer drill (101) comprises a main body (103) which houses a driving motor (110) and a driving mechanism and a handle (109) which is movable to the main body (103). Further, a coil spring (160) which biases the handle (109) is provided. In a state that the coil spring (160) biases the handle (109), the handle (109) is moved against the main body (103) in a longitudinal direction of a hammer bit (119) and vibration transmission from the main body (103) to the handle (109) is prevented.

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.

Abstract: A work tool includes a motor, a driving mechanism, a body housing and a handle. The driving mechanism is configured to perform an operation of linearly reciprocating the tool accessory along a driving axis extending in a front-rear direction. The handle includes a grip part extending substantially in an up-down direction, and a battery-mounting part provided on a lower side of the grip part. An upper end portion of the handle is connected to a rear end portion of the body housing via an elastic member so as to be movable relative to the body housing. A lower end portion of the handle is connected to the rear end portion of the body housing so as to be rotatable relative to the body housing, around a rotation axis extending in a left-right direction. The rotation axis is located on a lower side of the battery-mounting part.
