摘要： It is an object of the invention to provide an effective technique for a motor support structure of a power tool to reduce vibration. A representative reciprocating power tool may include a tool body, a tool bit, a grip, a motor, a tool bit side bearing, a grip side bearing, a tool bit side bearing housing, a grip and an elastic element. The tool bit side bearing housing houses the tool bit side bearing, while the grip side bearing housing houses the grip side bearing. The elastic element is disposed between the grip side bearing housing and the grip wherein the grip side bearing housing is elastically supported by the grip via the elastic element. According to the invention, because the grip is adapted to support the grip side bearing housing via the elastic element and the rigidity of the grip side bearing housing can be increased and vibration of the grip side bearing housing can be reduced. Further, the elastic element can absorb manufacturing errors caused between the tool body and the grip when the grip is mounted to the tool body.

摘要： A handle for a tool includes a handle body, an operation device and a pair of clamp halves. The operation device has an operation member operable by an operator. At least one of the clamp halves can move relative to the handle body along an axis. As the operation member is operated, the one of the handle halves moves along the axis, so that the distance between the handle halves can be changed for clamping or releasing a portion of the tool.

摘要： Mode switching is reliably performed with a durable and small-sized configuration. A clutch pin (40) is provided in a reduction shaft (34) and configured to be slidable by an operation from outside, and a driven gear (38) is inserted onto the reduction shaft (34) and configured to be rotatable separately from the reduction shaft (34), so that a clutch mechanism is provided. By switching the clutch mechanism, a selection can be made between a hammer drill mode and a hammer mode. Meanwhile, the clutch pin (40) is configured to be slidable to a sliding position where the clutch pin (40) runs through the reduction shaft (34) so as to be capable of protruding upward beyond the reduction shaft (34), and at the sliding position, the clutch pin (40) engages with an engagement hole (46) provided on the tool holder (7) side so that a rotation of the tool holder (7) can be locked, whereby in the hammer mode, a selection can be further made between a neutral state where the clutch pin (40) does not engage with the engagement hole (46) and a rotation locked state where the clutch pin (40) engages with the engagement hole (46).

摘要： A technique for improving the vibration-proof effect and usability of a handle is provided in an impact tool. An impact tool is provided which linearly drives a tool bit in an axial direction thereof to cause the tool bit to perform a predetermined hammering operation. The impact tool includes a motor, a striking mechanism part, that is driven by the motor and causes the tool bit to linearly move, a tool body that houses the motor and the striking mechanism part, an outer shell housing that covers at least part of the tool body and is connected to the tool body via a vibration-proofing first elastic element so as to be movable in a direction transverse to the axial direction of the tool bit with respect to the tool body, and a handle which is designed to be held by a user and connected to an opposite side of the outer shell housing from the tool bit via a vibration-proofing second elastic element so as to be movable in the axial direction of the tool bit with respect to the outer shell housing.
