摘要： An effective technique for detecting several load conditions different in presence or absence and magnitude of load applied to a tool bit is provided in a hand-held tool. A hand-held tool 101 performs a predetermined operation while pressing a tool bit 119 mounted in a front end region of a tool body 103 against a workpiece. A plurality of detecting sensors 161 of different kinds detect several load conditions different in presence or absence and magnitude of load applied to the tool bit 119. The hand-held tool 101 includes at least one of an indicating device 171 which indicates the load conditions based on a result detected by the detecting sensors 161, and a driving control device 135 which controls driving of the tool bit 119 based on the detected result.

摘要： It is an object of the invention to provide a technique that contributes to realizing both the switch selecting function and the handle vibration-proofing function, in an impact tool which can switch an operation mode of a tool bit. An impact tool includes a motor 111, a tool body 103, a handle 109, a vibration-proofing cushioning material 161 which connects the tool body 103 and the handle 109 such that the tool body and the handle can move with respect to each other. The impact tool further includes a motor-driving manual operating member 143 disposed on the handle 109, an operation mode switching member 151 disposed on the tool body 101, and a movable member 153. When the operation mode switching member 151 is switched to first operation mode in which the tool bit 119 is continuously driven, the movable member 153 moves the manual operating member 143 from an off position to an on position and locks it in the on position. When the operation mode switching member 151 is switched to second operation mode in which the tool bit 119 is arbitrarily driven, the movable member 153 releases the lock of the manual operating member 143. A vibration-proofing elastic member 143c is disposed in an arbitrary region in the vibration transmitting path. The elastic member 143c prevents vibration caused in the tool body 103 from being transmitted to the handle 109 via a vibration transmitting path in the state in which the manual operating member 143 is locked in the on position by the movable member.
