Abstract: A rotary tool includes a motor, a final output shaft, a housing, a detecting mechanism, an interrupting mechanism and a solenoid. The motor includes a motor body and a motor shaft. The final output shaft is configured to be rotationally driven by torque transmitted from the motor shaft. The housing houses the motor and the final output shaft. The detecting mechanism is configured to detect a motion state of the housing. The interrupting mechanism is provided on a transmission path of the torque from the motor shaft to the final output shaft, and configured to interrupt transmission of the torque. The solenoid includes a linearly movable actuation part and is configured to mechanically actuate the interrupting mechanism via the actuation part based on the motion state of the housing detected by the detecting mechanism.

Abstract: A hammer drill includes a housing, a tool holder, a hammering member, a gear, and a conversion member. The gear is switched to a first state where a rotation of the intermediate shaft is transmitted and a second state where the rotation of the intermediate shaft is not transmitted, and a mode switching member is configured to perform a switching operation of the state of the gear from an outside of the housing. The switching of the state of the gear by the mode switching member provides at least two operation modes of a hammer drill mode where the gear integrally rotates with the intermediate shaft to generate the rotation and a reciprocation of the hammering member on the tool holder and a hammer mode where the gear is separated from the rotation of the intermediate shaft to generate only the reciprocation of the hammering member to be selectable.

Abstract: An electric power tool includes a relay, an electric circuit, and an operation member. The relay has a coil, contacts, and an on-switch. The relay is configured such that the coil is energized when contacts are closed by an on-switch being pressed, and contacts are held in a closed state by an electromagnetic force of coil when coil is energized. In the electric circuit, electric power from power source is supplied to motor and coil of relay, and contacts are connected in series between power source and motor. The operation member is configured to move in reciprocating manner between tool stop position at which the motor stops and tool drive position which the motor runs, where the operation member is configured to locate away from on-switch of the relay at the tool drive position and configured to press the on-switch at a position other than tool drive position.

Abstract: A power tool for driving an accessary removably held between first and second clamp parts includes a first shaft having the first clamp part, a second shaft for moving the second clamp part, a holding member movable relative to the second shaft, a moving member for moving the holding member, and a biasing member for biasing the moving member. The second shaft is disposed inside the first shaft. The holding member enables the second clamp part and the first clamp part to hold the tool accessary therebetween in a first position, and disables the second clamp part and the first clamp part from holding the tool accessary in a second position. The moving member moves the holding member from the first position to the second position, and the biasing member biases the moving member when the holding member is located in the second position.

Abstract: A rational technique which can realize vibration suppression and reduction of unstable driving elements of a striker. A representative power tool, a first compensation mechanism moves a swinging mechanism from a swinging mechanism reference position to a swinging mechanism moving position and moves a cylinder to a second side, thereby increasing the volume of an air chamber. Further, the second compensation mechanism moves an intermediate element from an intermediate reference position to an intermediate element moving position and moves a striking element to the second side, thereby compensating the volume of the air chamber.
