An electric tool () is provided with an output part () and a grip part (). An elastic member () is provided between an outer wall surface () of a trigger switch () and a housing inner wall surface () of the grip part ().

Electric tool

A rotary tool () having a plurality of switchable modes is provide with a trigger () and a switching lever () disposed around a grip () for selecting a rotational direction of a motor (). The switching lever () is operated between a forward rotation state, a reverse rotation state, and a neutral state. A switching of the modes is executed when the switching lever () is positioned in the neutral state and the trigger () is pulled.

Rotary tool

A rotary tool is provided with a mode selecting part that selects one operating mode from a predetermined plurality of operating modes when a mode switching button is pressed. The plurality of operating modes include: a first auto stop mode where a motor rotates only for a first time period after an impacting operation is detected; and a second auto stop mode where the motor rotates only for a second time period which is shorter than the first time period after the impacting operation is detected.

A power tool includes a housing, a motor accommodated in the housing, a cooling fan arranged coaxially with the motor, a trigger switch configured to activate the motor, a motor control board on which a switching device is mounted to drive the motor, and a coupling unit provided below a bottom surface of the motor. The motor control board is fixed to the motor via the coupling unit such that the motor control board is disposed below the motor and above the trigger switch.

Power tool

A hammering tool includes, within its tool main body, a piston which reciprocates by using a motor as its drive force, a hammering member which carries out its hammering operation in linking with the reciprocating motion of the piston, and an intermediate member which transmits a hammering force of the hammering member to a top end tool mounted on the top end of the tool main body. The tool main body further includes a measuring device which measures a hammering state of the hammering member and a control device which controls the number of rotations of the motor. The control device, according to measurement results of the measuring device, determines the limit number of times of hammering where the hammering member becomes unable to follow the reciprocating motion of the piston, and thus controls the number of rotations of the motor.

Hammering tool

In a driving tool, a diameter of an intermediate member is enlarged to increase a mass of the intermediate member and an outside diameter of a cylinder at a position where the intermediate member is internally provided is enlarged in accordance with the enlarged diameter of the intermediate member. Further, in the driving tool, a bearing thickness of a ball bearing is reduced correspondingly to a dimension of the enlarged outside diameter of the cylinder and a washer is provided at a part where the ball bearing abuts on the cylinder in the forward and backward moving direction thereof.
