モータ6を最大回転数で回転駆動覆ることができる。A speed change switch 16 installed above the trigger 14 at the upper end of the battery compartment 2 closes and closes the operating circuit connected to both terminals of the battery 5 and both terminals of the motor 6 by pressing and releasing cB of the trigger 14. Both terminals of battery 5 and
[In order to short-circuit both terminals of the motor 6 and generate a back electromotive force when stopping the e-taro by circuiting the two normally closed contacts connected to both terminals of the motor 6 and the operating circuit. The shift switch 16 includes a normally closed contact connected to both terminals of the Tanabata 6, and a movable piece 16a that is connected to the operation pieces 14F of the trigger 1 to 14 so as to be interlocked in the front and rear directions. is inserted in a slidable manner, and is further connected to a speed change control circuit incorporating transistors at each contact point of the speed change switch 16. When the trigger 14 is pressed backward, the movable piece 16a moves against the trigger 14. While moving backward in conjunction, one of the two regular contacts connected between both terminals of the electric i!!50 and both terminals of the t-96 turned ON, and [-Taro sent 1 to the speed change control circuit. Tanabata 6
is started, and further, by adjusting the pressing force on the riggers 1 to 14, the movable piece 15a moves back (by adjusting the Q position, the movable piece 16
The contact between the brush (not shown) and the resistance J of the speed change control circuit and the plate (ii) and 7 fluctuates and the resistance value for the motor changes. It can be rotated at an output rotation speed corresponding to the pressing force, and when the trigger 14 is further suppressed to the vicinity of the tilting end and the movable piece 16a is displaced toward the backward end, +'+
The other of the normal contacts f is turned on, 1) 42 speed change control circuit is short-circuited, the resistance value of the motor 6 is reduced, and the motor 6 can be rotated at the maximum rotation speed.

The above-mentioned junctions of the two terminals each become O(koF), and the supply of power from the battery 5 to Shitaro is stopped, and
The normally closed contact is turned on and the voltage between both terminals of the motor 6 is 'f'.
r1 is connected, the motor 6 can be braked by the armature brake, and the rotation of the motor 6 can be stopped.

Then, insert the middle finger U1 with the little finger U3 in contact with the trigger 14 so that it can be pressed, and grip 1.
Turn a and press thumb U4 at a position close to the rotation axis a of the φλ tool.
I! above trigger 14 to hold it together! AI is installed, and the lower end of the rear end surface 15a and the trigger 1 in the released state
The upper end of the front end surface 14b of No. 4 is disposed in a substantially continuous manner with a slight gap therebetween.

じ締め作業や穿孔作業を正確化しうる効果がある。Now, in this example, the housing 1 is used in order to grip the grip 1a of the housing 1 at a position close to the rotational axis a of the rotary tool by using the middle finger U1 adjacent to the ring finger U2 for operating the gripper. Concave portion 15 located above and adjacent to the trigger 14
Because of this, it is possible to stably and strongly grip the tool body to improve workability and maneuverability, and also to precisely move the tool body in the direction parallel to the rotational axis a with respect to the workpiece surface. It has the effect of effectively applying pressing force to the surface to be machined and making screw tightening work and drilling work more accurate.

しうるので操作性を著しく良化することができる。In particular, in the case of a battery built-in power tool in which the battery 5 is housed in the grip 1a as in this example, the grip portion is extended in the vertical direction, making it possible to stably operate the grip while operating the grip 1a. Although it will be difficult, place your finger on the recessed part 15.
++ Since the b-grip 1a can be gripped above the trigger 14, the operability can be significantly improved.
