发明名称 Electrical power tool
摘要 In view of the above problem, the present invention is to provide an electrical power tool which enables a user to intuitively grasp a rotation direction and a rotation speed of a tip tool. The electrical power tool 1 comprises a chuck 2 provided at a tip of a tool body 3, and rotatable with a tip tool held, and an operation switch 7 having operation protrusions 6 exposed to both side surfaces of a tool body 3 so as to be able to operate, respectively bilaterally symmetrically protruded with a rotation axis of the chuck 2 therebetween, coaxially rotatable with the chuck 2, and urged so as to be self-restored to a neutral position. The chuck 2 is rotated in a direction according to a rotation direction of the switch 7 at a speed according to a rotation angle from the neutral position of the operation switch 7.
