Title:
Power tool
Document Type and Number:
Japanese Patent JP6016602
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric power tool which enables an entire substrate for a brushless motor etc. to be fixed to a stator of a brushless motor achieving sufficient strength.SOLUTION: An impact driver 1 includes: a brushless motor 10 having a stator 32 and a rotor 30 which may rotate relative to the stator 32; and an output part (a spindle 14, a hammer 16, and an anvil 18) driven by the brushless motor 10. A circuit board 60 is fixed to the stator 32 and a wiring connection part 91 is provided on the circuit board 60. An outer shape of the circuit board 60 is formed so as to be smaller than an outer shape of the stator 32.
