    • PROBLEM TO BE SOLVED: To provide a technique reduced in cost and enhanced in assemblability by facilitating the laying of cables related to an electric switch for electrifying and driving a motor in a hammering tool for performing predetermined processing operations by securing switch operating members at the operating positions. SOLUTION: This hammering tool comprises: the motor 111; the electric switch 151 for electrifying and driving the motor; the first switch operating member 153; the second switch operating member 155; and a mode selector member 165 for selecting the drive mode of a tool bit. When the first drive mode of the mode selector member 165 is selected, the first switch operating member 153 is fixed, and the on/off operation of the electric switch 151 by the second switch operating member 155 is allowed. When the second drive motor of the mode selector member 165 is selected, the second switch operating member 155 is fixed, and the on/off operation of the electric switch 151 by the first switch operating member 153 is allowed.
