<p>An electric power tool is provided comprising a percussion mechanism (7) for applying percussion to an output shaft (8) in the axial direction at a backward position of the output shaft (8), and a chuck sleeve (109) provided at the top of the output shaft so as to be movable back and forth in the axial direction as well as biased to one sliding position by a biasing means. There is provided only one biasing means (110) for biasing the output shaft (8) to a forward position as well as the chuck sleeve (109) to a backward position, which reduces the number of parts.</p> |
