Abstract
An impact driver in which a drill mode can be selected without fail is provided. In a hammer case, a connecting sleeve is provided so as to be slidable back and forth. At the backward position, the connecting sleeve engages with only a first engaging tooth provided on the outer circumference of the hammer for rotating integrally. At the forward position, it engages with both the first engaging tooth of the hammer and a second engaging tooth of an anvil for rotating integrally with both of them, and thus a drill mode is obtained. Further, an operating bolt is provided in the hammer case to be inserted into a concave groove of the connecting sleeve through a guide groove formed in the hammer case. The operating bolt slides the connecting sleeve to the forward or backward position by its movement in the guide groove.
