ABSTRACT:
A power tool transmission device includes a base, a switch portion, a vibration member, a press portion, a transmission shaft and a casing. When the projections press the position plates, bosses on the position plates engage ribs formed outside the outer ring so as to limit the rotation of the outer ring and when the first gear and the second gear are intermittently disengaged with each other, a vibration effect is provided to the transmission shaft.
