A pawl is located beside the driving member and has a toothed surface for being engaged with the teeth of the driving member. A selection member is connected to the pawl. A substantially U-shaped first spring member and a substantially U-shaped second spring member are respectively connected to the head and the pawl is enclosed and clamped between the left biasing portions and the right biasing portions of the first and second spring members.
