PURPOSE:To reduce the thickness of a timepiece body by setting a piezoelectric element being a driving body and a pawl lever on a plane, by providing a pulley pin being a projection to a pulley being a rotary member and engaging said pulley pin with the pawl lever being a slide member. CONSTITUTION:A pulley pin 201 being a projection is provided on a pulley 209 being a rotary member so as to be engaged with a pawl lever 211 being a slide member. In this constitution, the torque transmitted to the pulley 209 is transmitted to the pawl lever 211 through the pulley pin 210 provided on the pulley 209 and the pawl lever 211 is guided into plane linear motion with respect to a main plate 201. By this method, a piezoelectric element 1 being a driving body and the pawl lever 211 can be set on a plane and the thickness of a timepiece body can be reduced. |
