A one side actuating springwhich can contact the unlocking stoneis provided in the blade. When a working reference line, which is a line connecting the rotation center of the balanceand the rotation center of the blade, is set to a reference, the one side actuating springis disposed at an angle so that a distance of the tip of the one side actuating spring from the working reference line is increased as the tip is separated from the rotation center of the balancein a side opposite to the side at which the escape wheelis present.
