PURPOSE:To enhance display effect, by repeatedly performing the rising and falling motion of a clock body by the position of a wt. CONSTITUTION:When the wt. 9 of a sec hand wheel 8 is present at 12 o'clock position being a top dead point or at 6 o'clock position being a bottom dead point, a clock body 5 is well-balanced with a balance mass 6 as shown by a solid line and a swinging rod 3 is held under a horizontal state but, when the wt. 9 is present at 3 o'clock position, the gravity point of the clock body 5 moves to a right direction and the balance with the balance mass 6 is lost and the clock body 5 rises as shown by a broken line. contrarily, when the wt. 9 is present at 9 o'clock position, the gravity point moves to a left direction and the balance with the balance mass 6 is lost to fall the clock body 5. As mentioned above, because the clock body 5 repeatedly performs rising and falling motion, visually pleasant effect can be imparted. |
