A seesaw button apparatus is provided to prevent decrease of an elastic force after long use by using a tension rib serving as a seesaw button implemented on front panels of electronic apparatuses. A seesaw button includes upper and lower push buttons(110,120) as well as upper and lower push protrusions(140,150). The upper and lower push buttons are formed on an upper portion of the seesaw button. The upper and lower push protrusions(140,150) are formed on a lower portion of the seesaw button to operate a switch. A support bar(210) supports a seesaw operational point of the seesaw button. A planar elastic rib is formed on a predetermined position of the support bar(210) to provide elastic forces to upper and lower push buttons of the seesaw button according to the pressure applied on the upper and lower push buttons(110,120). Upper and lower elastic rib push protrusions(180,190) are formed at predetermined positions on the upper and lower push buttons(110,120), respectively.
