PURPOSE: A weight variable damper is provided to prevent the traction loss if the periodic damping of a rotary shaft is unnecessary. CONSTITUTION: A weight variable damper comprises a main weight body(200) and variable weight body(300). The main weight body rotates along with a rotary shaft(100). The main weight body moves the rotary shaft in longitudinal direction and surrounds the outer circumference of the rotary shaft. The variable weight body comprises a body(312) and a lateral plate(324). The body surrounds the outer circumference of the main weight body. The lateral plate is expanded to the rotary shaft. The variable weight body revolves along with the rotary shaft when the rotary shaft is moves to the lateral plate. |
