Abstract
A front lid opening and closing assist which enables an easy and safe operation of opening and closing a front lid of a keyboard instrument. A buffer in the front lid opening and closing assist has a first damping mechanism for damping the front lid when pivoted from a neutral position to an open position, and a second damping mechanism for damping the front lid when pivoted from the neutral position to a closed position. When the front lid is pivoted beyond the neutral position, it spontaneously pivots toward the open or closed position by its own weight. However, this motion is damped by the first and second damping mechanisms, which results in a slowed pivot motion of the front lid. As a result, a user can safely open or close the front lid relative to a back lid, with only minimal force for supporting the front lid.
